Abstract

Project-based organizations (PBOs) are becoming increasingly widespread

and important for the modern economy and society. Thus, they attract

significant scholarly attention to their distinctive features. The unit of analysis

employed by the majority of the studies is the project-based organization as a

whole. Hence, the locus of attention stays at the organizational level, whereas

project-related effects are discussed in terms of aggregate properties. With

very few exceptions, projects as distinct entities do not feature prominently

in the discussion of project-based organizations.

This observation creates an interesting paradox. In particular, when projects

are discussed as separate units of analysis, their complex organizational

dynamics, idiosyncrasies, and institutional embeddedness are among

important loci of attention. However, when projects and project collections

are discussed within the context of the PBO, the very same aspects tend to

be downplayed. Most commonly, projects are either neglected or implicitly

assumed to be homogeneous, interchangeable atomic units without internal

structure or dynamics, obediently following orders of the parent organizations.

Their internal organizational properties are overlooked and the individual-

level variables are assumed to have little or no influence on the project

outcomes. This thesis questions these assumptions and posits that

understanding the dynamics at the project operations level might have

important implications for explaining the effectiveness of management

arrangements in the PBO.

In particular, this thesis aims to explore the factors that shape project-based

operations in the setting of the project-based organization. The thesis

examines three particular factors which affect organizing of the project-based

operations: (1) the content of operations; (2) the context of operations; and

(3) the social processes at the operational level. Structurally, the thesis

comprises a cover essay and four appended papers (three of them published

in international peer-reviewed journals).

Largely inductive in nature, the thesis builds on two research studies. The first

study represents an in-depth “insider” case study of project-based operations

in the Operations division of a large pharmaceutical company. It employs a

iv

combination of data collection methods, including semi-structured interviews,

participant observations, and document analysis. The second study represents

a structured framework-based literature review. Recognizing the

organizational properties of projects, the thesis draws upon several literature

streams within organization theory and design to analyze the empirical data.

The results elaborate how the organizing of project-based operations in the

PBO is shaped by the interplay between the content, intra-organizational and

wider institutional contexts, as well as endogenous social processes.

The thesis contributes to the literature on project-based organizations by

developing an institutional, as well as extending a contingency perspective on

organizing project-based operations. Further, the results call for revisiting the

conceptualization of the PBO by questioning the view of projects as atomic

and homogeneous units. Finally, the thesis contributes to the literature by

developing an organization design perspective on the PBO.

In terms of managerial implications, the thesis offers a few frameworks which

can be used to support the decision-making process in a PBO. In particular,

Paper I develops a contingency model of program management competences

(the 3C model), Paper II derives a framework that can help PBO managers in

evaluating the sources of isomorphic pressure on individual projects and

programs, while Paper IV puts forth an organization design model for the

PBO. At a more general level, Paper II discusses how the identified

isomorphic processes within the PBO can limit flexibility, innovation, and

efficiency. Finally, the cover essay discusses the important factors that need

to be scrutinized in order to assess organizing of the project-based operations,

such as the technical content, the project landscape and social landscape or

the influence of institutionalized practices and models.

Keywords: project-based operations; project-based organization; PBO;

contingency; new institutionalism; organization theory; organization design.

Sammanfattning

Projektbaserade organisationer (PBO) ökar i både antal och relevans för både

samhället och den moderna ekonomin, vilket medfört betydande vetenskaplig

uppmärksamhet. Den analysenhet som används för en majoritet av studierna

är den projektbaserade organisationen som helhet. Fokus ligger oftast på

organisationsnivå, medan de projektrelaterade effekterna främst diskuteras

utifrån deras aggregerade egenskaper. Med väldigt få undantag är inte projekt,

sett som separata enheter, framträdande i diskussionen kring projektbaserade

organisationer.

Detta skapar en intressant paradox. När projekt diskuteras som separata

analysenheter, är deras komplexa organisationsdynamik, egenheter och

institutionella förankring viktiga uppmärksamhetsområden. När projekt och

projektportföljer diskuteras inom ramen för PBOs, tenderar emellertid

samma aspekter att vara nedtonade. Oftast är projekten antingen försummade

eller implicit antagna att vara homogena, utbytbara enheter utan inre struktur

eller dynamik, som lydigt följer moderorganisationens order. Projektens

interna organisatoriska egenskaper förbises och de individuella variablerna

antas ha liten eller ingen påverkan på projektresultatet. Denna avhandlingen

ifrågasätter dessa antaganden och postulerar att förståelsen av dynamiken på

projektnivå har viktig påverkan i hur effektiviteten i ledningen av PBOs kan

förklaras.

Mer specifikt så syftar denna avhandling till att utforska de faktorer som

formar verksamheten i projektbaserade organisationer. Avhandlingen

undersöker tre särskilda faktorer som påverkar organisering av

projektbaserade operationer: (1) verksamhetsinnehållet, (2) verksamhetens

sammanhang och (3) de sociala processerna på en operativ nivå. Strukturellt

består avhandlingen av en kappa och fyra bifogade papper (tre av dem

publicerade i internationella peer-review journaler).

Forskningen är av induktiv natur och avhandlingen bygger på två studier. Den

första studien representerar en fördjupad fallstudie av den projektbaserade

verksamheten i ett stort läkemedelsföretag. Den studien har genomförts med

hjälp av en kombination av datainsamlingsmetoder, till exempel semi-

strukturerade intervjuer, deltagande observationer och dokumentanalys. Den

vi

andra studien representerar en strukturerad ramverksbaserad litteraturstudie.

För att erkänna vikten av projektens organisatoriska egenskaper i PBOs

baseras avhandlingen på flera olika litteraturområden inom både

organisationsteori och empirisk dataanalys. Resultaten utvecklar hur

organiseringen av projektbaserade verksamheter i PBOs formas av samspelet

mellan projektens innehåll, intraorganisatoriska och bredare institutionella

sammanhang samt endogena sociala processer.

Avhandlingen bidrar till litteraturen kring projektbaserade organisationer

genom att utveckla en institutionell, såväl som att utöka contingency

perspektivet, när det gäller organiseringen av projektbaserade verksamheter.

Vidare så påkallar resultaten ett behov att återgå till konceptualiseringen av

PBO genom att ifrågasätta uppfattningen att projekt är atomära och

homogena enheter. Slutligen bidrar avhandlingen också till litteraturen genom

att utveckla ett organisationsdesign perspektiv för projektbaserade

organisationer.

