This study examines how collaborative open source software utilization can impact the competitiveness of product companies. The objective is to examine the impact of substantial collaboration and to provide a framework which describes in detail the rationale for collaboration and leveraging open source software. Open source software has been increasingly adopted as part of the software industry, but it is still unclear how collaborative development can contribute to and be combined with the competitiveness of companies, because of the informal relationship with the community and openness of software. The impact on competitiveness is studied through reviewing literature on theories of competitive advantages, identifying the distinct competitive characteristics of software products, examining the characteristics of open source software, and investigating the prior collaboration strategies of companies. Then two case studies are conducted based on the conceptual understanding. Open source software is defined as an industry wide disruption due to community growth, increased commercial investment, and part of the software asset reaching commercial quality. This has lead to the software industry moving to a transition phase with heterogeneous collaboration strategies across competition. The presented framework details the rationale for collaboration and the different firm-level strategies—integration with existing communities and self-created communities—that can be used to implement collaborative development. Based on the empirical study, collaboration enables companies to concentrate on value creation and more efficient expansion of existing competencies to new markets. The strategic split of software makes possible the reconfiguration of the development value chain and a better match between internal competencies and the external environment. This leads to substantial cost reductions in product development, with the efficiency defined by the firm-level collaboration activities and the characteristics of the chosen communities. The studies also indicate that collaboration does not neglect the companies’ ability to create differentiating value in addition to OSS with, e.g. IPR or network externalities. The research also makes observations and discusses the impact of collaboration on industry competencies, and the possibility of direct competitors converging to similar collaboration strategies.

Tämä tutkimus tarkastelee kuinka yhteistoiminnallinen avoimen lähdekoodin käyttö voi vaikuttaa tuoteyrityksien kilpailukykyyn. Tavoitteena on tutkia huomattavan yhteistoiminnallisen tuotekehityksen vaikutusta ja tarjota viitekehys, joka yksityiskohtaisesti selittää syyt yhteistoiminnalle ja avoimen lähdekoodin käytölle. Avoin lähdekoodi on viime vuosina kasvavissa määrin omaksuttu osaksi ohjelmistoteollisuuden kilpailua, mutta on edelleen epäselvää miten yhteistoiminta voi edistää tuoteyritysten kilpailukykyä, koska suhde yhteisöön on epävirallinen ja lähdekoodi avointa kilpailijoille. Vaikutusta kilpailukykyyn tutkitaan tarkastelemalla kirjallisuutta kilpailuteorioista, identifioimalla erityisiä tekijöitä ohjelmistotuotekilpailussa, tarkastelemalla tekijöitä avoimeen lähdekoodin liittyen, sekä tutkimalla aikaisempia yritysten yhteistoimintastrategioita. Käsitteellisen ymmärryksen pohjalta toteutetaan kaksi tapaustutkimusta. Avoin lähdekoodi määritetään toimialan laajuisena häiriönä yhteisön kasvun, kasvavan kaupallisen investoinnin ja ohjelmistojen saavuttaman maturiteetin takia. Tämän johdosta ohjelmistotoimiala on siirtynyt muutosvaiheeseen, jossa on heterogeenisiä yhteistoimintastrategioita kilpailijoiden välillä. Esitetty viitekehys selostaa yksityiskohtaisesti syyt yhteistoiminnalle ja erilaiset yritystason yhteistoimintastrategiat—integraatio olemassa olevien yhteisöjen kanssa ja itseluodut yhteisöt—, joita voidaan käyttää tuotekehityksen toteutuksessa. Empiirisen tutkimuksen perusteella yhteistoiminnallinen tuotekehitys mahdollistaa investointien keskittymisen arvon luontiin ja tehokkaan olemassa olevien kykyjen käytön laajentamisen. Strategisen ohjelmistojenjaon avulla kehitysarvoketju voidaan uudelleen sovitella ja luoda parempi yhteensopivuus sisäisten kykyjen ja ulkoisen ympäristön välillä. Tämä johtaa huomattaviin supistuksiin tuotekehityksen kuluissa, jolloin supistusten tehokkuuden määrittää sekä yritystason yhteistoiminta, että valittujen yhteisöjen piirteet. Tutkimukset myös osoittavat, että yhteistoiminnallinen tuotekehitys ei tuhoa yritysten kykyä luoda differentioivaa arvoa, esim. aineettoman omaisuuden suojalla tai verkostovaikutuksilla. Tutkimus tekee myös havaintoja ja käsittelee yhteistoiminnan vaikutusta toimialan kykyihin ja mahdollista suorien kilpailijoiden siirtymistä samankaltaisiin yhteistoiminnallisuusstrategioihin. Avainsanat: avoin lähdekoodi, kilpailuetu, kilpailukyky, ohjelmistotuotteet

1. INTRODUCTION
1.1 Background
Until recently product companies such as Nokia, Samsung, and Microsoft have focused solely
on closed-source software products. This has based competitiveness on e.g. lock-in strategies
(Shapiro & Varian, 1999) and the ability to protect intellectual property (Hall, 2003). However,
an alternative to the dominant development paradigm has been introduced by the emergence of
the open source movement (O’Reilly, 1999). The open source software (OSS) definition states
that the source code of software is distributed with the executable binary, the software is free to
use, and anyone is free to modify and redistribute it (Hansen et al., 2002). This phenomenon has
intrigued academic researchers and companies as it goes against the logic of value in closed-
source software production but seems to be a sustainable development model (Lerner & Tirole,
2000; Johnson, 2002).
The success and outcomes of some OSS projects, like the Linux kernel and the Apache net
server (Mockus et al., 2002; O’Reilly, 2004; Fink, 2003), have disclosed the ability of the open
source community to produce commercial quality software. These free programs have been able
to build substantial market shares, e.g. the Apache net server holds over 60% of the web server
market (Casadesus-Masanell & Ghemawatt, 2003; Johnson, 2002). Academic research has
contributed to the understanding of this phenomenon with studies into the motivations of
developers (Lerner & Tirole, 2000; Lakhani et al., 2002), the innovation process (Krogh et al.,
2003), the strengths and problems of the development model, and the technology areas of the
created software (Ioannis et al., 2002; Scacchi, 2002).
This change in software creation has introduced an opportunity for commercial as well as non-
commercial parties to conduct collaborative development. For example, NASA is utilizing OSS
to cut costs and ensure higher quality (Norris, 2004), IBM and Sun are exploiting OSS to drive
down maintenance costs and speed up the development of their products (West, 2003), and
companies like Red Hat are creating their products almost solely from OSS (Young, 1999).
Despite the existing commercial interest, product companies choosing to leverage OSS are
faced with the issues of understanding the explicit rationale and implementation of this strategy
and the impact on their competitiveness. These issues are caused by e.g. openness of source
code (Henkel, 2003) and the collaboration of commercial and non-commercial parties (Long,
2003).

1.2 Research Problem
This research tries to understand the impact on competitiveness of substantial collaborative
research and development (R&D), from the viewpoint of product businesses leveraging OSS.
Collaborative R&D is adapted from Dahlander and Magnusson (2005), and defined as the
company extending their R&D to include the OSS community, with a continuous two-way flow
of software, investment, and effort throughout the life cycle of the product. This collaborative
R&D comprises a substantial amount, e.g. 50% or more, of the product source code.
OSS has gathered a considerable amount of academic interest in the recent years, but there
exists a gap in the understanding of the rationale for collaborative R&D and the impact on
competitiveness. Most of the research has concentrated on explaining the motivations of the
individual developers, the development model, or the culture of the community. Some authors
have studied the benefits for commercial companies, but this has not lead to a thorough
understanding of the competitive implications.
The study builds on the previous research on competitiveness, software products, and OSS. The
approach is to identify the distinct competitive factors impacting software products; analyze the
characteristics of OSS; and to synthesize a framework detailing the rationale and
implementation of collaborative R&D, which is then used as the bases of the empirical study.
The research problem can be summarized as the following question: How can substantial
collaborative R&D impact product company competitiveness?
1.3 Research Objectives
The main objective of the study is:
• To examine the impact collaborative R&D has on competitiveness and to form a
framework that details the rationale and implementation of this strategic approach.
To elaborate on the main objective, the following sub-objectives were considered appropriate:
• To identify and examine the characteristics of OSS; firm-level strategies in which
commercial parties have collaborated with the OSS community; the disadvantages,
challenges, and benefits resulting from these strategies; and the industry wide impact of
OSS.

• Seek empirical validation, feedback, and criticism of the introduced framework with the
help of case studies.
1.4 Scope of the Study
The three subjects of concern— software products, OSS, and competitiveness—are all broad
topics with extensive research related to them. Therefore, it is not in the scope of the study to
build a comprehensive and detailed framework of software business or competitive advantage.
Software has expanded its impact to a critical value adding part in high-technology industries
(MacCormack, 2001), but also in typical manufacturing industries. Therefore we adapt the
definition of Hyvönen (2003), and define that the studies target product businesses include both
individual software products and software produced to be utilized directly with hardware.
The following rules are derived to define the scope of the study:
• The research does not limit itself to licensed software products, but also includes
software meant for consumption with complements, such as hardware.
• Theory of software product businesses is used to examine the competitive factors of
both industry and firm-level phenomenon. However, the questions of specific
characteristics of distinct software markets, when to use OSS, and the evaluation of
different production models are left outside of the scope of the study.
• Collaborative R&D is examined as a tool to create advantages regarding product and
software development. How this advantage is made apart of the whole competitive
dynamism of companies, how it impacts market share, and how it is utilized in the
overall competitive strategy are outside of the scope of the study.
1.5 Research Approach and Methods
The research approach of this study is a combination of a theoretical and empirical approach.
The theoretical approach concentrates on describing software production, OSS, and competitive
theory. The empirical approach tries to assess the findings of the theoretical part, validate the
proposed conceptual framework, and empirically examine the explicit impact of collaborative
R&D.
![Page 10: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/10.jpg)

For the theoretical part, the conceptual approach was chosen as it meets best the objective of
creating a conceptual framework answering the research objectives and working as the bases of
the empirical study. The theoretical part is based on a review of secondary data acquired from
literature, articles, and the Internet.
The empirical parts research method is comprised of two descriptive case studies (Yin, 2003;
Kasanen et al., 1993). For these studies the methods of data collection are documentation,
archival records, active participation, and interviews (Yin, 2003). Quantitative data is used in
combination with empirical observations.
1.6 Research Structure
Chapter 2 reviews existing literature and theories related to competitiveness, competitive
advantage, software business, software production, and OSS. In chapter 3, the findings from the
literature review are synthesized in the form of a framework introducing how collaborative
R&D can impact competitiveness. Chapter 4 reports the two descriptive case studies, the main
findings, and assesses the validity of the proposed framework. The following chapter 5

2. LITERATURE REVIEW
The purposes of the following chapters are to review the theories of competition and
competitive advantages and the literature on software products, their distinct competitive
characteristics, and OSS development.
2.1 Competitive Advantage
The understanding of what contributes to the competitive success of companies and what can be
considered as competitive advantage has received many definitions. The present competitive
environment has been defined as containing discontinuous change in demand, competitors,
technology, and regulation (Eisenhardt & Bourgeois, 1988), knowledge intensity, positive
feedback industries (Hitt & Bettis, 1995), globalization (Hitt et al., 1998), and hypercompetition
(D’Aveni 1995, 1999). The result is a competitive landscape described by strategic
discontinuities, blurring of industries, short product life cycles, high levels of uncertainty, and
stiff competition (Hitt & Bettis, 1995). Despite this complexity, we define competitiveness
according to D’Cruz and Rugman (1992) as the ability to design, produce, and or market
products superior to those offered by competitors, considering the price and the non-price
qualities; and Barney (1991) as a company having a competitive advantage when they are able
to implement a strategy that creates value not simultaneously implemented by any competitor,
and a sustainable competitive advantage when competitors are not able to duplicate the strategy.
2.1.1 Generic Strategies
Porter (1985) introduced the generic strategies— strategic scope and competitive advantage—
defined along two dimensions illustrated in figure 2.