Vad gäller det praktiska bidraget så erbjuder avhandlingen några ramverk som

kan användas för att stödja beslutsprocessen i en PBO. Speciellt i papper I så

utvecklas en beredskapsmodell för programledningskompetens (3C-

modellen). I papper II skapas ett ramverk som kan hjälpa PBO-chefer att

utvärdera källorna till isomorft tryck på enskilda projekt och program, medan

Paper IV presenterar en modell för organisationsdesign av projektbaserade

organisationer. På en mer generell nivå diskuterar papper II också hur de

identifierade isomorfa processerna inom en PBO kan begränsa flexibilitet,

innovation och effektivitet. Slutligen diskuterar kappan de viktiga faktorer

som behöver granskas för att bedöma organiseringen av projektbaserade

verksamheter, såsom det tekniska innehållet, projektlandskapet och det

sociala landskapet eller påverkan av institutionaliserade metoder och

modeller..

1. Introduction

1.1. Setting the stage: The project-based organization and its importance as a research area

This thesis addresses the issue of organizing project-based operations in the

context of the project-based organization. The focus is on project-based

organizations as lasting organizational entities that use projects and project

constellations, such as programs and portfolios, as the main principle for

organizing work (see Hobday, 2000; Lindkvist, 2004), rather than one-off

project-based enterprises representing project-specific legal entities that

dissolve after the project completion (see DeFillippi and Arthur, 1998), or

project networks based on alliances between multiple organizations and

individuals (Sydow and Staber, 2002; Windeler and Sydow, 2001).

Management of such project-based organizations is an important research

topic due to the wide dissemination of this organizational form and its

idiosyncratic challenges. First, project-based organizations are becoming

increasingly widespread and important for the modern economy and society

(Cattani et al., 2011; Lundin et al., 2015; Whittington et al., 1999). Project-

based organizations are the dominant form of organizing production across

a number of industries, such as construction (Bresnen et al., 2004; Kadefors,

1995), media and entertainment (DeFillippi and Arthur, 1998; Windeler and

Sydow, 2001), as well as engineering and production of complex products and

systems (Davies and Brady, 2000; Eriksson et al., 2002; Prencipe and Tell,

2001). Additionally, projects and project-based units often play a role of

organizational devices for product development, R&D, and organizational

renewal, and for this reason seem indispensable even within the industries

that have not traditionally relied on projects, such as the automotive

(Cusumano and Nobeoka, 1998; Midler, 2013, 1995), healthcare (Aubry et al.,

2014), telecommunication (Jerbrant, 2013; Lindkvist et al., 1998), logistics

(Söderlund, 2008), packaging (Lindkvist, 2004), pharmaceutical (Freilich,

2015), and computer technologies (Brown and Eisenhardt, 1997; Loufrani-

Fedida and Saglietto, 2016), to name a few.

2

Second, a number of studies emphasized the differences between project-

based and more traditional forms of organizations (Söderlund and Tell, 2011;

Sydow et al., 2004) which complicate the direct transfer of assumptions and

conclusions established for other types of organizations to the project-based

context (Blindenbach-Driessen and Van den Ende, 2010; Bredin, 2008;

Maylor et al., 2015). For example, the success factors and best practices for

development projects differ between project-based and functionally

organized firms (Blindenbach-Driessen and Van den Ende, 2010, 2006). Also,

the structural separation between work carried out in projects and evaluation

procedures performed by line functions creates challenges for matching

compensation to performance (Bredin and Söderlund, 2006). Along the same

lines, the traditional ways of designing reward systems and motivating

employees do not apply in the project-based context, since many project-

oriented engineers are not interested in traditional management and technical

career ladders (Allen and Katz, 1995). To conclude, a number of studies have

indicated that a lack of attention to the idiosyncrasies of project-based settings

can negatively affect such important areas as innovation, operations, and

long-term organizational learning (e.g., Ekstedt et al., 1999; DeFillippi, 2001;

Keegan and Turner, 2002, 2001; Maylor et al., 2015). Consequently, relying

on traditional management and organization theories can hinder designing

well-functioning systems, if one omits to take the aforementioned differences

into account.

Overall, the ongoing burgeoning of the form combined with a number of the

intrinsic challenges makes project-based organizations an interesting and

important phenomenon to study. When addressing these challenges,

researchers should be cautious in relying on existing theories of management

and organization, since the form is associated with a number of important

idiosyncrasies (Söderlund and Tell, 2011).

1.2. Where are projects in the discussion of project-based

organizations?

During the past decade, project-based organizations have attracted significant

scholarly attention (Cattani et al., 2011). Major research themes within the

topic include the distinctions of the project-based organization from more

traditional types of organization (Söderlund and Tell, 2011), the implications

of temporary character of projects for innovation (Gann and Salter, 2000;

Keegan and Turner, 2002), organizational learning and knowledge

management (Grabher, 2004; Keegan and Turner, 2001; Marshall and Brady,

2001; Prencipe and Tell, 2001; Söderlund, 2008), and organizational

capabilities (Brady and Davies, 2004; Davies and Brady, 2016, 2000;

Nightingale et al., 2011), as well as typologies of project-based organizations

(Hobday, 2000; Whitley, 2006).

The unit of analysis employed by many of the studies is the project-based

organization as a whole. The locus of attention stays at the organizational

level, whereas project-related effects are discussed in terms of aggregate

properties, such as decentralization, short-term performance orientation and

distributed work practices (e.g., Bresnen et al., 2004). With very few

exceptions, projects as distinct entities do not feature prominently in the

discussion of project-based organizations. Most commonly, they are either

neglected or implicitly assumed to be homogeneous, interchangeable atomic

units without internal structure or dynamics, obediently following orders of

the parent organization.

This observation creates an interesting paradox in regard to conceptualization

of projects, which is reflected in the duality of assumptions about project

behavior, factors determining project-related dynamics, and appropriate

theoretical lens. In particular, when projects are discussed as separate units of

analysis, among the most salient loci of attention are their organizational

dynamics (Engwall and Westling, 2004; Lundin and Söderholm, 1995;

Packendorff, 1995), idiosyncrasies (Dvir et al., 1998; Lechler and Dvir, 2010;

Shenhar, 2001; Shenhar and Dvir, 1996), and institutional embeddedness

(Ferriani et al., 2009; Ruuska et al., 2011). Projects are shown to be different

4

from each other, as a result of either some intrinsic properties (Shenhar and

Dvir, 1996) or influences of organizational history and context (Engwall,

2003). They are also embedded in multi-layer social structures that affect

learning, management structures and dissemination of practices (Bechky,

2006; Ferriani et al., 2009, 2005; Grabher, 2004; Windeler and Sydow, 2001),

and experience wider institutional pressure (Engwall, 2003; Kadefors, 1995;

Lampel, 2011).

However, when projects and project collections are discussed within the

context of PBO, the very same factors tend to be overlooked or downplayed

by the aforementioned assumptions. The focus shifts to standardized

solutions (Ahola et al., 2014) applied to identical and interchangeable projects

within the PBO. Projects are often depicted as obedient servants of the parent

organization, representing tactical means to execute organizational strategy

(Artto et al., 2008). Their internal dynamics are overlooked and the individual-

level variables are assumed to have little or no influence on the project

outcomes.

Two lines of reasoning could potentially justify the latter approach. Either

these assumptions about projects in the PBO are universally valid, or the

project operations level of analysis is not relevant for the discussion of the

phenomena at the organizational level.

Neither of the options appear to be well justified. There are few empirical

studies that address internal dynamics of multiple projects in the PBO, rather

the literature rests on a set of implicit assumptions. Regarding the

homogeneity assumption, a number of studies documented the existence of

project-based organizations comprising a heterogeneous set of projects, for

example, in terms of scale, importance, technical content etc. (Elonen and

Artto, 2003; Engwall, 2003; Engwall and Jerbrant, 2003; Freilich, 2015;

Geraldi, 2009; Jerbrant, 2009). A typical example might include a Project

Management Office (PMO) carrying out a wide range of organizational

renewal initiatives. Thus, the homogeneity assumption of the literature on

PBOs is not universally valid.

5

On the second point, the literature does contain some examples where the

inclusion of projects as a unit of analysis and/or questioning some of the

assumptions outlined above provided novel insights for the dynamics of the

project-based operations as a whole. Indeed, the contextual differences

between projects executed within the same PBO can explain the effectiveness

of different management approaches (Engwall, 2003). The existence of

different types of complexity in projects (Geraldi et al., 2011; Geraldi and

Adlbrecht, 2007) as well as different types of projects in the portfolio affect

organizational design of the project-based firm since “such heterogeneity

demands structures with different degrees of flexibility” (Geraldi, 2008, p.

349). Heterogeneity of projects can also be instrumental in explaining failures

of introduction of new management practices in the PBO context (Bresnen

et al., 2004). Moreover, the multi-level perspective informs our understanding

of learning within the PBO (Prencipe and Tell, 2001). At a higher level of

abstraction, there is a growing trend of explaining phenomena in the fields of

strategic management and organization theory by utilizing constructs at a

lower level of analysis and/or building upon methodological individualism

(Felin et al., 2015).

Therefore, the importance of understanding project operations dynamics and

its implications in the context of the PBO is supported by theoretical and

methodological arguments. Persistence in neglecting factors that shape

project-based operations might lead to building theories of the project-based

organization upon contestable assumptions and having a number of negative

consequences, such as poor design choices, challenges in introducing new

management practices (Bresnen et al., 2004) or misfits in management

approaches (Engwall, 2003).

To conclude, in spite of some scholars positing that project-based

organization has to be studied as a multi-dimensional and multi-level

phenomenon (Söderlund et al., 2014; Sydow et al., 2004), the operational level

(i.e., the level of projects and groups of projects) is not sufficiently addressed

within the scholarly discussion of project-based organizations. This appears

to be both unjustified and detrimental to understanding of project-based

organization dynamics.

1.3. Research purpose and research questions

The overall purpose of this thesis is to explore how project-based operations

are shaped in the setting of the PBO.

Management scholars have long recognized the importance of content,

context and social processes for understanding organizational dynamics

(Pettigrew, 1987). Along the same lines, a number of studies corroborated the

importance of these aspects within the realm of projects and project-based

management (cf. Blomquist and Packendorff, 1998). In particular, the

intrinsic characteristics of projects (i.e., project content) play an important

role as explanatory variables within the contingency stream of project

management (Hanisch and Wald, 2012; Sauser et al., 2009; Shenhar, 2001;

Shenhar and Dvir, 1996). At the same time, projects are embedded in their

organizational and wider institutional contexts (Engwall, 2003; Grabher,

2004; Morris and Geraldi, 2011). Within the contextual stream of the

literature, a number of studies have shown the influence of such

embeddedness on interior project processes and project outcomes (Bakker,

2010). Along the same vein, context has also been recognized as an important

determinant of practices at the level of project collections, such as programs

and portfolios (Martinsuo, 2013; Pellegrinelli et al., 2007). Finally, project

researchers are increasingly cognizant of the importance of intra-

organizational social interactions and their effects on organizational outcomes

of project-based organizations, such as those of learning and performance

(Bartsch et al., 2013; Di Vincenzo and Mascia, 2012; Prencipe and Tell, 2001).

Building on these threads in the literature, this study investigates three

particular dimensions: the content, context, and social processes. Specifically,

it aims to answer three research questions (RQs) within the setting of the

project-based organization:

RQ1: How are project-based operations shaped by their content?

RQ2: How are project-based operations shaped by their context?

RQ3: How are project-based operations shaped by the social processes?

1.4. Structure of the thesis

Following the Introduction, Chapter 2 presents the theoretical background of

the study. In particular, it commences by discussing the state-of-the art of

research on project-based organizations and the underlying premises of the

literature. It highlights contestable assumptions about projects in the

discussion of project-based operations, and reviews studies which benefited

from a multi-level inquiry. Finally, it briefly discusses factors that could affect

the operational level of the PBO based on extant literature. Chapter 3

discusses the overall research design of the thesis and describes the data

collection and analysis. Chapter 4 summarizes the four appended papers and

provides an overview of the author’s contribution to each of the papers.

Chapter 5 synthesizes the paper results to answer the research questions

outlined in the Introduction. In Chapter 6, the thesis results are put in a

broader context by discussing the theoretical and managerial implications of

the findings. Chapter 7 recapitulates the thesis and restates its theoretical

contribution. Finally, the appended papers comprise an integral part of the

compilation thesis. The structure of the thesis is summarized in Figure 1.

2. Theoretical background

2.1. Project-based organization

The project-based organization has become an indispensable organizational

form in the present-day economy (Lundin et al., 2015; Whittington et al.,

1999). Specific factors that determine the wide dissemination of project-based

organizational logic include its suitability for customized operations (Hobday,

2000), ability to integrate diverse knowledge and skill sets (Hedlund, 1994),

its adaptation, exploration and experimentation capacity (Brown and

Eisenhardt, 1997; Lindkvist, 2008; Siggelkow and Levinthal, 2003), the time-

based nature of competition in many markets, and the existence of strong

performance incentives in smaller, “molecular” organizational units (Zenger

and Hesterly, 1997). Moreover, project-based organizations provide an

opportunity for infusing market elements of governance into hierarchies and

vice versa (Lindkvist, 2004; Zenger and Hesterly, 1997), exploiting advantages

of both traditional modes of governance. Accordingly, introduction of

project-based management as an organizational innovation is driven both by

internal complexity of operations and external competitive and institutional

pressure (Martinsuo et al., 2006).