Figure 2: The generic product strategies (Porter, 1985)
Competitive advantage defined the two basic advantages for companies: lower cost or
differentiation. Customer value can be produced by lower costs leading to a cost leadership, or
concentration on providing value by features and products that are perceived as unique through

differentiation. There is, however, no generalization of what constitutes differentiation, other
than that the products are not exact copies of each other in relation to the price and all non-price
qualities (Porter, 1985).
Value chain analysis is a general tool that can be used to analyze the general cost and value
drivers of company operations (figure 3) to maximize value and minimize costs. (Porter, 1985)
Figure 3: Model of value chain analysis (Porter, 1985)
Porter (1985) identified ten cost drivers including areas such as economies of scale, linking
among activities, timing of market entry, and degree of vertical integration impacting
competitiveness. By controlling these cost drivers or reconfiguring the value chain companies
can develop competitive advantages.
2.1.2 Industry Competition
The industrial organization (I/O) model (Ansoff, 1965; Andrews, 1971) and five forces theory
(Porter 1980, 1981, 1985; Teece 1984) suggest that firms obtain advantages by exploiting their
internal strengths, through responding to the environment while neutralizing threats and
weaknesses, and impacting the forces that dictate profitability and advantages of a defined
industry. These forces are shown in the figure 4.
Figure 4: The five industry forces impacting competition (Porter, 1985)
![Page 13: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/13.jpg)

The aim of a company is to through its actions maintain an ideal industry structure, e.g. low
supplier and buyer power, high entry barriers, and low rivalry to create the largest possible
profit. These models however make assumptions which have later been criticized. Barney
(1986, 1991) has pointed out that the resource homogeneity (Porter, 1981; Rummelt, 1984)
among industry participants, stable industry barriers, and the high mobility of resources (Barney
1986) don’t apply to competition now and therefore the model is not directly applicable
anymore.
More importantly, value chain analysis can be extended to include the whole external industry
value system that comprises of all the upstream and downstream companies, thus the whole
industry can be seen as an interconnected chain (Porter, 1998). Value is created by the
interaction of different stakeholders within the system and therefore competitiveness is
expanded to include the co-operation of the companies and not only the position and functions
of a single company (Brooks, 1997). The key task in a value system is to reconfigure so as to
create new sources of value and find a better fit between the created value and customers
(Normann & Ramirez, 1993). The level of direct control or ownership of the companies’ value
chain upstream inputs or downstream outputs is vertical integration. This can be e.g. ownership
of upstream raw material manufacturing or distribution channel ownership for a product
integrator. Vertical integration can lead to advantages in cost reduction through control and
reduced transaction costs, entry barriers for competition, and improved chain coordination to
increase customer value. Transaction costs are the costs caused by trading with others besides
the price (Carlton & Perloff, 1994). They include searching for the best offerings, contract
negotiations, and enforcing agreements. In general, these costs are high when there are a large
number of companies offering a service resulting in searching costs, and when uncertainty is
high due to changing market demands or specialized requirements impacting the need of
contractual and enforcing costs.
2.1.3 Firm Competitiveness
Firm competitiveness resulting from a company’s internal characteristic has as well inspired a
variety of theories and definitions. Prahalad and Hamel (1990, 1994) have proposed that in the
long run core competencies are the source of competitive advantages. These competencies—
integrated bundles of resources, skills aptituded, or technologies—are the specific things
companies excel at, and they provide the ability to build at lower cost and more rapidly than
competitors. These competencies must fulfill three criteria—ability to produce customer value,
competitive uniqueness, and extendibility—to be considered as core competencies. Some

examples can be enhanced abilities in miniaturization, technological experience, or even the
management of logistics channels. Companies’ products and portfolios should be based on their
respective core competencies to maximize the effect of these rare capabilities and leverage the
same competitive advantages in a wide range of markets.
The resource-based view combines the external competitive components (industry structure)
with the internal competitive components (firm competencies). Barney (1991) and Peteraf
(1993) define the resource-based view of the firm as a collection of resources and a set of
functions to utilize these resources as competitive advantages. The definition is based on the
assumption that a firm’s internal environment is critical for competition (Barney, 1991; Peteraf,
1993). The model assumes that resources within an industry can be heterogeneous and that these
resources are not perfectly mobile across companies (Barney, 1991). The resources can include
for example assets, organizational processes, technology knowledge, contacts, and personnel
(Barney, 1991; Porter, 1981; Peteraf, 1993) that are controlled by the firm and can be used to
improve efficiency. The view introduces four theoretical attributes that can be thought of as
empirical indicators of the ability of a certain resource to generate sustainable competitive
advantages: valuable, rare, imperfectly imitable, and substitutability. This is summarized in the
following framework (Figure 5).
Figure 5: VRIN framework for resource-based view (Barney, 1991)
From the resource-based view, a similar model has evolved called knowledge-based view. This
view refers to heterogeneous knowledge bases as the single most important factor in
competitiveness (Kogut & Zander, 1993; Grant, 1996). Companies can integrate the knowledge
of individuals to attain better performance (Grant, 1996), which can be done through creating,
storing, and applying knowledge (Spender, 1996).
The dynamic capabilities theory is as well an extension of the resource-based view, but it
focuses heavily on how the internal and external environment are matched together. Teece and
colleagues (1997) and Eisenhardt and Martin (2000) define dynamic capabilities as “processes
![Page 15: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/15.jpg)

15
that use resources—specifically the processes to integrate, reconfigure, gain, and release
resources—to match and even create market change”. Identifiable examples of dynamic
capabilities (Eisenhardt & Martin, 2000) are the integration of resources in product development
routines (Helfat & Raubitschek, 2000), reconfiguration of resources within transfer processes
(Hansen, 1999; Szulanski, 1996), and gaining and creating resources in routines like alliancing
(Gulati, 1999; Zollo & Singh, 1998). Competitiveness is therefore created through the constant
process of acquiring, integrating, reconfiguring, releasing, and restructuring resources
(Eisenhardt & Martin, 2000).
2.1.4 Miscellaneous Theories & Definitions
Social capital theory proposes that competitiveness can be affected by the acquirement of social
relationships. Bourdies and Wacquants (1992) define social capital as standing for “the sum of
resources, actual or virtual, that accrue to an individual or group by virtue of possessing a
durable network of more or less institutionalized relationship of mutual acquaintances and
recognition”. A relationship that provides access to physical resources can be considered a
competitive advantage (Nahapiet & Ghoshal, 1998). This rational is based on the three
categories offered by Lin (1999): relationships facilitate the flow of information giving
companies easy and low cost access to information hard to acquire; network participants may be
able to exert control over others; and social credentials may tie the parties of a network to each
other reinforcing the network from external access. Research has measured social capital by
valuing the assets embedded in the network and by studying the degree of the ties between
participants. Both of these approaches have been able to prove the relevance of social capital in
acquiring benefits from social networks (Lin, 1999).
In the dynamic competitive environment the advantage from moving first is considered an
important phenomenon. A first-mover can be defined as “an organization, which is first to
employ a particular strategy within a context of a specified scope” (Zahra et al., 1995). The
first-mover advantage has been proposed as the ability to earn positive economic profits
compared to followers resulting from e.g. leadership in product or technology development,
preemption of assets, buyer and supplier switching costs, or technology standardization
(Lieberman & Montgomery, 1988; Porter, 1985; Zahra et al., 1995). First-movers can as well
face disadvantages in the form of late-comers ability to free-ride on their investments, market
uncertainty, technological discontinuities, and incumbent inertia (Lieberman & Montgomery,
1988, 1998; Zahra et al., 1995; Makadok, 1998). The experience curve is a result of the first-
movers advantage (Lieberman & Montgomery, 1988), for as companies continue to perform a
![Page 16: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/16.jpg)

task, the cost of it lowers. As the cumulative volume doubles, value added costs tend to fall by a
constant percentage (Figure 6). This advantage can be sustained if the gained process or
production advantage can be kept proprietary or otherwise away from the knowledge of
competition (Ghemawat, 1985).
Figure 6: The impact of experience on the cost of production (Adapted from Lieberman, 1987)
To understand the impact of radical innovations, Christensen (1997) introduced the theory of
disruptive technologies. As incumbents concentrate on incremental innovation, time and again,
disruptive technologies emerge that are typically cheaper, simpler, or different in some other
key category. These technologies enter the market from the low-end. As the technologies
mature and achieve the necessary performance, they ultimately take over the market, replace the
prior technology as illustrated in figure 7, and restructure the whole industry.
Figure 7: Impact of disruptive technologies on the incumbent technology (adapted from
Christensen, 1997)
2.2 Software Product Approach
Software products involve distinct factors and characteristics impacting competitiveness. The
purpose of this chapter is to describe these competitive factors and assess their competitive
implications.
![Page 17: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/17.jpg)

2.2.1 Software Product Characteristics
Competition in software products can be described as including short product life cycles,
intense competition, uncertainty, technological discontinuity, changing and growing customer
requirements, and globalization (Cusumano, 2004; Hyvönen, 2003; Hitt et al., 1998; Hitt &
Bettis, 1995; Baker, 1998). As a result, companies have had to react with an emphasis on
innovation, efficient and improved production, faster time to market, and information sharing
and learning (Cusumano, 2004; Athey, 1998; Hoch et al., 1999; Hersleb & Moitra, 2001). The
value system of production is complex because of the range of industries it impacts, but we can
make a simplification according to Hyvönen (2003). The general value system consists of
upstream component producers and outsourcing suppliers delivering software to integrators who
then distribute products downstream.
Software as a product can be described as an information good because it is intangible (Shapiro
& Varian, 1999). This leads to costly initial production, and high fixed costs, but once ready,
reproducing is essentially free. These result in the marginal costs of production moving close to
zero and the marginal revenues growing in pace with the market share, as seen in figure 8.
Figure 8: Development of the marginal cost of software production (Adapted from Shapiro &
Varian, 1999)
Software being an intangible good also leads to issues in differentiating products because
copying is easy (Hoch et al., 1999). Comparing the processes of development and production,
the distinction with manufacturing industries is substantial. Highly knowledge-intensive
development (Armour, 2000; Shapiro & Varian, 1999; Hoch et al., 1999) implies that the most
critical parts are not only processes, but the experience and knowledge of personnel and
companies (Cusumano, 2004; Armour, 2000). Because of the importance of human capital,
there is no way to automate the development process (Hoch et al., 1999).
![Page 18: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/18.jpg)

To understand the investment in software product related R&D, the expenditure by some of the
top companies during the year 2004 is presented in figure 9.
Figure 9: Examples of the R&D expenditure by some of the top companies, related to software
production (Technology Review, 2005)
The R&D expenditure of these companies’ sums up to an investment of over $32 billion,
however, a part of it is related to hardware development. Similar R&D expenditures in software
intensive industries during 2004 include the telecommunication sector investment of over $26
billion and electronics and consumer electronics industry’s expenditure of over $30 billion.
2.2.2 Competitive Implications
The characteristics of software as a product lead to the following distinct factors impacting
competitiveness.
For product businesses intellectual property rights (IPR) are a major component of
competitiveness (Nambisan, 2001). IPR is defined as the legal and exclusive ownership of
distinct technology implementations. Companies can use different forms—trade secret, patent,
copyright, and trademark—of IPR to protect their investment and differentiation from
competitors. However, this does not totally solve the issues of copying, as IPR can be
circumvented with non-infringing yet similar implementations. The importance of IPR can be
seen through the enormous patent holdings of companies such as IBM or Microsoft or hardware
vendors such as Nokia. (Nambisan, 2001; Hall, 2003; Messerschmitt & Szyperski, 2003)
Network externalities are a common factor in software related products, as they can form a
virtual network through shared characteristics or functionality. The externalities arise if there is
a complementary relation between the adaptations of the product by different users, impacting
![Page 19: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/19.jpg)

19
the incentive for new users to also adopt the product. Typical examples are communication
products, operating systems, and products that store information. Metcalf’s law proposes an
estimation that the value of a network to one user can be proportional to the number of the other
users. Particular network externalities in software related product markets can be split into two
categories: direct network externalities arise if utility from using a good is directly increased
when other people use this good; and indirect network externalities arise from the availability
and the price of complementary goods. The bigger the network is, the more there are
complementary products and services, and therefore the lower the prices are. If network
externalities are strong, then each user wants to adopt the product which has the biggest network
to appropriate as much value as possible resulting in a positive feedback system or “virtuous
cycle”. (Shapiro & Varian, 1999)
Customers and suppliers are also prone to lock-in. As users and suppliers invest in durable
systems, products, and competence, they acquire high switching costs and it is easier for them to
continue relying on the same product. Lock-in can be introduced by e.g. contractual
commitments, training, learning, and the formation of experience and information. Through
product lock-in, installed user bases are a valued part of competitiveness, and managing and
leveraging lock-in has been a key contributor to the success of companies. (Shapiro & Varian,
1999; Baker, 1998; Nambisan, 2001)
De facto standards are an influential part of product businesses as these are the technologies
that achieve an accepted dominant design in the market. They can form a substantial element in
competition, as products adhering to the de facto standard have a higher chance of succeeding in
the market. This influences costs as products must adhere to the standards, but can also
constitute competitive advantages if companies are able to create and control them. Competition
in many products markets has moved towards competition between systems and not individual
products, where standards have a key role in compatibility. For product companies it is of the
utmost importance to be a part of the de facto standard system and have a relatively good
position in this system. (Shapiro & Varian, 1999; Baker, 1998)
Competitiveness and entry barriers are also based on high initial and continuous investments in
R&D, customer feedback and knowledge, brand recognition, technology lead, and distribution
channel creation (Cusumano, 2004; Nambisan, 2001; Messerschmitt & Szypenski, 2003).

2.2.3 Software Layers and Platforms
Software generally consists of layers and modular components, which serve each other and
comprise a total system (Messerschimtt & Szypenski, 2003). A generalization of the layered
form of software can be presented as figure 10.