The project-based form of organizing is not a panacea though, as it entails a

number of distinct challenges. Specifically, the temporal character of projects

poses strong challenges to long-term organizational learning, knowledge

management and innovation (Davies and Hobday, 2005; DeFillippi, 2001;

Keegan and Turner, 2002; Prencipe and Tell, 2001; Sydow et al., 2004).

Additionally, a multi-project environment creates conditions for a fierce

competition over limited organizational resources (Engwall and Jerbrant,

2003), tensions with line functions due to incompatibility of the permanent

and temporary organizational logics and principles (Arvidsson, 2009), and

psychologically stressful work conditions (Palm and Lindahl, 2015; Zika-

Viktorsson et al., 2006). On top of it, the complex political landscape of a

project-based organization can jeopardize implementation of new

management practices and thus hinder organizational renewal (Bresnen et al.,

2004).

10

To complicate the matter further, project-based forms of organization are

examined in the literature under various conceptual terms, such as project-

based organization (Hobday, 2000; Turner and Keegan, 2001; Lundin et al.,

2015), multi-project organization (Canonico and Söderlund, 2010), multi-

project firm (Geraldi, 2009, 2008), projectified matrix organization

(Arvidsson, 2009), project-based firm (Artto and Kujala, 2008; Lindkvist,

2004; Whitley, 2006), multi-project environment (Eskerod, 1996), and

project-oriented company (Gareis, 1991), to name a few.

The differences are not solely linguistic, as project-based organizational

structures exist in a rich variety of forms and configurations (Cattani et al.,

2011; Hobday, 2000; Whitley, 2006). Probably the most common approach is

to draw a distinction between the organizational forms based on the

distribution of decision-making authority among projects and functional units

(Galbraith, 1971; Larson and Gobeli, 1988; Wheelwright and Clark, 1992).

For example, Hobday (2000) distinguishes between project-led and project-

based organizations based on the role played by projects. While in project-

based organizations most internal and external activities are structured as

projects, in project-led organizations they play an important supporting role

in largely non-project-based productive activities. Similarly, the degree to

which projects represent key organizational activities is central to many

classifications. Arvidsson (2009) differentiates between project-based

organizations, relying on projects as sources of revenues, and project-oriented

organizations, where revenues are generated by permanent structures and

processes that are supported by projects. Along the same line, Turner and

Keegan (2001) make a distinction between the project-based organizations

where projects are used to supply bespoke products and services to external

customers (Type 1), and the ones where they play a supporting role to a

mainly routine core business (Type 2). In another typology, Whitley (2006)

proposes four distinct project-based forms of organization, differentiating

between them based on the singularity of goals and outputs and the separation

and stability of work roles. Recently, by conducting a comprehensive review

of these and other sources, Lundin et al. (2015) have introduced project-based

organizations (PBOs) as the ones delivering projects as their business, and

contrasted them with project-supported organizations (PSOs) which

11

increasingly rely on projects in the traditional, internal parts of their

organization.

While acknowledging this diversity, this thesis follows more inclusive

definitions by Lindkvist (2004) and Canonico and Söderlund (2010). Thus,

this thesis defines the project-based organization as one which organizes most

of its activities by projects. It can represent either a firm delivering projects

to external customers or a project-based organizational unit within a larger

firm (e.g., Canonico & Söderlund, 2010; Fricke & Shenhar, 2000).

2.2. Projects in the PBO discourse

Somewhat counterintuitively, projects receive limited attention in the

literature on project-based organizations. On one hand, projects are often

included in conceptual or empirical analysis by the scholars emphasizing the

multi-level nature of the project-based organization (Biesenthal and Wilden,

2014; Loufrani-Fedida and Saglietto, 2016; Müller, 2016; Pemsel et al., 2016;

Prencipe and Tell, 2001). On the other hand, the literature carries a number

of implicit questionable assumptions about the nature of projects populating

a PBO, with important consequences for the range of theories utilized by

researchers to explore the intra-organizational processes and the validity of

the resulting models of the PBO.

Specifically, the PBO literature predominantly views projects as

homogeneous, interchangeable atomic units without internal structure or

dynamics, obediently following orders of the parent organizations. They are

viewed as localized practices or specific processes or devices to deliver tasks,

rather than temporary organizations (cf. Lundin and Söderholm, 1995;

Packendorff, 1995). Consequently, organizational properties of projects are

neglected in the discourse. The lack of attention to the organizational

properties of projects has three important implications for extant theorizing

on the PBO.

First, it contributes to a narrower range of theories utilized to explain intra-

organizational dynamics of the PBO. For example, the emphasis is often on

theories such as agency and Transaction Cost Economics (Müller, 2009) in

12

order to explain organization-project interaction, whereas organization

theories, including contingency and institutional theory, are rarely applied to

explain phenomena at the operational level within the PBO (for some

exceptions, see Bergman et al., 2013; Engwall, 2003).

Second, it leads to an implicit assumption of the homogeneity of projects

within a single PBO. Indeed, if projects are atomic units, they can then be

more readily viewed as similar and interchangeable. This consideration, in

turn, results in the focus on standardized management approaches and

arrangements within the PBO (Ahola et al., 2014).

Third, it is conductive to the view that projects are obedient servants of the

parent organization (Artto et al., 2008). In particular, PBOs are often

conceptualized as rational systems set up for making decisions at the level of

the parent organization and ensuring that they are fulfilled at the level of

project-based operations, with the overarching aim of achieving efficiency

and strategic alignment (Morris & Jamieson, 2005).

There are, however, important exceptions to this view that pay attention to

the organizational properties of projects or reject some of the assumptions

summarized above. Specifically, the assumption of homogeneity of projects

has been challenged in the literature. For example, by distinguishing between

vanguard and subsequent exploitation projects, Brady and Davies (2004)

provided important insights into project capability building when moving into

a new technological or market base. In a similar vein, heterogeneity of projects

can be instrumental in explaining failures of introduction of new management

practices in the PBO context (Bresnen et al., 2004). Accordingly, zooming in

on projects as organizational entities can help in explaining the effectiveness

of different management approaches in terms of organizational context and

history (Engwall, 2003), or in suggesting a novel conceptualization of the

PBO as a loosely-coupled system with important implications for

understanding the organizational dynamics of the PBO (Bergman et al., 2013).

In line with the discussion presented above, this thesis builds on studies that

acknowledge heterogeneity of projects within the PBO and treat them as

13

organizations (Bergman et al., 2013; Lundin and Söderholm, 1995), rather

than a distinct type of operational processes.

2.3. Factors shaping project-based operations

Project-based operations is a term which is commonly used yet rarely defined.

Recently, it has been defined as a type of operations characterized by low-

medium volume and medium-high variety (Maylor et al., 2015, p.106), or

simply described in terms of the steps constituting a typical process from

winning the customer’s order to maintaining support after delivery (Turner

and Keegan, 2000). In this thesis, the concept of project-based operations is

defined more broadly as operational activities that are deliberately structured

in projects and their collections, and managed by applying PM tools. In that

sense, project-based operations do not represent an objective reality inevitably

stemming from the nature of the output and process of operations, but rather

they reflect the framing of the phenomenon by managers and researchers.

For two decades now, the contingency stream within the project management

literature has recognized the importance of addressing project characteristics

and their influence on appropriate management approaches (Engwall, 2003;

Dvir et al., 1998; Howell et al., 2010; Lindkvist et al., 1998; Pich et al., 2002;

Sauser et al., 2009; Shenhar, 2001; Shenhar and Dvir, 1996). In a recent study,

Howell et al. (2010) identified five groups of project contingency factors in

the literature: uncertainty, complexity (as “the degree of differentiation and

interdependence of project elements” (ibid, p. 258)), team empowerment,

criticality, and urgency. Even though the contingency perspective at the multi-

project level is less developed (Howell et al., 2010), some relevant

contributions come from contingency studies of management control in

multi-project organizations (Canonico and Söderlund, 2010), portfolio

management (Martinsuo, 2013), as well as studies highlighting specific aspects

of project governance, such as its relation to knowledge integration

(Lindkvist, 2011).

Furthermore, within the project contingency research, scholars of the

environmental stream, such as Lawrence and Lorsch (1967), Mintzberg

(1979), and Thompson (1967), provide a theoretical foundation for the

14

studies (Hanisch and Wald, 2012). As a result, “the contingency factors

environmental uncertainty and the organization surrounding the temporary

organization attract the most attention” (ibid, p. 12). In the same vein, the

complexity and dynamism of project environment has been identified as an

important factor for adopting appropriate governance approaches and

management tools (Locatelli et al., 2014; Taxén and Lilliesköld, 2008). With

many important exceptions (Lindkvist et al., 1998; Shenhar and Dvir, 2007;

Turner and Cochrane, 1993), intrinsic factors, such as those related to

characteristics of the project task, are less explored as possible contingency

variables. For example, the factors identified by Howell et al. (2010) are in

line with the environmental orientation of project contingency theory and

show some neglect for the technology perspective and the ways in which

actual project work is done. It should be noted though, that the overlooking

of actual work is not a unique feature of the project management research

(Barley and Kunda, 2001).

At the same time, history along with organizational and wider institutional

contexts has strong effects on management of projects within the PBO

(Engwall, 2003; Grabher, 2004). Besides the influence of such embeddedness

on interior project processes and project outcomes (Bakker, 2010), it is also

related to long-term learning and knowledge management at the level of

parent organization (Cacciatori, 2008; Grabher, 2004; Grabher and Ibert,

2011; Prencipe and Tell, 2001). Such embeddedness also results in continuity

of project roles across subsequent projects (Bechky, 2006). Along the same

lines, the organizational context has also been recognized as an important

factor affecting project collections, such as programs and portfolios

(Martinsuo, 2013; Pellegrinelli et al., 2007).

Finally, project researchers are increasingly cognizant of the importance of

intra- and inter-organizational social interactions and their role as

determinants of project outcomes. For example, Ferriani et al. (2009)

identified that the degree of centrality in the social network is positively

associated with the performance of project-entrepreneurs. Moreover, the

social capital reflected in intra-organizational social ties of project team

members has been positively associated with learning (Bartsch et al., 2013), as

15

well as knowledge integration and performance (Di Vincenzo and Mascia,

2012; Prencipe and Tell, 2001).

To summarize, the extant literature, when focusing on projects as separate

units of analysis, indicates the importance of project characteristics, context

embeddedness, and social interactions as the determinants of project

management arrangements. Taking this as a point of departure, the thesis

investigates how these three dimensions affect project-based operations, and

discusses the implications for management of the PBO.

3. Research approach and methodology

This chapter addresses the methodology followed to answer the research

questions and discusses the related research design choices. Upon introducing

the overall research design in the first section, the chapter provides details of

two research studies constituting the backbone of the thesis in two following

sections. In particular, it provides a discussion of the research design, data

collection and analysis, measures taken to support reliability and validity of

the results, and limitations of each of the studies.

3.1. Overall research design

The nature of the compilation PhD thesis has a bearing on methodological

issues. Each appended paper follows its own research method to answer

paper-specific research questions. Table 1 provides a summary of methods

employed in the appended papers, including the details of research

methodology, the theoretical perspective taken, and the correspondence

between the papers’ research questions and the research questions of the

thesis. This section discusses overall research approach of the thesis as a

whole at a more aggregate level, without delving into particular issues of data

collection and analysis pertinent to the separate papers.

It is important to conceive and study the project-based organization as a

multi-level and multi-dimensional phenomenon (Hällgren and Lindahl, 2012;

Pemsel et al., 2016; Söderlund et al., 2014). Following this call, the papers

included in the compilation thesis focused on two different levels of analysis.

While some papers focused on the level of a project or a collection of projects,

others focused on the level of the parent organization as a whole. The

approach spanning several levels within the PBO allowed assessing both the

higher-level intentions behind the arrangements utilized in order to organize

certain activities, and the work content affecting the efficacy of the

arrangements. Moreover, this approach allowed comparing the perspectives

of the actors at different levels in the PBO with regard to the arrangements.

The papers included in the thesis employed different specific units of analysis,

such as management competence areas or isomorphic mechanisms. At the

18

same time, the overall unit of analysis for the thesis is project-based

operations within the project-based organization.