Figure 10: General layered form of software products (Adapted from Messerschmitt & Szypenski,
2003)
The layered structure and the nature of software lead to enhanced commoditization of
technologies over time. This is a result from copying of features, stiff competition, and software
characteristics. The proven technologies and components are common across competition and
cannot therefore function as differentiation. This leads to commodity software that we define as
components that cannot be used to differentiate products, but are still necessary for a complete
product. For companies who have invested heavily and continue to invest in these technologies
or components, commoditization is a substantial threat to their business and a continuous issue.
(Cusumano, 2004; Shapiro & Varian, 1999; Augustin et al., 2002)
A recent strategic approach to product businesses, due to the layered form of software, has been
the concept of product platforms or product families. This can be associated to either a software
base that is used to produce derivate products (Meyer & Selinger, 1998) or a platform driving an
ecosystem of products (Gawer & Cusumano, 2002). A product platform can be defined as a set
of subsystems and interfaces that form a common structure from which a stream of derivative
products can be efficiently developed and produced (Meyer & Selinger, 1998; Meyer & Mugge,
2001). This has improved competitiveness with the ability to cut costs, speed up development,
lower risk, and target distinct markets with differentiated products and more precision
(Robertson & Ulrich, 1998; Meyer & Zack, 1996; Meyer & Selinger, 1998).
Gawer and Cusumano (2002) recognized the advantage of driving an ecosystem and enabling
innovation on the complementary applications of the platform, or the components and
subsystems included in the platform itself. Companies can integrate the external innovation
![Page 21: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/21.jpg)

21
ability in a precise scale to their products. This enables the company to expand the market by
leveraging external efforts. The maximum benefit is derived if the complementary product
market is commoditized (Shapiro & Varian, 1999), as this drives up the value of the platform.
2.3 Software as Production Process
The purpose of this chapter is to describe the production process of software and illustrate the
competitive implications.
2.3.1 Software Production Characteristics
The production process can be a defining firm-level activity in company competitiveness.
Software as a logical element is clearly distinguished from producing hardware, because of its
knowledge intensiveness and complexity (Pressman, 2004; Brooks, 1987). It is more of a rule
than an exception that software productions are delayed, overrun cost estimates, produce low
quality, and fail to fulfill customer requirements (Standish Group, 1995; Pressman, 2004;
Haikala, 2001).
Because of these issues, various production processes have been defined as the “establishment
and use of sound principles in order to obtain economically software that is reliable and works
efficiently” (Pressman, 2004). The goal of software processes is simply to create an advantage in
the production process. The process can be broken down to three generic phases to describe the
whole life cycle: definition (system analysis, project planning, and requirement analysis),
development (software design, coding, and software testing), and maintenance (change,
correction, adaptation, and enhancement) (Sommerville, 2001; Pressman, 2004).
2.3.2 Competitive Implications
In spite of the different process models, in practice all of them suffer from the same challenges.
For competitiveness, the keys for production processes are reducing time-to-market and cost of
software, producing feature-rich and high quality products, and controlling the high risk
resulting from sunk costs and customer need uncertainty (Poulin et al., 1993).
The software life cycle cost consists of all the expenses accumulated from the start of the
development until the end of maintenance. This can be illustrated by the figure 11.
![Page 22: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/22.jpg)

Figure 11: Cost of software during whole life cycle (Haikala, 2001)
The figure only illustrates how much of the resources are spent on the certain part of the life
cycle, but it doesn’t explain any reasons for these commitments. Boehm (1988) divided the
distribution of costs into four groups: development and rework; code and documentation; labor
and capital; and by phase and activity. A notable part in the continuous cost of software is the
effect rework has on it. This is needed to compensate for bad design, to fix errors in the code, or
not satisfying the customer needs (Pressman, 2004; Denning, 1992). Labor-costs are a key part
because of the nature of software production and the huge gap between the productivity of the
best and average developers, ranging to even 100 fold differences (Boehm, 1981). By phase and
activity, the most cost intensive parts are testing and maintenance, which belong to the end of
the software products life cycle. To understand the cost of software, Boehm (1988) also
presented the value chain of development (figure 12).
Figure 12: Software production value chain (Boehm, 1988)
![Page 23: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/23.jpg)

It is evident that the most important part of software costs is introduced during the operations
part, which consists of 80% of the value chain, but a fairly small part of this is direct code
implementation. (Boehm, 1988; Haikala, 2001; Pressman, 2004)
Development time is defined by the size of the product and the resources available to complete
it. Size can be measured by methods including source lines of code (SLOC), or effort in man
years or hours (Armour, 2002). Dividing the size, regardless of the metric, with the resources
results in the time or effort development takes. However, due to the nature of software, this
relation is non-linear, as tripling the amount of resources does not cut down the time into one
third as seen in figure 13 (Armour, 2002).
Figure 13: Effort-time curve of software production (Armour, 2002)
2.4 Open Source Software
OSS is software distributed under open source licenses making the source code of executables
available for redistribution and modifications. The purpose of this section is to examine OSS
based on three characteristics —licensing, development model, and commercial OSS—and to
examine the disruptive impact and opportunity OSS creates.
2.4.1 Open Source Licensing
Copyright protects the original software creation and derivative work by granting the creator the
exclusive right to control the resulting work and enables the licensing model. The owner of the
copyright is the author, or the company whose resources were used to create the software.
However, only written code is protected, not technical innovations or algorithms. (Fink, 2003;
Ruffin & Ebert, 2004)
The main difference between OSS and proprietary software is the licensing model. In licensing
there are two important roles: the licensor as the owner or distributor of the software and the
![Page 24: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/24.jpg)

24
licensee as the software’s user either as an end-user or another developer. Typically the licensee
has to buy the license from the licensor to gain the right to use the program. These licenses
usually deny the right to distribute, modify, or re-engineer the software. However, the open
source definition states that you can freely use, modify, or distribute the software, if you attain
to the restrictions of the open source status (Open Source Iniative, 2002).
2.4.1.1 Open Source Licenses
OSS licensing tries to make software free and ensure that the source code is available. Some
licenses introduced later on have, however, moved away from the original intention, and do not
force people to make the source available, such one license is the Netscape Public License
(NPL). Software can also be licensed under more than one license, which leads to the licensee
choosing the license terms they prefer, with typically an option between an OSS license and a
commercial license. (Fink, 2003)
The most widely used open source license is the GNU General Public License (GPL). The GPL
requires that every modification made to software under GPL and distributed, must also be
available under the same license. This includes all derivative work, so it is enough if software is
linked to code licensed under GPL to cause this “viral” effect, which can also be called the
“copyleft” attribute. It does not, however, mean that if there is closed code running in a product,
which also includes code under GPL that all the code must be made available under the same
license. (Fink, 2003; Capek et al., 2005)
The GNU Lesser General Public License (LGPL) is a lighter version of GPL. It does not
mandate the licensing of software that dynamically links to code under LGPL. This enables use
of the code under LGPL, without the problems of opening the source code of your own software
that links to it. However, direct modifications to software under LGPL must be published under
the same license. (Fink, 2003)
The open source initiative (OSI) has approved a total of 58 licenses as official OSS licenses.
The essential differences between these licenses are related to commercial usage and in what
ways and how widely it is allowed. The difference between some OSS licenses is illustrated in
the table 1 (Perens, 1999).
![Page 25: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/25.jpg)

2.4.1.2 Legal Risks and Challenges
For companies using OSS there are evident legal risks. OSS typically has many authors and is
developed in a collaborative and informal manner by people with no legal relationship. It is
nearly impossible to later on know reliably whether the person granting a license has the right to
do so. This complexity may cause unintentional copyright or patent infringements. The issue
exists with all software, but with OSS it is much easier to detect the infringement as an external
and it is more likely to happen. (Capek et al., 2005; Ruffin & Ebert, 2004)
The proliferation of OSS licenses is also a problem. None of the licenses have actually been
scrutinized in court and the legal robustness and completeness vary, e.g. licenses are unclear on
their relation with IPR. There are also cases of software projects mixing different licensing
together that are not compatible, resulting in legally faulty licensing that would in all likelihood
be hard or impossible to interpret in court. (Capek et al., 2005)
2.4.2 Open Source Development
The open source community is an international group of people contributing in a mixture of
ways to open source projects. The size of the community has grown significantly with, for
example, one open source repository Sourceforge hosting over 60,000 projects with around
620,000 registered developers in 2003 (Bonaccorssi & Rossi, 2004) and the number growing to
over 1.3 million developers and 115,000 projects during 2006 (Sourceforge). The community

has produced diverse software such as Apache, Sendmail, BIND; scripting languages PERL,
Python, PHP; operating system components Linux Kernel, Gnome, KDE; and applications like
Mozilla, GIMP, and GNU software (Benussi, 2005; Schweik & Semenov, 2003; Kogut &
Metiu, 2001).
There is no clear definition of a community participant as the variety goes from unemployed
hackers to people working full time in companies, working on OSS either as a part of their job,
or in their own free time. (Feller & Fitzgerald, 2000; Pavlicek, 2000; Lerner & Tirole, 2002)
The motivation of these developers can be split between extrinsic, i.e. related to indirect
satisfactions, and intrinsic, i.e. directly filling the needs of developers. Extrinsic motivations
include gaining a reputation among other developers (Dalle & David, 2004; Lerner & Tirole,
2001); enhancing career opportunities by proving development skills (Lerner & Tirole, 2004);
learning new skills and technologies (Krogh et al., 2003; Ye & Kishida, 2003); gaining
contributions to development projects (Raymond, 1999); fulfilling technical problems (Feller &
Fitzgerald, 2002); direct monetary rewards (Lerner & Tirole 2000; Hertel et al., 2003); and
because of low opportunity costs of working on OSS, as developers have nothing to gain from
keeping their work proprietary (Bonaccorsi & Rossi, 2003a). The general intrinsic motivators
are enjoying the creation of something (Lakhani & Wolf, 2003); altruism resulting in
satisfaction from helping others, and battling against proprietary software companies
(Raymond, 1999).
2.4.2.1 Development Principles
There is no official model or process of development in the open source community. However,
it can be described regarding characteristics related to the organization, development process,
and control of projects. (Feller & Fitzgerald, 2002)
Unlike any formal organizations, open source communities have zero formal timelines,
deliverables, or requirements. The collaboration is arranged through the Internet with tools to
help the information flow and to ease the development process. The decision making of
collaboration follows a decentralized model, where the core maintainers and developers have
the most influence over the decisions. (Mockus et al., 2000; Feller & Fitzgerald, 2002; Fink,
2003; Krogh, 2003)
The development process is highly parallel with developers working on small components of
larger subsystems. Parallel development makes it possible for developers to collaborate in a

distributed manner and utilize a rapid release pattern. The intention is to keep the incremental
process of development going on as fast as possible and to release new versions every time
software has been modified. Because of this rapid release cycle, the community can use rigorous
peer review. Developers and users continuously review the work of others, which can enhance
the development process to produce faster evolving programs. The collaborative model also
enables the intellectual knowledge of thousands of developers globally to be combined. (Feller
& Fitzgerald, 2002; Mockus et al., 2000; O’Reilly, 1999; Raymond, 1999)
2.4.2.2 Impact of Development
According to several authors (Feller & Fitzgerald, 2000; O’Reilly, 1999; Scacchi, 2002) the
open source development model produces better quality, faster growth, more creativity, and
cheaper software, than closed-source production.
Mockus et al., (2000, 2002), Jorgenssen (2001), Ding-Tong & Bieman (2004), Paulson et al.,
(2004), MacCormack et al., (2005), Stamelos et al., (2002), Godfrey and Tu (2000), Koch
(2005), and Kuan (2000) have argued and provided empirical proof from various projects that
OSS included fewer defects than proprietary software, the speed at which found defects are
fixed is substantially faster, the software evolves faster, and is of high modularity. To give
perspective into the growth of open source systems Amor-Iglesias et al., (2005) measured
Debian as one of the largest software systems in the world, despite its young age, at 5 times the
size of Windows XP. Stamelos et al., (2002), Paulson et al., (2004), and Schach et al., (2002)
however have found contradicting proof that OSS is lagging behind industry quality standards
and the speed of development is in no way faster than closed software development.
The open source development has also received direct critique. Caoiluppi et al., (2003) and
Healy and Schussman (2003) have noticed that the majority of projects are small, with 50%
consisting of only one or two developers. This indicates that developers are a scarce resource
and only the most successful projects gain a critical mass. Some authors have also accused OSS
of lacking in usability and customer focus. Nichols & Twidale (2003), Nichols et al., (2001),
and Levesque (2004) have argued that there is a usability problem due to developers
concentrating only on the needs of developers. Security of open source software has as well
been of concern to the software industry because of the open approach (Levy, 2000; Viega,
2000). Payne (2002) contradicted the arguments by stating that OSS can be more secure due to
the heavy peer-review and the speed that defects are fixed with.
![Page 28: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/28.jpg)

Scacchi (2002) has summarized that the development model is not an irrational version of the
traditional approach, but instead a private-collective approach to development, which can
provide better results in the right environment. The advantage in cheaper, faster, and better
development is dependant on the target product, used tools, and if the information needed is
well suited for the OSS process.
2.4.2.3 Innovation Model
The innovation model of OSS has been proposed as a novel “private-collective” model (Von
Hippel & Krogh, 2003; McKelvey, 2001). The model is based on private resources invested into
a collective pool, unlike the prevailing models where either, parties invest to gain commercial
returns or public goods produce innovation due to a forced common innovation pool. The
private-collective model is argued to be more efficient, to produce valuable innovations for
smaller costs, and to achieve more useful results than the prevailing models. Users as innovators
are an important part of the proposed model according to Von Hippel (2001). Open source
fulfills the conditions—incentives for users to innovate, to reveal innovations freely, and
innovation diffusion by users—that are necessary for such innovation to take place. Klincewicz
(2005) has, however, challenged the innovativeness of open source development by arguing that
the mass of OSS projects exhibit low levels of technical novelty.
2.4.3 Commercial Open Source
The emergence of OSS to a market populated by commercial software can have an impact on
the value of products. Value is derived from the features, and this value goes down over time
because the features become common among products. As OSS enters a market, the speed at
which the devaluation happens, can be in relation to the features included in the OSS (Figure
14).
Figure 14: OSS impact on the value of commercial software (Fink, 2003)
![Page 29: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/29.jpg)