The overall research approach of the thesis had a significant inductive

component and can be viewed as “abductive” (Dubois and Gadde, 2002),

which means that no specific hypotheses were formulated based on extant

literature prior to commencing data collection. Instead, the initial intention

was to gain an in-depth understanding of project-based operations and factors

affecting various intra-organizational governance arrangements (in a broad

sense). The explorative character of research is in line with the identified

theoretical problem of overlooking projects as organizational entities in the

discourse on PBOs. However, the research was not purely inductive. First,

the PhD candidate has brought various preconceptions based on prior

professional experience, as well as ideas from the initial review of the

literature, into the research process (Alvesson and Sköldberg, 2009).

Additionally, the research process involved iterative interactions between

theory and the data (Eisenhardt, 1989; Eisenhardt and Graebner, 2007).

In line with the multi-level and abductive nature of the research, the thesis

builds on two principal research studies: an in-depth ethnography-inspired

case study (Study A), and a structured literature review (Study B). As shown

in Table 1, Study A resulted in Paper I and Paper II, while Paper III and Paper

IV were based on the data collected in Study B.

The case study strategy employed in Study A was particularly suitable for

pursuing an in-depth understanding of complex social phenomena

(Eisenhardt, 1989; Siggelkow, 2007; Yin, 2009). The data was collected using

multiple techniques and analyzed qualitatively. Each paper followed its own

process of data categorization. The data was not used for generalization in the

statistical sense, rather for understanding and theory-building (Eisenhardt and

Graebner, 2007; Flyvbjerg, 2006; Yin, 2009). The two following sections

provide more details about the research studies.

Another feature of the research design is theory triangulation (Denzin, 2006).

The appended papers highlighted different aspects of the empirical

phenomenon borrowing from a range of perspectives within organization

19

theory and design, with an emphasis on contingency and new institutionalism

in organizational analysis. Using various theoretical lenses to explore the

phenomenon strengthened the validity of the findings (Yin, 2009), since

tensions and contradictions between rival explanations provide a more

complete view of a phenomenon (Brady and Maylor, 2010; Poole and Van de

Ven, 1989).

3.2. Study A: “Insider” case study

Research design

Study A had an insider-outsider design (Bartunek and Louis, 1996). The PhD

candidate was acting as an insider, closely following the company managers

in accordance with the ethnographically inspired approach (Fetterman, 2010).

The case study lasted from September 2013 to July 2014. The most intense

data collection period occurred over four months (October 2013 – January

2014), with additional sporadic interactions both before and after the active

phase. During the active phase, the PhD candidate had a desk at the company

office and access to the facilities, permitting him to observe employees in their

work environment and interact freely with them. In turn, the supervisors

contributed with external observations from a distance, acting as outsiders

(Bartunek and Louis, 1996). The insider and the outsiders held a number of

meetings to discuss their observations, ideas and plans for further empirical

work.

The rationale for a single case study in this research is the representative or

typical case (Yin, 2009). In particular, the case organization needed to fulfil

two criteria to be selected: (1) to execute a major part of its activities by

projects (either a project business (Davies and Hobday, 2005) or a project-

based unit of a large company (Canonico & Söderlund, 2010)), (2) to be large

enough to run many projects and allow variation in their characteristics.

Further, the study employed an embedded case study design (Yin, 2009), as it

addressed several units of analysis within the PBO.

A brief overview of the empirical setting

The study was conducted as an in-depth case study at the Operations division

of a major pharmaceutical company. The project work in the division was

managed separately in different organizational units. While the company as a

whole can be best described as a project-supported organization (see Lundin

et al., 2015), these organizational units were clearly project-based. The units

covered by the study included the ones connected to the areas of new product

development, manufacturing, and supply chain. Most of the interviews were

conducted in relation to the latter unit, while the data on new product

development and manufacturing units provided a wider overview of the

organizational setting, allowing for cross-unit comparisons. Within the supply

chain unit, program management approach had been used for a range of

change initiatives within the company. Consequently, the study mainly

concentrated on the program level with some additional insights coming from

other relevant sources such as project or portfolio managers, as well as

program sponsors.

The case covered a range of different projects and programs. The set of

initiatives included supply chain reconfiguration, regulatory compliance, ERP

implementation, establishing alliances with other pharmaceutical companies,

and new market entry (including building new large-scale plants). The broad

geographical coverage of the projects and programs (including Asia, North

America, Europe, and North Africa) represented a distinct feature of the

operations.

Data collection

Throughout the study, the data on a range of management and governance

arrangements was collected, including structures, such as steering committees,

and the way they work; control mechanisms, such as special audit groups;

rules and policies, such as the program prioritization framework, program

management guide, and integrated framework of project and program

assurance; roles, for example, division of the decision-making authority

between project managers, program manager, and the steering group; and

22

practices, for example, project management methodologies applied, and to

what extent they were followed.

In order to acquire a comprehensive view on the subject and to enhance the

study’s validity (Yin, 2009), several data collection methods were utilized,

namely, semi-structured interviews, document analysis, and participant

observations. The data collected during the study is summarized in Table 2.

The study incorporated extensive participant observations of the

organization’s everyday routines, management meetings and informal

communication. The PhD candidate spent 30 full working days of participant

observations at the company’s head office during the four most active months

of the study (in total around 240 hours of participant observations). Every

day spent on site resulted in field notes, with one to four pages of bullet point

quotes and notes on informal interactions with the staff and subsequent

related reflections. The participant observation comprised seven management

meetings lasting between 1.5 and 4 hours, including two ordinary work

meetings for two programs and five division-wide meetings on the

development of program management capability. Additionally, the

introductory meetings with the managers where the scope of research

activities was discussed provided additional data. The findings drawn from

this extensive data were confirmed by the Company’s managers during several

interim presentations and two worldwide webinars conducted by the PhD

Candidate.

Semi-structured interviews also represented an important source of data. The

initial set of programs and respective interviewees was identified together with

the Company representatives, ensuring representation of a wide range of

programs in terms of types of missions and geographical locations. Later on

in the process, the interviewees were asked to provide further contacts to

reduce the initial selection bias. In total, 19 semi-structured interviews were

conducted with program managers, program sponsors, project and portfolio

managers, and other actors. The interviews lasted on average slightly over one

hour, with the exception of the interviews at the executive level, which lasted

between 30 and 40 minutes.

23

The interviews were complemented with the analysis of two broad document

categories: program-specific and general. The first category included internal

audit reports, overview presentations, internal organization and escalation

matrices, lessons learned and program management tools, such as risk logs.

The second category included the internal guidelines and frameworks for the

project, program and portfolio management within the unit and across the

Company.

Data analysis

The data analysis for both papers that emerged from Study A followed the

overall logic of a process which could be metaphorically labeled as an

application of a method theory to a domain theory (Lukka and Vinnari, 2014).

A domain theory here refers to a certain set of knowledge on a specific topic,

while a method theory corresponds to a “meta-level conceptual system,”

which is useful to study the domain theory (ibid, p. 1309). In Paper I the

domain theory represented the literature on program management

competences, while the method theory was the contingency perspective. In

Paper II, the domain theory represented the literature addressing organization

design choices at the project level within the PBO, while the new

institutionalism within organizational analysis played the role of the method

theory.

The collected data was analyzed qualitatively through pattern matching,

allowing the relating of concepts from the domain theory and method theory.

Each paper followed its own process of data categorization, which is

described in the respective papers in more detail. The data was not used for

the generalization in the statistical sense at this stage, rather for understanding

and theory-building (Eisenhardt and Graebner, 2007; Flyvbjerg, 2006).

The validity and reliability of the findings were corroborated by several means,

which are discussed in the appended papers in more detail. First, the data

allowed for triangulation, using various sources and data collection techniques

(Yin, 2009). Second, the conclusions drawn from the data were validated with

the company’s managers during several workshops and worldwide webinars

at the company. Minor corrections were made based on the comments

received during these meetings. However, the papers’ coauthors assumed the

responsibility for the final interpretation.

25

3.3. Limitations of Study A

The main limitation of the study is related to the extent of generalizability of

its findings. In particular, the empirical foundation of the thesis represents an

in-depth insider embedded case study. This might potentially represent a

challenge to the generalizability, as the differences in the organizational

context have been found to have significant effects on the project-based

operations (Martinsuo, 2013; Müller et al., 2008; Pellegrinelli et al., 2007).

Some scholars even hold a view that such contextual differences, for example,

based on the industrial sector, might justify a different set of appropriate

approaches to theorizing about PM phenomena (Artto et al., 2017). While

such concerns should be taken seriously, they do not undermine the

importance of an in-depth qualitative investigation of a social phenomenon,

and the theory-building opportunities that it provides (Barley, 2006;

Eisenhardt, 1989; Yin, 2009).

Thus, the thesis does not claim generalizability of the findings in any statistical

sense. However, it does aim to achieve analytic generalization, that is “to

expand and generalize theories… and not to enumerate frequencies” (Yin,

2009, p. 15). Nonetheless, there are reasons to believe that the conclusions

established in the case might be valid for other PBOs. For example, the

projects and programs investigated within the embedded case study

represented a diverse sample in terms of the technical content and cultural

context (see Paper I), supporting the validity of the findings. Further, the

highly regulated context of the pharmaceutical industry and the culture of

compliance might have amplified the strength of isomorphic processes (see

Paper II). However, there are no reasons to believe that the identified

relationships would be absent in a different PBO. On the contrary, the diverse

set of investigated entities makes us expect even stronger isomorphism in

more homogeneous PBOs, such as within a construction company or a

consulting company. Indeed, existing empirical studies carried out in the

construction industry seem to support this view (Ekstedt et al., 1992;

Kadefors, 1995).

Nevertheless, the thesis propositions need to be validated in further empirical

studies to achieve generalizability. In particular, it would be promising to use

26

a multiple case study or a survey methodology across various industrial

sectors.

Another limitation of the study is related to its relatively short duration, with

the most intensive data collection being carried out within four months. This

time span allowed observation of certain changes in organizing project-based

operations, such as the introduction of new management arrangements.

However, it was not enough to evaluate the long-term effects of the changes.

Additionally, the social structure remained relatively stable over the

observation period. This has limited the ability to investigate the explanatory

power of social processes as a determinant of the project-based operations’

arrangements. Thus, future studies on the topic might benefit from a

longitudinal approach.

3.4. Study B: Structured literature review

Overall approach

Study B was based on a specific structured literature review approach that has

been defined as a framework-based review for understanding (Rowe, 2014),

which is similar to a perspectival literature review (Schryen et al., 2015). The

approach rests on utilizing a conceptual framework to conduct literature

selection and analysis (e.g., Kappos and Rivard, 2008). By adopting a new

perspective as a synthesizing tool, the approach aims to contribute to a

knowledge domain with a novel interpretation of an extant literature (Schryen

et al., 2015). This is achieved “by applying new angles or different macro-

concepts that enable a view which has not previously been explicated”

(Schryen et al., 2015, p. 4). The application of this structured framework-

based approach is becoming popular in various areas of management research

(Besson and Rowe, 2012; Brown and Grant, 2005; Burgess et al., 2006;

Jasperson et al., 2002; Welch and Paavilainen-Mäntymäki, 2014).

The framework-based literature review has a number of distinct features.

First, it emphasizes the role of a conceptual framework and its elements for

identifying knowledge gaps and various preconceptions in the literature

(Besson and Rowe, 2012; Rowe, 2014). Suggesting a novel interpretation of

27

the literature often represents an important outcome of the approach

(Schryen et al., 2015). In particular, applying a conceptual framework enables

synthesizing literature via “abstracting in order to classify and make sense of

sets of research pieces within broad categories, which deal with similar

problems at a certain level” (Rowe, 2014, p. 248). Consequently, instead of

providing a detailed account of individual contributions, the approach puts

an emphasis on the analytical categories and their interrelationship. For that

reason, the framework-based approach is often based on a systematic

literature review (Rowe, 2014).

Second, the approach aims to make a distinct contribution to the literature by

externalizing existing knowledge and by explicitly framing it as a different

theoretical problem (Schryen et al., 2015). Specifically, in case of Study B,

such novelty is related to discussing a theoretical problem of the design of the

project-based organization. Therefore, the study goes beyond reviewing and

recapitulating the literature. In addition to the adoption of a new perspective

itself, framework-based reviews can also contribute to the literature by

identifying research gaps or by a suggesting a research agenda (Schryen et al.,

2015).

Finally, the framework-based review aiming at theoretical understanding

required medium level of systematicity in terms of the inclusion criteria and

quality assessment (Rowe, 2014). Since in this case the focus was on

suggesting a new interpretation, rather than on presenting a detailed account

of separate contributions in the literature, the review entailed a reasonable

rather than a comprehensive coverage, without compromising its

contribution (Rowe, 2014). Moreover, in the case of a multi-faceted research

topic, where the key concepts and research themes are not known upfront, a

keywords-based systematic literature review could have resulted in omitting

important research themes.

The following two sub-sections describe the steps that were taken to identify

and analyze the papers.

28

Literature sample

This section presents a rationale for the methodological choices made in order

to reach the final sample of papers for the analysis. These choices were related

to the choice of journals, the approach to identify individual papers from the

journals, and the time horizon.