29
As a result, the time over which value is derived can be shortened and the revenues gathered
from the product lowered. In practice this can mean that software becomes a commodity as fast
as the community is able to produce an OSS substitute. This would imply that from a
commercial viewpoint the most critical impact of OSS is commoditization (Fink, 2003).
However, it is still not completely clear how profit and non-profit production interact. Khalak
(2000) and Gaudeul (2003) proposed that in despite of the characteristics of OSS, the impact on
commercial software is dependant on the software’s ability to gather a critical mass of the
customer base; OSS includes a wide range of shortcomings compared to commercial products;
and customers do not judge products only on their monetary cost.
As evidence of the commodity status of OSS, the business models built around it concentrate on
gaining revenues from complementary products. These business models gather revenues from
support, custom development, training, and consulting or enabling hardware sales, e.g. the
models of Red Hat Software, O’Reilly, and Cygnus solutions (Fink, 2003; Henkel, 2004).
2.4.3.1 Recent Open Source Diffusion by Commercial Parties
As a result of the diffusion of OSS utilization by companies and contributions to open source
projects, the investment in OSS has been growing steadily. Examples in 2005 include Sun
Microsystems (2005) licensing their Solaris 10 operating system under an open source license,
IBM opening 500 patents for free utilization with OSS (IBM, 2005), and committing 100
million dollars to OSS (Vunet, 2005). Hewlett-Packard has also funded foundations such as the
Eclipse Foundation, Gentoo Linux, Gnome Foundation, Open Source Development Labs
(OSDL, 2006), and KDE and contributed to projects including Apache, Debian, Handhelds.org,
and Samba amongst others. During 2005, there was also a movement to solidify OSS utilization
with industry wide collaboration resulting in Alliances like SCOPE including the companies
Nokia, Ericsson, Siemens, Motorola, and NEC collaborating to encourage open source
utilization, and IBM, Novell, Philips, Red Hat Inc., and Sony forming a patent-holding company
to further enhance open source development.
2.4.3.2 Commercial Motivation Drivers
Commercial parties have a range of business drivers to be involved with the OSS community.
OSS especially offers cost and time related opportunities. Madanmohan and De’ (2004) propose
that companies leverage OSS to gain faster access to markets. The use of open source
components considerably shortens the product development time. Companies see similar
advantages in leveraging the OSS code base to cut down the costs of development (Fink, 2003;
![Page 30: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/30.jpg)

Goldman & Gabriel, 2005; Aoki et al., 2001). Dahlander (2004) also proposed that an incentive
is the ability to leverage the inventive and R&D actions of the community. This also enables
the companies to access the work of others involved with OSS. West (2003) recognized that
firms release source code in order to get their product widely adopted, and therefore as
adaptation increases they gain a better chance of attracting developers and can accelerate the
technological development of their products. Cutting into the cost of maintenance is also
possible by shifting the cost to the community (West, 2003; Hawkins, 2002).
Companies see OSS also as a tool to gain benefits not directly related to cost or time. Lerner and
Tirole (2002) proposed that parties value the opportunity to enhance the ability of OSS to
reduce the market shares of dominant software firms, and therefore establish independence
from price and licensing policies. Fink (2003) presented the need of companies for talented
resources. This has pushed companies to stay involved in OSS as the developers have the
knowledge of the open source programs and could be valuable if hired. Feller and Fitzgerald
(2002) propose involvement can be used as a way to improve the image of the corporation and
the brand and make a better impression with customers and investors. Osterloh et al., (2002)
also proposed that companies are ultimately involved with OSS only to keep the active
cooperative relationship alive. They see the community as an important part of the future of the
industry and therefore they invest resources in interacting with the community.
A third category of business opportunities is the ability to impact competition. Goldman and
Gabriel (2005) recognized the ability of OSS to act as a tool to form standards. Open code and
a wide circulation of the software are effective forces to form a standard. Standardization with
OSS is less likely to suffer from politics, and the decision making is more likely to center on
technological issues. Some companies also take part in OSS activities to commoditize parts of
commercial solutions (West, 2003; Wichmann, 2002). By providing no-cost offerings they
force the competition to play a commodity game. This is beneficial for the companies that are
on a higher layer of the software stack and can differentiate or gain revenues there.
2.4.3.3 Commercial Involvement and Openness Strategies
The ability to leverage the community to appropriate value is dependant on the strategic
approach the company takes to interacting, managing, and utilizing the available resources
(Dahlander & Magnusson, 2005; Bonaccorsi & Rossi, 2003b). Dahlander and Magnusson
(2005) and Madanmohan and Krishnamurthy (2005) have proposed a three-way categorization
to the different involvement approaches companies can take to OSS utilization.
![Page 31: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/31.jpg)

The lightweight approach has been to directly tap into the OSS asset and utilize this either
directly or as internally modified in products. This approach includes no continuous effort to
contribute work back to the community and concentrates only on the short-term benefit.
The second category is implemented through a more commensalistic approach. The
commercial party takes and utilizes OSS, and tries to keep the modifications of software
minimal to stay in synchronization with the community. However, the involvement is kept as
small as possible with very little effort going back to the community, and the goal is not to
benefit the community in any way, just to avoid harming it from continuing work. Because of
the synchronization with the community, the company can appropriate benefits in a continuous
manner, but have very little ability to control or impact the development.
The third category is based on actively collaborating to and participating in the work the
community does. With this approach companies typically have direct involvement with the
community and continuously contribute by sponsoring, contributing software, or even
developing communities around their own software. The OSS asset can be considered as an
extension of the companies’ resources and result in the most efficient development.
Companies can also follow different structural openness strategies that impact their ability to
benefit from OSS. These different strategies can take three forms based on the work of West
(2003). Companies can decide either to make openly available layers of the product or to
concentrate on utilizing open source licenses for distinct technology components. Opening
layers of the product results in the company enabling efficient development in that area, but also
possibly loosing control of it. Again, the strategy to make available distinct components retains
a higher level of overall control, but benefits less from development. A third possible structural
approach is to utilize the openly available architecture provided by the OSS community and
base R&D on it. These strategic approaches can be illustrated with the following figure 15.
Figure 15: Software product categorizing according to level of openness and opened parts (West,
2003)

2.4.3.4 Challenges of Corporate Open Source
Collaborating and integrating the open source development into commercial operations poses
problems and issues with defining the community, communication, expectations, and typical
OSS practices.
Long (2003) and Dahlander and Magnusson (2005) identified various challenges companies
faced when managing open source communities and projects. Authority structure was the most
significant problem identified. Companies usually have the last say in decisions regarding
development, code acceptance, and roadmap. This breaks the collaborative model, which causes
friction between the community and the company. Another problem existed with property
rights. Companies usually enforce some kind of licensing model on the development project,
which again goes against the principles of the community. Often developers voice harsh
criticism on issues regarding copyright ownership and licenses, and due to the discontent stop
developing for the project. The third major challenge was community building. This is because
the effort needed to build the community is often neglected. The norms and values of the
community are also a challenge. These protect the community from depletion and are usually in
conflict with the norms of a company. Aligning the nature of the work and getting acceptance to
use the software for commercial purposes also causes issues as commercial interests differ a
good deal from the communities’ interests. If these challenges are not managed, companies lose
the advantages possibly gained through the OSS development activity.
Many authors (Bonaccorsi & Rossi, 2003b; Osterloh et al., 2002) have proposed that the most
significant issue for commercial parties is adhering to the open source norms and rules. The
culture follows a certain set of norms including trust, collaborative thinking, and sharing of
innovations, which must be followed to be accepted as a part of the community. Exploiting the
existing pool of software more than you contribute back still enlarges the pool and raises the
level of motivation for open source producers. It seems that for accepted entrance, the level of
effort can be limited to the minimum and still it is acceptable from the communities’ viewpoint
(Bonaccorssi & Rossi, 2004).
An important challenge is also unintentional information revealing. Companies working with
OSS can accidentally open source software, which includes important IPR, and which is thus
revealed. The copyleft attribute of some OSS licenses can also enforce this revealing, when
code is used in combination with these licenses. (Fink, 2003; Ruffin & Ebert, 2004)
![Page 33: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/33.jpg)

2.4.3.5 Strategic Disadvantages of Open Source Utilization
As companies choose to utilize OSS as a part of their product strategy, they are confronted with
strategic disadvantages due to the open availability of the software and the licensing terms of
copyleft licenses mandating openness.
Foremost, this results in the loss of IPR as protection from competition. Both software coming
from the community and made available under open source licenses are openly available. This
implies that the software alone can provide no competitive advantage, it looses most of its sale
value, and there is a risk of loosing the development control. Business models concentrating on
complementary products, bundled with software, are as well subject to disadvantages due to
competition providing the complement with less cost or higher quality. (Henkel, 2004)
Judging the loss of competitive protection and advantage is, however, not directly possible, as it
is dependant on the degree of competition, relation of the software to the external domain,
availability of alternatives, and the level of specifity of the software for the company (Henkel,
2003; Harhoff et al., 2003; Johnson, 2004). The external environment evidently defines the
competitive implications of utilizing OSS. As certain IPR is made openly available and the
competitive value of it is neutralized, the value of specific IPR is inflated (Goldman & Gabriel,
2005). This impact of collaborative development by commercial parties has been realized by the
Embedded Linux producers, and lead to an environment where differentiation is hard and the
value of specific IPR has grown enormously.
2.4.3.6 Open Source in Products Theory
Literature has presented two generic strategies that work as the basis for utilizing OSS in
product development. Companies can choose to either bundle OSS with proprietary software or
dual license the products. Companies choosing to bundle the two types of software typically
make a distinction between the open source and the closed source part (Figure 16).
Figure 16: Generic product strategy for combining OSS and proprietary software (Pal &
Madanmohan, 2002)
![Page 34: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/34.jpg)

34
There is no rule to the ratio of open and closed source, but a higher open source ratio typically
signals more benefits but also stronger strategic disadvantages. (Pal & Madanmohan, 2002)
The second generic product strategy is based on dual licensing. In this setting, the commercial
party can continue to sell the software but they can also leverage the community effort to
develop it. If the software is licensed under an open source license, the licensee is typically
forced to license all derivate work under identical terms. The commercial company is therefore
able to maintain control of the commercial usage and development. This forces commercial
users of the software to pay royalties, so that they can keep products that have been modified or
bundled with proprietary software secret. However, dual licensing has certain constraints,
because it is impossible to leverage the effort of the community on a larger scale as software
must be initially self-developed. For third party contributions from the open source
development, the copyright must also either be assigned to the copyright holder or licensed
under terms that are broad enough to enable commercial and non-commercial usage. (Fink,
2003; Henkel, 2003)
2.5 Summary of Literature Review Findings
The goal of this section is to summarize the factors related to the industry level impact;
competitive opportunity resulting from OSS characteristics; and existing firm-level strategies.
2.5.1 Disruption and Maturity
The OSS asset has achieved a higher level of maturity and we can conclude that OSS is a
gradually strengthening industry wide disruption. The software industry is in a transition phase
with commercial parties increasingly recognizing, reacting to, and leveraging the opportunity
presented by this disruption. This happens through heterogeneous collaboration strategies,
defined as direct competitors adapting distinct strategies—full closed source, dual licensing,
direct utilization, or collaborative development—to leverage the OSS asset. The result also
creates a positive feedback system, further increasing the value and maturity of the OSS asset.
The maturation is evident in the diffusion of developers working on OSS, which is estimated at
over 1.3 million, and the dozens of commercial parties investing in the software asset. However,
OSS still exhibits the following identified limitations and characteristics: there is no single
defined development process or output of the development model; a large part of the projects
have only few contributors and do not incorporate the benefits of a strong collaborative
![Page 35: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/35.jpg)

35
development model; and the features of OSS concentrate on the infrastructure or middleware
layers and not the user interface (UI) or tested end-user solutions.
The characteristics and limitations break the impact into two groups. A part of the projects are
still inferior to commercial software, and the assumption of maturity is just an illusion brought
forth by some extremely successful products and the community evangelists. The second
category of mature or active OSS projects rival closed-source products in quality, growth, and
innovation and have a commoditizing impact on the value of software. Through this impact, it is
possible that layers of software stacks are devalued. For commercial usage OSS can only be
considered commodity software, as it doesn’t create customer value through differentiation, but
by matching quality at lower costs. We can conclude the important characteristic of OSS
impacting software product companies in the following table 2.

2.5.2 Firm-Level Strategies Model
As a consequence of the characteristics of OSS and software commoditization, companies can
apply different levels of external collaboration to match the external environment. This can be
presented relative to the level of differentiation software technologies can offer and the level of
![Page 36: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/36.jpg)

collaboration with external parties in R&D (Figure 17). The three strategies move from intra
company development, collaboration with gated OSS communities, to total openness.
Figure 17: Software development in relation to the domain of differentiation and external
collaboration (adapted from ITEA, 2003)
Collaborative R&D depending on the strategic approach brings benefits in the form of faster
access to markets, smaller initial and continuous investment in R&D, ability to interact with
experienced and talented resources, and a positive relationship with the community. This can
also impact competition with shorter technology life cycles, moving software faster to the
commodity level and impact the creation of de facto standards. However, collaborative R&D
also features problematic issues and disadvantages, e.g. collaboration between a commercial
party and the community is not trivial; OSS utilization causes challenges in the legal domain
because of a risk of infringing copyright or patents as well as putting the companies own IPR at
risk; and the reduced advantage and protection of IPR mitigates competitive advantages and
diminishes the effect of network externalities and lock-in.
This model works as the basis of the rationale for collaborative R&D. The company attempts to
balance collaborative R&D and its benefits in certain software areas, without risking their
competitiveness in the industry environment. The rationale for the high rate of collaboration can
be based on the level of competition and commoditization moving differentiating software to a
minor part of total products. It must be noted that commoditization in software is a complex
topic, and in some areas the assumption of non-differentiating software can be false, but for the
sake of the framework we make the assumption that the presented model is applicable.

3. COLLABORATIVE R&D FRAMEWORK
The goal of this chapter is to create a framework describing the impact of collaborative R&D on
competitiveness and detailing the firm-level strategies. The framework takes a top-down
approach by first presenting the impacts on competitiveness and then describing the firm-level
strategies to achieve them.
3.1 Relative Competitive Advantages
Resulting from collaborative R&D, companies can create relative advantages during the
transition phase of the industry. The advantages are relative, because they depend on the state
of the industry and competition exhibiting heterogeneous collaboration strategies.
Collaborative R&D can reconfigure the internal value chain and the whole value system of
product development to concentrate both the investments and competition to certain areas. The
result is a better configuration between the internal competencies of the company and their
match with the external environment. This is achieved through:
• Defining the value of software in relation to the industry environment;
• Reconfiguring and integrating the external development resources with collaborative
R&D in non-differentiating software; and
• Continuously managing the interface of non-differentiating and differentiating software.
Because of heterogeneous competencies, collaboration strategies, and common technologies in
different product markets, the reconfiguration can result in three relative advantages. Firstly, the
internal investment is concentrated on value creating software and processes resulting in
heightened efficiency. Secondly, collaboration moves software value to the OSS asset and
commoditization continuously impacts the value of software increasing the value of owned
competencies and technologies. Thirdly, the changed cost structure and commoditized software
enable the expansion of the scope of existing competencies to new markets with improved
efficiency. The OSS asset mitigates the differences between companies.
During the transition of the industry, early collaboration can lead to a first-mover advantage.
With the increasing value of the OSS asset and the previously defined relative advantages, it is
possible that part of the industry gradually moves to homogenous collaboration strategies.

Competing companies would utilize similar strategies and the same communities and
technologies from the OSS asset. This could lead to a reconfiguration of the forces impacting
the industry, e.g. OSS as the main supplier, entry barriers, substitutes, buyer power, and rivalry.
In the resulting industry, the state of the first-mover advantage from early utilization, pre-
emption of OSS resources, and maturing of collaboration processes, could lead to higher
benefits than late-comers can gain.
The evident limitation is that collaborative R&D does not directly impact the creation of
definable internal advantages in the form of resources or other holdings. It concentrates on
leveraging firm-level activities to gain the most value of existing or otherwise developed
competencies in relation to the industry environment.
We can summarize the advantages and their dependency on the industry phase in the following

3.2 Strategic Split Based on Software Value
To be able to leverage collaborative R&D, product software must be split into two strategic
areas based on the differentiating value. This is necessary because the areas follow different
firm-level strategies. This enables companies to manage the strategic disadvantages resulting
from collaborative R&D and gain the maximum benefit.
![Page 40: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/40.jpg)

3.2.1 Non-Differentiating Software
The firm-level strategies of non-differentiating software development aim at reconfiguring the
value chain. These strategies follow a specific form of collaboration and result in lower initial
and continuous investment, reduced transaction costs, creation of de facto standards, social
capital, and a first-mover advantage.
3.2.1.1 Collaboration and Value from Existing Communities
The form of collaboration with existing communities is considered upstream vertical
integration mostly based on informal relationships. The internal R&D is extended to be a part
of the external R&D with a continuous two-way flow of software, investment, and effort as
illustrated in the figure 18.

The flow back to the OSS asset is necessary to share the maintenance cost of software; initiate
the collaborative R&D on technologies not yet present in the OSS asset; and hasten the
commoditizing impact on the value of software.
Vertical integration to the upstream OSS asset does not only impact the initial and continuous
investment. As expected, through integration with the OSS asset, the commercial transaction
costs related to software development are reduced. The reduction can be seen in the ability to
utilize openly available development tools, directly interact with the original authors, and seek
highly competent resources, as well as the increased flexibility of not needing to depend on
certain software suppliers. These result in searching costs being considerable lower; contractual
![Page 41: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/41.jpg)

41
costs having less importance, as work is done on an informal basis; more flexibility in situations
of uncertainty and market changes; and reduction of enforcement costs.
Collaborative R&D also has a tendency to enhance the creation of de facto standards due to
openness, low cost, and easy diffusion. This has two valuable implications for competition.
Firstly, in the case of a standard emerging, the company will have a beneficial position in the
created system and raise the value of their internal competencies. These competencies can be
e.g. technology knowledge or IPR related to the standard. Secondly, the creation of de facto
standards increases the amount of effort put into to the OSS asset and therefore directly impacts
the collaborative R&D. The amount of effort can follow the positive feedback system of de
facto standard creation.
3.2.1.2 Social Capital and Experience Curve
In collaborative R&D both the specific OSS communities as well as the commercial party have
ownership of social capital. The capital owned by both parties contributes to the impact of
collaboration.
Social capital common to the community comprises of its relationship to both OSS developers
and commercial parties. This social network defines the R&D capability of the community. It is
vital to integrate with communities, which have a large social network. An important factor is
that the network includes commercial parties as well as individual developers, because they
typically have large resource pools to invest from.
The company specific social capital with the chosen communities can build differentiation and
grow the efficiency of development. Enabling time and cost reductions through the OSS
community is not a trivial task, because of the informal relationship between parties. Through
this interaction there is a level of social capital built in e.g. the formation of direct relationships,
taking part in community decision making, or even hiring or contracting developers from the
community. As a result of the social capital, the commercial party may be able to exert control
over the community, acquire information otherwise hard to gain, and reinforce the
community from external parties, with all factors differentiating from competition.
The process of collaborative R&D can also lead to a cost structure similar to an experience
curve. The continuous development internally apart from the OSS asset is not a trivial task to
manage in parallel. As the process of collaboration matures, the ability to utilize the
![Page 42: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/42.jpg)
Collaborative R&D Framework

42
collaborative R&D can rise, resulting in an experience curve. This leads to an advantage over
competition utilizing the same communities as collaboration is bound to the internal processes,
people, and their relationships with the community.
Social capital and the experience curve can be considered as important parts of the first-mover
advantage during the transition of an industry. Both factors can result in competition not being
able to match the positive results of collaboration.
3.2.1.3 Created Communities
In specific software areas the firm-level strategy can also be based on creating a new
community. This approach is used when components do not fit into the scope of existing
communities or have a strategic meaning in de facto standard creation around company
contributed software.
A self-created community can impact competitiveness but it may also feature disadvantages due
to uncertainty and complexity. The created community can follow the principles of total access
and open availability to all parties, or it can be a gated community with only the company and
chosen parties having development rights. A self-created community can result in the reduction
of maintenance costs, pre-emption of resources to develop company specific software, a first-
mover advantage, and be used to create and lead a de facto standardization effort. However, the
ability to retain these benefits depends on the ability to gather developers and commercial
parties to invest in the development of the community.
3.2.1.4 Summary of Non-differentiating Software
We can summarize the factors related to non-differentiating software and the impact on
collaboration and competitiveness in the table 5.
![Page 43: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/43.jpg)

3.2.2 Differentiating Software
The firm-level strategy of differentiating software development aims to create value in addition
to the collaborative R&D. The drivers of competition are the creation of specific proprietary
software leading to differentiated products and the ability to leverage the firm advantages. The
two key factors are the software control points and the value of the productization process. It
must be noted that the value chain of proprietary development is not altered by collaborative
R&D.
3.2.2.1 Software Control Points
Because of the impact of commoditization relatively few areas of software products are able to
create differentiating value and leverage firm advantages.
Through particular software control points the company can exert competitive control and create
sustained differentiation. The control points implement distinct technologies such as UI
features, data formats, algorithms, or protocols. These are the software areas where customer
![Page 44: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/44.jpg)

44
value is created and the company exerts total control. Ultimately these are bound to the
sustained advantages because they:
• Contain legal protection;
• Contain technologies that are a part of de facto standards;
• Form virtual networks of products; or
• Create customer switching costs and lock-in.
The creation of software control points should in all cases include IPR, unmatched customer
knowledge, or technological lead. Despite the disadvantages of collaborative R&D, the control
points can both create sustained barriers for a large part of the competition as well as leverage
the competencies, the value of which is increased.
3.2.2.2 Productization Process
In despite of the collaborative R&D, product development carries a large investment. As shown
in chapter 2.3.2, the value chain of software products includes a substantial amount of cost
drivers that are not associated with code implementation or testing. These are not impacted by
collaborative R&D. Collaborative R&D also introduces modified cost drivers in the form of
legal and IPR due diligence. These quantify the existing gap between collaborative R&D and
producing end-user products.
Competitively this gap presents the ability to manage the disadvantages of collaborative R&D
and create value in excess of the OSS asset. Potentially areas such as code implementation,
testing, and design are impacted by collaborative R&D, but this covers approximately 60-80%
of the cost drivers. The management process, legal due diligence, operations such as
requirements and detailed design, quality assurance, integration, and supporting activities are
still complete cost drivers. Therefore the software operations can be a differentiating factor, as
either optimizing these cost drivers or reconfiguring them can result in differentiation.
3.2.2.3 Summary of Differentiating Software
We can conclude how the factors related to differentiating software both manage the
disadvantages of collaborative R&D and create added value in the following table 6.
![Page 45: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/45.jpg)

4. CASE STUDIES
4.1 Design and Case Selection
The goal of the case studies is to research implementations of collaborative R&D, and assess the
framework by seeking empirical validation, feedback, and criticism. Therefore the appropriate
approach is a descriptive case study, to produce and analyze relevant data to illustrate the
chosen cases (Yin, 2003).
The selection of the case is a crucial part of the case study approach. In selection, the concept of
a population is important, because it defines the set of entities from which the research is
conducted on. Also the selection controls the generalization, limitations, and expandability of
the research. (Eisenhardt, 1989)
According to Yin (2003), multiple case studies are more likely to lead to better results and a
higher level of expandability, which is considered true even for a population of two cases. This
also gives the opportunity to directly compare the results of the separate cases. Based on these
rationales the multiple-case approach was chosen.
There are not many companies at this point utilizing OSS in the scope of the study, which
enforces a constraint on the case population. This is why the design only uses two cases. As
both case studies concentrate on analyzing a single company and its product, the design is a
holistic view (Yin, 2003). The phenomenon is researched only regarding the target company
and no sub-units inside the company are used.
4.2 Objectives and Methods
The main objective of the case studies is to examine the impact on competitiveness of
collaborative R&D. This objective can further be split into the following sub-objectives:
• To assess the validity of the proposed framework;
• To analyze how the firm-level strategies impact competitiveness; and
• To provide quantitative measures for the advantage of collaborative R&D.
![Page 48: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/48.jpg)
Case Studies

48
In practice the case studies follow the top-down model proposed by the framework. First, the
overall competitive context and overview of the company are presented, and then the
collaborative strategy is assessed in more detail according to the strategic split. Finally, the case
is analyzed in whole based on the presented data.
The methods used in the study are comprised of open-ended interviews with key people in the
organization or industry specialists, active participant observation, and analyzing quantitative
data acquired through web sources and archival records. The sources for the case studies are
presented in Appendix 1. The interviews were open-ended discussions related to OSS utilization
and dependant on the interviewee’s position. Therefore the used interview protocol was adapted
depending on the interviewee. The overall protocol is specified in Appendix 2.
The tools of Wheeler (2001) and Boehm (1981) were adopted to both analyze the software
structure and estimate the value of the collaborative R&D. The software details of OSS,
proprietary code, and company created OSS were gathered from the companies dedicated
development sites. For the Nokia case, the details are based on the total size of all the
components published, calculating the size of patches contributed by Nokia, or the difference
between original and modified source files, and comparing these to the total size of the product
software stack. The total software stack size was acquired from comparing the OSS SLOC to
the byte size of the complete product software and calculating the difference between these two.
The maintenance structure is based on the amount of unmodified software or components in
synchronization with communities. In the case of Apple, the details were derived from the
published sources and then analyzed according to differences in respect of the original source
code, when and which versions of the components were taken from the communities, or if the
code was unmodified. The maintenance structure was based on the amount of unmodified or
components taken numerous times from open source communities. All of the source code
details include a medium level of uncertainty, due to some components having insufficient data
to analyze their origin and amount of modifications, with precision.
The value of collaborative R&D was estimated based on the total amount of source code and
calculating the COCOMO cost of this software. The basic COCOMO model (Boehm, 1981) is a
tool to estimate the total effort, schedule, and cost of software based only on the SLOC. This
model uses pre-defined parameters to provide a simple estimation. As it does not take into
account the different aspects of the development projects and their complexity, the accuracy is
limited, and could be enhanced with more detailed parameters. The resulting COCOMO cost
was then multiplied with 0.6 to match the impact of OSS on 60% of the value chain of
![Page 49: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/49.jpg)

development and then with the researched percentual share of OSS code of the total software
stack.
It should be noted that for a comprehensive view on the whole phenomenon, a significantly
larger amount of different cases would have to be researched. Also the focus is on the specific
areas of software R&D and collaboration. The total competitive dynamism and strategies are
outside the scope of the case studies.
4.3 Case study 1: Internet Tablet Software Edition 2005
4.3.1 Overview & Approach
The first case analyzes Nokia’s approach to OSS utilization in development of a software
product for handhelds. Nokia is a world leader in the mobile phone and networks infrastructure
industry, but also known for its competence in software technologies. The hardware products of
Nokia utilize both proprietary software and a licensed software platform. For Nokia, the
creation of a novel product and the collaborative R&D strategy has meant two changes. Firstly,
the expansion of existing competencies to a new market, as the product does not include cellular
connectivity and is aimed to match competitive PDA products. Secondly, an opportunity to
configure Nokia’s internal competencies in software development with the external
environment.
Internet Tablet Software Edition 2005 (ITSE2005) was first made public in May 2005. Four
months later the first hardware product that uses ITSE2005, called Nokia 770 Internet Tablet,
was published. The primary software competition for ITSE2005 includes Montavista Linux
products that provide an OSS based distribution for handhelds; Trolltech Qtopia, which is a UI
toolkit for handheld products; Palmsource Palm OS that is a full proprietary handheld operating
system (OS); and Windows CE which is also a proprietary OS. The competition can be divided
to proprietary products (Windows CE and Palm OS), products dual licensed under OSS and
proprietary licenses (Qtopia), and products based on utilizing the OSS asset (Montavista).
There are also some OSS substitutes available, which however are not at a maturity level, where
they could be considered as commercial alternatives.
4.3.2 Software Characteristics & Split
ITSE2005 is a combination of OSS, Nokia developed OSS, proprietary software, and third party
software components. The architecture is not defined into an OSS area and a proprietary area, as
![Page 50: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/50.jpg)
Case Studies

50
components are placed together on all the general software layers. The strategic split is based on
creating the generic kernel and system or application services utilizing OSS, and only
developing proprietary parts in areas such as the UI and state management. The utilized OSS
software includes a variety of mainstream OSS projects. The high-level list of these projects
includes the Linux Kernel 2.6, Debian package management, X-window, GNOME framework
(GTK+, Dbus, Gconf, Gstreamer, and gnome-vfs), BlueZ connectivity stack, and a variety of
OSS application engines. The development has also been based on tools such as GCC,
Scratchbox, and GDB among others.
The total software stack includes 10.5 million lines of code (product and development tools),
which is split into 85% coming directly from OSS, and 15% either modified or developed by
Nokia. In source code lines the respective amounts are 8.9 Million lines of OSS code and 1.6
million lines of Nokia developed software. Out of the 15% created by Nokia, 50% are made
available to the community as modifications to components or totally new components, leaving
roughly 7.5% of the software stack closed.
4.3.3 Non-Differentiating Software
Nokia has decided that the least value can be created from the generic kernel, system utilities,
application services, multimedia framework, and UI toolkit. These components share two
evident factors contributing to this approach: they are considered as the basic building blocks of
handheld software products, and therefore common across competition; and these are the
technologies, where the OSS asset includes mature and actively developed components.
The form of collaboration with the OSS asset happens via two channels: maemo.org, the
dedicated development site for the ITSE2005 as a self-created community; and direct vertical
integration with existing communities.
4.3.3.1 Self Created Community
Community Software Flow
The self-created community has been public since May 2005. The community concentrates on
the development of the integrated OSS and the Nokia created UI toolkit components. The
integrated components are periodically released to the community, with long periods of no
visibility to development. The UI components, on the other hand, are continuously developed in
the open, but in a gated community with only Nokia employees able to commit changes to the
software.
![Page 51: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/51.jpg)
Case Studies
Anttila, Erkko 2006. Open Source Software and Impact on Competitiveness: Case Study.

51
To date, the community has submitted 405 bugs and enhancement ideas and less than 5 relevant
software contributions. The interaction with the community has inputted useful data in fewer
than 10 occasions to support the development. There have also been zero commercial
contributions.
Community R&D Efficiency
At this point in time, it appears that the effort has not lead to efficient collaborative R&D. This
is due to Nokia not being able to attract a critical mass of contributing developers or commercial
parties, and because of the non-transparent development with the community. However,
especially in the case of the specific UI toolkit components, it is too early to judge if the strategy
has the ability to create beneficial collaborative R&D.
4.3.3.2 Existing Communities
Form of Collaboration
The collaboration with existing communities has followed a form of continuous integration
from the start of development. Nokia has invested effort in contributing software to the OSS
asset as well as funding to communities or individual participants of these communities. Some
of the components have been modified to a large extent, but through the continuous software
flow back to the community, the development has stayed in synchronization. This has left Nokia
in a situation where the mass of their software is maintained in the communities, and
collaborative R&D can be utilized to evolve the components. To illustrate the opportunity in
maintenance, the available versions of some components at the start of year 2006 can be seen in
the table 7. In each of these components, the community has produced both improved
functionality as well as fixes for defects.

Community Social Capital
The core communities that Nokia has chosen to integrate with possess large networks of
developers. The GNOME community alone is comprised of over 600 developers with more in
the specific component communities included in the GNOME framework. The Linux Kernel
community has been characterized as including over 1000 contributing developers, and the
Debian community also has close to 1000 dedicated developers.
More importantly, the commercial investment in these communities is substantial. The Linux
Kernel alone gains contributions from companies such as Hewlett-Packard, IBM, Red-Hat, and
Novell. GNOME also receives a stream of investment from the same companies in addition to
Sun Microsystems and Google. The development tools utilized by Nokia, such as GCC, also
harvest a large amount of investments.
It seems that based on the accumulated social capital of these communities with both open
source developers and commercial parties, they are an efficient source of R&D and collect a
substantial amount of investment.
We have continuously worked in collaboration with the OSS projects that we utilize in our
product, which has meant that our software contributions have been integrated into the
mainstream projects. This combined with the work the community has done by their own in the
projects, results in a situation where we can very easily upgrade our software just by taking the
new releases of the projects and integrating them. –Senior project manager-
Open source provides us really a flexibility where we can keep up a continuous stream of
development and upgrading, which cannot really be matched by closed-source production –
Senior Product Manager-
Commercial Transaction Costs
The reduction in commercial transaction costs due to the collaborative R&D is evident. Nokia
has utilized freely available tools that ease the development restraints; has direct interaction
with members of the communities; and most importantly, they have easily found proven
resources to develop the openly available software, which in many cases have been the authors
or main contributors to the components. Examples of this have been companies like Fluendo
with Gstreamer, Openedhand with Matchbox, and Imendio with GNOME.
This impact can be seen in reduced searching costs, flexibility in situations of uncertainty
regarding software implementation or sudden need for resources, and motivated external
![Page 53: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/53.jpg)

53
developers requiring less enforcement costs. Nokia has also employed developers who have
been important parts of the GNOME community, lowering the searching costs for internal
resources, as well.
The advantage of utilizing openly available and modifiable development tools and processes is
a big part of the benefit of our strategy. This removes many bottlenecks which typically hinder
product development. –Operation Director-
When utilizing OSS components, we can just look at the source code and find out who is the
original author of the component. This makes it very easy to find the competent people who
have the best knowledge of these software components. –Software Project Manager-
De Facto Standard Creation
As an emerging phenomenon in 2006, Palm/Access, a direct competitor for ITSE2005,
announced that they will be basing their future products on the same software components and
communities as Nokia. This includes the GNOME framework with GTK+ and Gstreamer as
well as the Linux kernel. Montavista also leverages the same kernel community.
This signifies that the technologies and communities chosen by Nokia are gaining commercial
validity and possibly forming a de facto standard for handheld products. However, it must be
noted that these technologies can still not be considered as an industry standard and the impact
of this phenomenon cannot be assessed in detail within such a short time frame.
Company Specific Social Capital
The social capital between Nokia and the core communities, mainly GNOME and Debian,
seems to exist because of Nokia actively participating and funding the communities, Nokia
developers being active members of the communities, and members of the communities being
either employed by Nokia or contracted for services.
Based on this social capital, Nokia has been able to impact the software decisions of the
community and therefore exert some control on the development to push forward in areas of
importance, e.g. the growing interest of the GNOME community for handheld software. Nokia
has also gained access to technical information otherwise hard and costly to acquire through
informal contacts and relationships.
It also appears possible that Nokia is able to create barriers from competition because of their
first-mover advantage in collaborative R&D and the social capital built between the parties.
![Page 54: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/54.jpg)

These factors can result in a maintenance cost structure in line with the experience curve. This
structure is bound to the resources of Nokia, the community, and the maturing of the process of
development and therefore not directly duplicatable by competitors.
4.3.4 Investment Structure
Based on the COCOMO model we can estimate the value of the utilized OSS to be
$228,000,000, including both product software and tools. We can present the initial and
maintenance investment structure with figure 21. This is based on the software developed in the
collaborative R&D or internally (grey area denotes percentual amount developed internally and
not taken from the OSS asset or made available to the OSS asset).

The important factors from these figures are the following:
• Through the form of collaboration and the high amount of the software available for
collaborative R&D, Nokia is able to utilize collaborative R&D in the areas it deemed as
providing less differentiating value.
• The investment structure is well aligned with the split of Nokia’s software
competencies, the context of the collaborative R&D, and common across competition
areas in handheld software.
Based on these facts, the collaborative R&D seems to be able to deliver efficiency in
development of the chosen software areas, enable the reconfiguration of the value chain, and
concentrate the investment on software that is deemed as competitively valuable.

4.3.5 Differentiating Software
Software Control Points
The differentiating software is spread vertically among the software stack. The specific control
points are the UI, connectivity protocols, power management, and multimedia technologies such
as video and audio features. These control points share four key factors: Nokia holds existing
IPR or competencies in these areas; they are considered different between competitive handheld
products; implementation is investment-heavy; and they can create customer lock-in, virtual
product networks, and implement de facto standards. In contrast, e.g. the core system
technologies are an area where Nokia holds very little IPR. Through these control points it is
possible for Nokia to exert control over the whole product, even though they only implement a
minority (under 5% percent) of the source code lines.
It is obvious that a high rate of OSS lowers the barriers for competitive entry, but because of
our strong advantages in certain software areas, components and products, this is not a
competitive problem. –Software Architect-
Anyone can take all the OSS and make a product out of it, but it’s just not so simple. You need
to have valuable contributions to the market through your own investment, which is always true.
–Operation Director-
Productization
In despite of the collaborative R&D, the development of an end-user handheld software product
contains a variety of cost drivers that are not altered. As handheld software is utilized in
resource constrained hardware products, the importance of optimization, product design,
integration, and testing grows, and all these factors exist as cost drivers for productization.
Collaborative R&D enables Nokia to concentrate their investment on the processes important
for product creation and fitting to their competencies and not those of the OSS community.
Nokia has also decided that the whole integrated product is not made available freely because of
the value it carries, which will enable them to leverage the value in productization. Competitors
are forced to integrate the parts from the existing communities in the similar manner as Nokia
did and continues to do.
![Page 56: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/56.jpg)

56
Utilizing OSS is really not a way to solve all your competitive and operational issues, but it is a
tool to ease some bottlenecks. –Operation Director-
OSS can efficiently move the competitive concentration to other areas of software operations
than they were previously. In the context of your strategy and goals this can really be a huge
advantage. –Senior Product Manager-
4.3.6 Analysis
Framework Validation
The case of Nokia provides validation for the core theories of collaborative R&D impacting
competitiveness through investment on value creation and expanding the scope of
competencies. We can summarize the supporting and contradicting evidence in the following
list:
• The strategic split of software enables Nokia to reconfigure the development value
chain to match the internal competencies and external environment.
• A significant initial and continuous cost reduction is achieved, because of continuous
vertical integration with large communities gaining from OSS and commercial parties
as well as reduced transaction costs.
• Some of the chosen technologies are emerging as de facto standards.
• Nokia is able to create value on top of the collaborative R&D with software control
points and the productization process.
• The created company specific social capital and the maturing process of collaboration
between Nokia and the communities can be seen as a differentiator, based on a first-
mover advantage and as contributing to the efficiency of collaborative R&D.
• The present impact of the self-created community is minimal due to the uncertainty of
attracting developers and commercial parties.

Industry Comparison
The industry is in the transition phase exhibiting heterogeneous collaboration strategies. In this
environment Nokia is able to create relative advantages compared to all parties depending on
their strategies.
• Compared with proprietary development, Nokia is able to concentrate their investment
on value creation, impact the value of competencies, and create a first-mover advantage.
• In comparison to Trolltech’s approach of dual licensed software, Nokia’s advantage
comes in the form of more concentration on value creation, impacting the value of
competencies, and creating a first-mover advantage.
• In the case of Montavista and their approach that is similar to Nokia, the relative
advantage comes in the form of more efficient concentration on value creation because
of more synchronization with existing communities.
As the industry is in the transition phase, Nokia’s strategy has an impact on the value of
software and company competencies, and thus forces the competition to react. Based on the
existing competition utilizing OSS and the move of Palm/Access to leveraging OSS, this seems
to be happening already. However, this movement is not the result of Nokia’s strategy alone.
Because of Nokia’s first-mover advantage it is possible that they will hold an advantage in
future collaboration. However, this cannot be determined yet due to the short time frame.
4.4 Case study 2: Mac OS X
4.4.1 Overview
The second case concentrates on the collaborative R&D of Apple Computer Inc. in their Mac
OS X operating system and Mac OS X Server (Mac OS X). Apple is one of the global leaders in
manufacturing personal computers, software, and peripheral devices. All of the company’s
computer and server products utilize Mac OS X.
Mac OS X was first released in 1999. After this initial release, 5 major upgrade releases have
been made with version 10.0 in 2001 to 10.4 published in 2005. The direct software competition
comes from Microsoft Corporation in the form of Windows and Windows based servers, Sun
Microsystems with their Solaris Enterprise System and servers, and the various OSS offerings
from the GNU/Linux families and the BSD families. The OSS competition includes a variety of
commercial companies, such as Novell with SUSE Linux and Red Hat Inc. with Red Hat, and
community produced products such as Debian. Mac OS X therefore has competition that is
![Page 58: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/58.jpg)

58
proprietary (Windows), commercial but made available for the OSS community (Solaris) to
leverage the maintenance advantage, and originated from the OSS asset by either commercial
or non-commercial parties (SUSE, Red Hat, Debian amongst others).
4.4.2 History and Strategic Approach
The history of Mac OS X leads back to 1996 when Apple bought NeXT Software for roughly
$400 million. The main part of this sale was the ownership of NeXTSTEP the OS, which was
heavily based on OSS—4.3 BSD and the Mach kernel 2.5—, and subsequently formed the base
of Apple’s development leading to Mac OS X. The rationale behind this approach was that
Apple had software competencies in UI design and interaction, but technically the base of their
existing OS had grown old and was never considered reliable. Because the need for a new OS,
Apple would have had to license an external product if they had not opted for buying
NeXTSTEP. This enabled Apple to stay competitive without developing a totally new product,
stay independent of a software supplier, and utilize their existing competencies.
As NeXT had developed their OS by leveraging OSS, Apple inherited this approach. Apple
chose to utilize OSS to configure their internal competencies with the external environment and
to concentrate their investment on value creation.
4.4.3 Software Characteristics & Split
The evolution of Mac OS X has included a range of BSD components as the core of the product.
The main points of this history can be shown in the figure 22.

From the original software in NeXTSTEP, Apple has evolved the product by integrating parts
from NetBSD, OpenBSD, FreeBSD, and adding a new version of the Mach kernel. Ultimately,
as development on the Mach kernel was abandoned by the community, Apple developed their
own kernel called XNU that included pieces of Mach and BSD kernels. During the life cycle of
![Page 59: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/59.jpg)

59
Mac OS X, Apple has also decided to utilize other OSS communities not associated with BSD,
as they have added MYSQL, Apache, Rsync, and Samba amongst others. Apple’s development
has also been based on OSS tools such as GCC, Perl, Python, GDB, and Ruby.
The architecture of Mac OS X comprises of two parts, the Darwin Core and Apple’s proprietary
application services and UI. The strategic split has been implemented by focusing the
development of the core technologies in the collaborative R&D and leaving the higher levels of
the product for internal development. However, as an exception, the engine of Safari browser
has also been developed with the OSS community, even though it is included in the otherwise
proprietary application parts of the product.
The Darwin core and the OSS development tools consist of 17 million lines of source code. This
can be split in 80% developed by the community and 20% created or modified by Apple. In
source code lines, these amounts are 13.6 million lines of OSS and 3.4 million developed by
Apple. The numbers do not include the software details for the proprietary closed layers.
4.4.4 Non-Differentiating Software
Apple identified the Darwin core as the competitively less valuable area where collaborative
R&D could be used. This includes the kernel, device drivers, file systems, networking
functionalities, and other general system utilities. It is evident that this split is based on both the
OSS asset’s concentration of mature and high quality technologies in these areas as well as
these technologies commonly being shared between competitive products and thus not offering
the ability to create competitive value.
The collaboration has been implemented through two channels. Firstly, The Apple developer
site and Opendarwin.org, a community site dedicated to open source development of Darwin,
have been used as a channel to create a community that is directly working on the Darwin core,
and secondly, direct collaboration with existing communities.
4.4.4.1 Self-created Community
Community Software Flow
The self-created community has varied in size, since it’s founding in 2002, with the most
interest gathered during the first two years. At the peek of the community, the amount of active
developers could be estimated at around 150. However, a share of nearly 10% of these
developers was always Apple employees. The source code of Darwin is only made available for
![Page 60: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/60.jpg)

60
developers when a product release is made for customers as well, resulting in long times of no
development visibility for the community.
The contribution flow back to Apple from the community has included roughly 500-700 defect
reports and 300 software commits. Also modifications from Opendarwin have been integrated
to the main software by Apple employees, but this number can be assumed to be relatively low
based on the overall effort on Opendarwin.org. The community activity has almost completely
died in the last year, resulting in close to zero contributions coming back to Apple. The last
release at Opendarwin.org is based on the OS X v. 10.3.2, which is close to two years old. This
is mostly a result of the community not having enough resources to stay up with the internal
development of Apple and the failure in attracting enough mass to contribute to the effort.
The Darwin team has some developers who have originally started as pure OSS hackers, but
have proved their competence in the community and joined the Darwin team afterwards.
–Darwin Developer-
Collaborative R&D Efficiency
It seems that Apple has not been able to benefit from a collaborative effort due to non-
continuous development. The community is not able to keep up with the development and
therefore can not contribute value to Apple. There has also been zero commercial interest into
contributing to Darwin. The community has not been a valuable source of collaborative R&D
and the impact has been in the form of resource hiring and positive PR. This, however, makes
the assumption that the flow through the Apple employees in the Darwin community has not
been substantial enough to change the result of R&D efficiency.
4.4.4.2 Existing Communities
Form of Collaboration
Direct collaboration with existing communities has included varying strategies. Originally
during NeXTSTEP development very little synchronization with the core communities,
especially the BSD communities, was done, which resulted in the software being branched from
the collaborative effort. With kernel technologies Apple developed their own kernel based on
BSD and Mach kernels, which is not in direct synchronization with collaborative R&D, and
therefore is almost exclusively maintained by Apple.
![Page 61: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/61.jpg)
Case Studies

Master’s Thesis, Helsinki University of Technology.
61
Close to the first release of Mac OS X, Apple started to actively contribute work to the
FreeBSD project. Every Mac OS X release since is in synchronization with the matching
FreeBSD releases, as versions 3.2, 4.5, 4.8, and 5.21 have been utilized as the base (table 8).
Table 8: Mac OS X releases and synchronization with FreeBSD
Max OS X release FreeBSD release Date
10.1 3.2x October, 2001
10.2 4.5x October, 2002
10.3 4.8x October, 2003
10.4 5.2x April, 2005
The synchronization effort has, however, been a result of Apple hiring BSD developers to do
internal work, and these employees keeping the internal and external development in
synchronization. It appears that through this informal flow of software, Apple is able to leverage
the FreeBSD development. However, software originating from OpenBSD and NetBSD is still
partially maintained by Apple.
In addition to the core BSD and abandoned kernel communities, Apple has continuously
worked with Apache, Samba, GCC, J-Boss, Rsync, and MySQL communities that provide
important features of Darwin. This work has followed a form of collaboration where the Darwin
development version stays in synchronization by contributions to the collaborative effort or
avoiding forking and therefore easing maintenance. As proof of this work, Darwin has grown by
close to five million lines of source code in the last 3 years with the growth concentrating on
additions from these communities and not the core technologies from BSD.
We continuously recycle projects to the community and again back to our products. Through
this symbiotic development we can implement a development model unlike anything we could
in-house have accomplished. –R&D Senior Manager-
Community Social Capital
The communities Apple chose to collaborate with can be split into two categories based on their
social networks. In the core technologies, the FreeBSD community is actively developed by
roughly 500 developers and the Mach kernel community has been abandoned during the 90’s.
Up to date Apple is the only major commercial party involved in these communities and
therefore Darwin does not gain from commercial investments through these communities. It
![Page 62: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/62.jpg)

62
seems that FreeBSD offers Apple an efficient source of R&D, but suffers from lacking other
commercial contributors.
However, the other communities such as GCC, Apache, Samba, and MySQL have gathered
both active OSS communities and more importantly gain a continuous investment from
commercial parties such as IBM, Hewlett-Packard, Novell, Suse, Nokia, and MySQL. The
amount of OSS developers varies from Apache with close to 100, to Samba and Rsync
estimated at close to 40 developers. It is evident that these communities are a source of effective
collaborative R&D due to community characteristics and commercial investment.
Through the Open source we gain access to contributions of other commercial companies.
-Senior product manager-
Commercial Transaction Costs
Apple has also gained from reducing the transaction costs of development. The Darwin core is
totally built on freely available development tools that ease the bottleneck of working with
commercial parties and can be modified when necessary. Apple has also had direct technical
discussions with BSD communities, but more importantly roughly ten of the core BSD and
Mach kernel developers have been hired by Apple to work on Darwin.
These activities prove Apple’s ability to lower searching costs for competent resources,
enforcement costs, and in uncertain situations lessen the burden of contractual costs in
development or resource hiring.
We have utilized open tools such as GCC which form the foundation of our development work.
–Darwin Developer-
The Darwin team has some developers who have originally started as pure OSS hackers, but
have proved their competence in the community and joined the Darwin team afterwards.
–Darwin Developer-
De Facto Standard Creation
Mach kernel and the BSD technologies have not been able to achieve a status of de facto
standards and therefore this does not impact Apple’s competitiveness. However, some of the
less crucial components, such as Apache, can be considered as a de facto standards, where
Apple mostly benefits from the large collaborative effort the components gain through their de
facto standard status.
![Page 63: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/63.jpg)

Company Specific Social Capital
Considering the social capital built between Apple and the existing communities, the main link
is the hired developers. Through these resources, Apple has access to the source trees of
FreeBSD, information on technical issues, and ability to impact the decision making of
development. As core developers of the community are bound to Apple, the efficiency of
development is enhanced when compared with other companies. It appears that a first-mover
advantage, based on the experience in the process of collaborative R&D and the internal and
external people being apart of this process, more than likely leads to costs of maintenance
exhibiting similar to an experience curve like structure.
With other communities other than the core BSD, there are more influencal parties included,
which is the case with e.g. Apache, diminishing the role of Apple and resulting in minimal
social capital. However, there are existing relationships and processes to work with these
communities, pointing towards an advantage in the efficiency of collaborative R&D.
4.4.5 Investment Structure
Based on the COCOMO model the total cost of internally developing the OSS included in the
Darwin core and the used development tools would be $350,000,000. This gives a rough picture
of the value of the effort in collaborative R&D. The value does not, however, take into account
that this development has spread over a longer period of time and is not split into initial
development and the maintenance part of development. The initial and maintenance investment
structure can be illustrated with figure 23, presenting how the software is spread into closed and
collaborative R&D (grey area denotes percentual amount of software developed internally on
the left or not made available for the collaborative R&D on the right).

The following factors are evident from these figures:
• Because of the form of collaboration and the initially chosen kernel community, Apple
is forced to carry the investment burden for software deemed as non-differentiating.
• In regard to the system utilities Apple is able to move a large part of the maintenance
cost to the collaborative R&D.
• The investment structure is not well aligned with the split of software value, the context
of collaborative R&D, and the value in the external environment.
Concluding on these facts, the investment structure is not the optimum regarding the
opportunity provided by OSS and the external value of software. Even though making openly
available a large part of their software, Apple continuously invests into non-differentiating
software, and fails to fully reconfigure the value chain.
4.4.6 Differentiating Software
Software Control Points
Apple’s software control points are positioned into the UI design and toolkit, and provided
applications. These applications include e.g. social networks and content services owned by
Apple and multimedia features. Most importantly, the control points are based on Apple’s
strong IPR holdings and competence in UI design; applications, which implement virtual
networks and create customer lock-in; and are considered different among competing OS
products. Through these software points Apple holds control over the product, as the underlying
Darwin core is of very little customer value without them.
Apple is differentiated by the ease of use, robust support, and tight integration between its
hardware and software products. It provides a very unique experience that cannot be matched
by imitation or partial duplication, even with access to some of the core technologies we share
with the open source community. – R&D senior manager-
Our open source strategy has made it possible to get more out of the investment into software
engineering. Because of the OSS utilization, we have been able to move more scarce resources
and concentration to the things that are unique for us. –Senior Product Manager-
This enables us to focus on the innovative projects in-house, rather than the commodities.

Productization Process
Despite the collaborative R&D, the productization process carries differentiating value. The
released OSS is far from an end-user product and the designing of an end-user product,
integration of open and proprietary components, testing process, and related cost drivers still
exist. Apple contributes value into the processes that are necessary, but which the OSS
community is not considered competent in, such as requirements management, usability, and
testing. The process of productization, where openly available components are integrated to a
tested product, is very similar to the business model of companies such as Red Hat Inc.
OSS enables Apple to focus its engineering efforts on the "hard" problems and the "boring"
problems, neither of which seems to be easily tackled using the open source model. You can't
have a "one size fits all" approach to software development. Commercial development is good
for certain things, such as user interfaces and debugging. Open source development seems to be
good at building core technologies that serve very specific, well-defined purposes. – R&D
Senior Manager-
Our products are differentiated by what the customers perceive and the level of experience and
usability. – Senior Product Manager-
4.4.7 Analysis
Framework Validation
The case of Mac OS X provides both supporting evidence of collaborative R&D impacting
competitiveness as well as factors leading to less efficient collaboration. These are summarized
in the following list:
• Apple is able to leverage existing competencies through control points and
productization to create value in addition to collaborative R&D.
• The strategic split of software makes possible the reconfiguration of the development
value chain to better match with the external environment.
• There is a substantial cost reduction in initial and continuous development. However,
the reductions are less than optimal because of not staying in synchronization with
certain communities as well as choosing communities that proved to be unsustainable
or unable to gather commercial investment. Reduced transaction costs are also evident.

• Apple creates social capital through hiring BSD developers, which impacts the
efficiency of collaborative R&D and creates a first-mover advantage in collaborative
R&D.
• The self-created community has given very little contribution in the form of
collaborative R&D because of Apple’s failure in keeping the created community at
pace with the internal development and in attracting sufficient developer mass.
Industry Comparison
The industry is in a transition phase, with companies exhibiting various collaboration strategies
ranging from closed-source software to active collaboration. In the context of this competition,
Apple is able to create relative advantages in comparison to the defined competitors:
• With proprietary products, such as Windows, Apple is able to concentrate on value
creation, impact the value of proprietary competencies, and create a first-mover
advantage.
• In case of OSS originated products, e.g. Red Hat, Apple does not gain a clear
advantage from collaborative R&D, but has more control over their product and a
greater ability to create value with control points and productization.
• Compared to Sun’s approach of creating their own community to reduce maintenance
costs, Apple holds an evident advantage with more efficient and wider collaboration
leading to concentration on value creation, impact on competencies, and a first-mover
advantage.
It can be argued that collaborative R&D has a direct impact on the industry-wide competition as
well as on the value of software. There is a gradual industry-wide movement going in the
direction of collaborative R&D, which might over time result in homogenous strategies and
redefined advantages. This movement is, however, not solely the result of Apple’s strategy, but
it is more than likely that Apple’s approach contributes to it.
4.5 Findings and Generalization of Cases
The following section presents the key findings from the two cases, the possibility of
generalizing these findings, and the assessment of the framework. The cases are first directly
![Page 67: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/67.jpg)

67
compared to each other based on the quantitative data, then based on the factors observed. On
this basis conclusions are drawn and discussed.
4.5.1 Quantitative Findings
Both cases include quantitative data, which works as validation and criticism for the impact of
collaborative R&D on competitiveness. The unmodified data is presented in the following table
9.
Table 9: Empirical data from case studies
Empirical Factor Nokia Apple
OSS Originated Code (SLOC) 8.9M 13.6M
Company Created OSS Code (SLOC) 0.8M 3.4M
Duration of Collaborative Development 4-5 years ~10 years
Value of Utilized OSS $228M $350M
Share of Source Code in Collaborative development (Kernel) ~100% ~0%
Share of Source Code in Collaborative development (System) ~88% ~60%
Share of Source Code in Collaborative development (UI Toolkit) ~46% 0%
Developer amount (Existing Communities) ~2500 ~700
Commercial parties (Existing Communities) >10 0-10
Created Community Duration 1 year 4 years
Created Community Size ~10 ~150
Created Community Contribution
(Code contributions) ~5-10 ~300-500
The empirical data plainly presents the similarities and differences of the collaborative
strategies. The conclusions are:
• The cases are similar in the amount of OSS-originated code and the substantial value it
contributes. Both companies are able to leverage large OSS communities, but Apple is
at a disadvantage because they maintain their own kernel technologies.
• There is a substantial difference between the continuous scope and effectiveness of the
collaborative R&D. Nokia utilizes less OSS lines of code; with a higher share available
to existing communities for collaborative R&D; and more OSS developers and
commercial parties contributing to this development.

68
• Apple, on the other hand was able to gather more developers in the self-created
community, but the difference here does not contribute a crucial advantage because
Apple’s community has since been abandoned.
These findings establish the difference in collaborative efficiency and explain Nokia’s ability to
benefit more from their collaborative R&D and have a more evident impact on the industry
environment.
4.5.2 Generalization of Findings
Although just two cases were studied, they both revealed characteristics of collaborative R&D
that impact competitiveness and are shared between the two cases. It is evident that based on the
proposed firm-level strategies companies can reconfigure the value system, create value in
addition to collaborative R&D, concentrate on value creation, expand the scope of existing
competencies more efficiently, and to some extent impact the value of competencies in the
industry. However, both of the case studies environments shared two critical factors that strictly
define the ability to make direct generalizations. Firstly, they both are environments that exhibit
large quantities of existing mature OSS, which is not self-evident in all software environments,
and secondly the software stacks are complex enough to allow value to reside in either higher
layers or specific implementations. These factors strictly limit the generalization of the findings.
We can conclude the main differing and impacting factors of the two cases in table 10.

In leveraging collaborative R&D, the most important factors are the split of software, form of
collaboration, community-owned social capital, and the existence of control points and value
in productization. The form of collaboration and community-owned social capital dictate both
the amount of available collaborative R&D as well as the continuous impact. The split of
software enables the combination of different collaboration strategies. If these three factors are
not implemented successfully, the ability to leverage collaborative R&D is substantially
handicapped. It also naturally follows that company specific social capital; reduced transaction
costs; and emerging de facto standard creation impact competitiveness.
Both cases bring forth evidence that the self-created communities for integrated products are not
an efficient source of collaborative R&D. This is a result of the complexity in creating a large
enough development community around commercially controlled software, creating total
transparency in development, and attracting commercial parties to invest in the software.
However, in Nokia’s case it will only be possible to determine the impact of component
development in the self-created community over a longer period of time.
It can be argued that collaborative R&D can also be considered a source of differentiation.
Both cases exhibited maturing collaboration bound to internal processes and employees, thus
creating differentiation. Dependant on how collaboration strategies converge in the future, the
first-mover advantage can result in a substantial advantage and a beneficial position in the
resulting industry.
It is also evident that the firm-level collaboration strategies can have an impact on the value of
industry competencies. Especially in Nokia’s environment there is a movement towards
collaborative R&D and homogenous collaboration around the chosen technologies, which is a
result of their success in collaboration and devaluing of external competencies. In Apple’s case
there is heterogeneous collaboration across competition with only one party concentrating
purely on closed-source products. Over time it is possible that a large part of the strategies will
mold around the most successful collaboration strategy, but it cannot yet be determined.
4.5.3 Framework Assessment
The proposed framework seems to be robust enough to handle different cases and is to a large
extent validated by the empirical studies. Most importantly it brings forth the critical factors and
the most common shortcomings in relation to the successful implementation of collaborative
R&D during the transition phase of an industry. Successful implementation includes taking the
![Page 70: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/70.jpg)

70
maximum advantage of the OSS asset, managing the disadvantages, and being able to create
value on top of collaboration. All the proposed relative advantages are also, to at least some
extent, proven or discussed.
The cases do, however, present feedback and criticism, which should be applied or taken into
account in the framework. The role of the self-created communities is not empirically proven,
and therefore cannot be considered as important as collaboration with existing communities.
Also the cases and the framework do not take into account the impact of collaborative R&D on
the external complementary innovation or application development. It could be argued that this
can be a part of the created advantage and even result in company specific impact. Also the
impact of the form of collaboration and social capital owned by communities should be
emphasized and directly linked to the resulting continuous R&D efficiency and the other
naturally following factors, such as reduced transaction costs.
There is evident criticism towards the impact of collaboration on industry competencies. In both
cases the movement towards OSS collaboration is a result of a phenomenon larger than these
single companies, which impact competence value. Especially in the case of Apple, it is
impossible to argue what the impact of collaboration has been on the industry-level based on the
presented data. Also, because both cases exhibited heterogeneous collaboration strategies
among competition, there is no clear proof if the first-mover advantage is in fact realizable. This
can only be determined during a longer research time and an industry moving to homogenous
collaboration. These two shortcomings of the studies, lead to insufficient data to prove the
future convergence to homogenous collaboration strategies.
![Page 71: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/71.jpg)

5. DISCUSSION
The research reveals some general observations that are not thoroughly empirically proven, but,
however, warrant further discussion because of their possible impact on the competitiveness of
single companies and the whole software industry.
Through the research disclosing the gradually growing disruptive impact of OSS and the
growing investment in the OSS asset, it is more than likely that this phenomenon will continue
to strengthen. We can make a general hypothesis that more commercial companies will attempt
to leverage the OSS asset and more developers will join the mass of individuals working on
OSS. However, it is still unclear how wide spread the impact of this disruption will be and if it
will only impact specific industries, such as embedded software products.
Considered on the firm-level, during the growth of the disruption, companies choosing to
leverage OSS may have the possibility to dictate the value of their competitor’s competencies
and to build a beneficial position in the future industry. The case studies bring forth that
successful collaborative R&D may actively commoditize software and impact the competencies
of competition, forcing them to react. In this scenario, social capital and the first-mover
advantage could prove to be valuable competitive assets, if the impact is strong enough to force
competition to also adopt collaborative R&D. In any event, it must be taken into account that
such an impact is more likely a result of more than a single company leveraging OSS. The value
of competencies is also defined by a significant amount of factors not thoroughly considered in
the research, making this a complex topic to evaluate and defining it on a level of an
observation, not a subjective research result.
On the industry level, with more companies adopting collaborative R&D and leveraging OSS, it
is possible that this could over time lead to converging homogenous collaboration strategies.
The growing amount of collaborative R&D would create a positive feedback system, where
companies not utilizing the same strategy and communities, would clearly be at an inferior
position regarding their R&D efficiency. The start of this phenomenon is witnessed in handheld
software, through the actions of Nokia and Palm/Access moving to homogenous collaborative
R&D. This phenomenon could in the long-run result in a complete reconfiguration of software
R&D in the specific industries, and in the continuous transformation of product-based
businesses into service-based businesses, as software is transformed into a commodity.

72
Despite the indication from one of the case studies, the homogenous collaboration strategies
across an industry and the transformation of R&D are highly speculative. Based on the
researched effectiveness of collaborative R&D and the growing disruptive force of OSS, there
are rationale to consider this happening, but at this stage there is no proof to validate this
observation. This is because of the limited amount of companies actually conducting
collaborative R&D inside direct competition and to date the non-existent evidence of large scale
homogenous collaboration.

6. CONCLUSIONS
This study has examined how collaborative R&D can impact the competitiveness of product
companies. The objective was to examine the impact on competitiveness of substantial
collaborative R&D and to form a framework, which can be used to understand the impact and
detail the implementation and rationale of the strategy. This objective was addressed by
reviewing relevant literature on competitive advantage, software production, OSS, synthesizing
the findings, and empirical case studies of Nokia and Apple.
6.1 Main Results
The main results of the study are the collaborative R&D framework and the findings from the
case studies.
The framework dictates the different firm-level strategies and the rationale to implement
collaborative R&D, during the transition phase of an industry. Importantly based on the
empirical study, it brings forth the factors and shortcomings to successfully impact
competitiveness and to evaluate the opportunity in collaborative R&D on the firm-level.
The primary result from the case studies is that collaborative R&D can impact competitiveness
with the ability to concentrate the development investment on value creation and more
efficiently expand the scope of existing competencies to new markets.
The case studies indicate that based on the strategic split of software, the companies are able to
reconfigure their development value chain with collaborative R&D. This leads to a better match
of internal competencies and the external environment, and substantial cost reductions in both
initial and continuous development. Quantitative findings indicate that the extent of the impact
is defined by both the firm-level activities, due to complexity in collaboration, as well as the
characteristics of the chosen communities, dictating the effectiveness of collaborative R&D. It is
also proven that substantial collaborative R&D does not destroy the companies’ ability to create
differentiating value and leverage existing advantages, such as IPR or network externalities, in
addition to OSS.
6.2 Assessment of Results
Both of the two case studies provided directly usable results to validate the content of the
proposed framework, in their context. The collected data in both cases is extensive, as it is a
combination of quantitative data from source code analysis and findings from interviews, and it
![Page 74: Open Source Software and Impact on Competitiveness: Case Study · competitive advantages, identifying the distinct competitive characteristics of software products, examining the](https://reader034.vdocuments.net/reader034/viewer/2022050114/5f4af38c1ed97844592edd48/html5/thumbnails/74.jpg)

74
conforms well to the proposed factors in the framework for the firm-level strategies and the
firm-level impact.
Despite of the extensiveness of the data, the findings in the cases are subject to some general
limitations because of the assumptions and simplifications necessary to research this complex
topic. To accurately measure the resulting advantages and overall competitiveness, more in-
depth studies of the competing companies, their internal development and cost structure, and the
overall competitive dynamism, e.g. in the form of market share development, would have been
needed. The empirical factors of OSS value based on the COCOMO model and the exact
amounts of software maintained in the collaborative R&D can be also criticized because of the
uncertainty in the software source details and the COCOMO model. Therefore, the results must
be perceived as qualitative because of the nature of the interpretation from the data.
The number of empirical case studies, their uncertainties, and similar nature, limits the ability to
generalize the main results of the research. The results only provide thoroughly reliable
evidence of the impact of collaborative R&D in the context of the studied industries or nearly
identical competitive environments, in relation to OSS maturity and software complexity. To
warrant extensive generalization to different environments, more in-depth research into the topic
and the applicability of the framework would be needed.
6.3 Exploitation of Results
Taking into account the limitations of the research, the results of the study are directly
exploitable only to the industries, which were included in the empirical study. In these
industries, both the framework and empirical findings can be used as a rationale to evaluate and
implement collaborative R&D, understand the present and possible future impact of OSS, or
mold existing collaboration to be more efficient.
For industries outside of the scope of the empirical studies, the results of the research cannot be
considered reliable and directly exploitable. In cases, where the maturity of OSS is already high
and differentiation can lie higher in the software stack, the results can, however, be used as a
starting point for the evaluation and an indicator of the possible competitive impact of
collaborative R&D now or in the future.

6.4 Recommendations for Future Research
Close to the scope of this study there remain valuable and vital questions. Primarily, the
proposed collaboration framework should be further developed. It would be important to
understand how the proposed factors and collaborative R&D are applicable in taxonomies of
competitive environments, how they can be extended to the overall competitive dynamism of
companies, what is the exact impact on the value of competitor competencies, how they impact
customer value, and applied to a larger quantity of cases. Parallel to this, more in-depth research
into the competitive development of both proprietary and dual licensing should be conducted to
further validate the proposed framework. Further understanding of the details of collaboration
efficiency could also produce valuable results. There are many important details, e.g.
contribution flow, contribution sizes, communication channels, and level of formality that
define the efficiency.
IPR strategies of companies are a continuous question mark when assessing OSS and more in-
depth research into this topic would be justified. To understand these questions, the relationship
of software for hardware companies as a competitive advantage or disadvantage is also an
important topic. It is a clear trend that functionality continuously moves to software, but how it
is driving the competition is still somewhat unclear.
With the case studies concentrating on heterogeneous collaboration strategies, an important
future research area may be the impact and forming of homogenous strategies, the ability for
companies to create advantages in this domain, and the transformation of product businesses to
service-based businesses. Research could also concentrate on an industry-wide dedicated effort
to produce an open software platform and its implications to competition, suppliers, and
customer value.