In order to select journals for the analysis, the existing literature reviews in

the field of PM were consulted. Three journals, i.e., International Journal of

Project Management, Project Management Journal and International Journal

of Managing Projects in Business, appeared to hold leading positions as

specialized PM journals. According to Ahola et al. (2014, p. 1322), “these

three journals are widely recognized as leading outlets for publishing project-

specific academic research.” Similarly, Turner et al. (2011) suggested

International Journal of Project Management, Project Management Journal

and the IEEE Transactions on Engineering Management as the three major

journals in the field, while the International Journal of Managing Projects in

Business was new when they were writing. The inclusion of the IEEE

Transactions on Engineering Management as an important journal for the

sample is also justified by the fact that it has been an outlet for influential

papers on PM for the past 30 years (Larson and Gobeli, 1989; Lechler and

Dvir, 2010; Müller et al., 2012; Pinto and Mantel, 1990; Shenhar, 1998;

Williams, 2008). Combining the two lists, four peer-reviewed academic

journals in the project management field were selected for the study:

The International Journal of Project Management, (IJPM)

The Project Management Journal, (PMJ)

The project management division of the IEEE Transactions on

Engineering Management, (IEEE TEM)

The International Journal of Managing Projects in Business,

(IJMPiB)

29

While limiting the sample to four journals excluded some important

contributions, it is believed to fit the purpose of the study. First, it allowed

characterizing the specialized project-specific literature, which is useful per se.

Second, it was aligned with the chosen approach of selecting individual papers

as explained below.

The approach of identifying individual papers for the sample was designed

taking into account the multifaceted character of the research on the topic of

the design of the project-based organization. In particular, since a rich variety

of concepts are being used to discuss, for example, organizational

arrangements in the realm of PBOs, employing a literature search based on a

(limited) predefined set of keywords was considered inappropriate.

Consequently, in order to identify an inclusive sample of papers, all issues

published in the journals were examined one by one.

In order to define the time horizon for the study, it was taken into account

that Artto and Kujala (2008) published a comprehensive review of the current

state of project business research in 2008, which focused on the management

of a project-based firm as a key research area. Thus, in order to review the

most recent literature on the topic to allow for comparisons, the time horizon

for the review included eight years between 2008 and 2015 (Study B was

conducted in the end of 2015).

To summarize, Study B reviewed project management literature dating from

2008, in order to identify papers related to the design of the project-based

organization. The journal sample included four leading peer-reviewed

academic journals on PM, for which the coauthors of Papers III & IV selected

all articles that were considered relevant to the topic of the management

and/or design of PBOs. The final sample of papers was formed by merging

the lists of papers collected individually by the researchers. As a result, 177

papers were identified for further review and analysis.

30

Literature review and analysis

Paper analysis comprised four steps. First, simultaneously with the paper

selection process, the coauthors assessed the papers independently. For each

paper, the bibliographic data, major results, key dimensions or mechanisms

studied, which organization design dimensions of the conceptual framework

the paper considered, and the research focus regarding the dimensions were

recorded. The entries were organized as a concept matrix (Webster and

Watson, 2002). In particular, the list of the sampled papers was put in the first

column, while the selected organization design dimensions represented the

headings of the remaining columns. In order to fill out the concept matrix,

the coauthors recorded the specific research themes for each of the

organization design dimensions addressed in the papers. At this stage, the

themes were formulated by the coauthors idiosyncratically, in their own

words.

Second, four working sessions were organized. At these sessions, the

coauthors jointly scrutinized the combined list of papers in order to: (1)

discuss all issues and finalize the sample, (2) discuss the initial categorization

of the papers based on the dimensions they addressed, and (3) develop a

common set of research themes covered in the papers. The process was

iterative in nature and aimed at reducing the effect of individual biases.

Overall, this step resulted in a table of 177 articles classified according to a set

of the identified 35 research themes. Based on the table the coauthors mapped

most common research themes into the organization design framework.

Third, the coauthors carried out a descriptive analysis of the sample. In

particular, they identified the number of appearances of each organization

design dimension and research theme in the paper sample as a proxy for

relative development of the research direction. Then, the coauthors analyzed

the sample based on the number of design dimensions covered by the papers

in order to determine how holistic the papers were. Finally, an in-depth

qualitative analysis of the most holistic papers was performed. Overall, the

analysis achieved the purpose of identifying organization design dimensions

for the PBO.

31

3.5. Limitations of Study B

The most important limitation of Study B is related to the choice of the

academic outlets for the analysis. As it can be seen from the Introduction and

the Theoretical background chapters of this thesis, many relevant

contributions related to the management of the PBO as a whole appeared in

general management, innovation and organization theory journals. Some

examples of reputed journals which occasionally publish papers on the topic

of PBO include Research Policy, Organization Studies, Long Range Planning,

and Scandinavian Journal of Management, among others. It is understood

that an inclusion of contributions from these journals in the sample would

result in a more comprehensive coverage. Nevertheless, it is believed that the

chosen sample allowed for covering most of the relevant contributions, since

project-related publications in general management journals are still relatively

scarce (Bakker, 2010). Also, the choice of specialized PM journals for the

study allowed for characterizing the research done in the community of PM

scholars, rather than organization theory scholars interested in the project-

based form as an empirical setting.

In addition, the study involved certain subjective choices made by the

coauthors. These include choosing the Galbraith’s Star model as the analytical

framework for the analysis and classifying the papers according to the

organization design dimensions they covered. In particular, the classification

process included a subjective evaluation of whether a paper is addressing a

dimension in-depth or just referring to it. While, as discussed in the previous

section, certain steps were taken to reduce such bias, the final set of identified

research themes still represents the outcome of an interpretative process.

Nevertheless, the implications of the study are believed to be robust, since

they were drawn from the analysis of a large sample of the papers, and

changes in the classification of the individual papers are unlikely to affect the

general conclusions.

Paper I

Purpose – The purpose of this paper was to explore how various program

management competences are associated with successful program

management.

Methodology – Overall, the study built on the results of an in-depth case

study (Study A). The study had an insider-outsider design (Bartunek and

Louis, 1996), with one of the authors acting as insider who closely followed

the program managers using an ethnographically inspired approach

(Fetterman, 2010). Several data collection methods and multiple data sources

were used (Yin, 2009), such as participant observations, semi-structured

interviews, and document analysis. The data analysis included several steps.

In the first step, the programs were classified into three categories according

to Pellegrinelli's (1997) typology, based on the type of benefits arising from

the coordinated management of projects. In the second step, the distinct

program management competence areas for each of the program types were

identified. In line with our inductive approach, we chose to derive

competence areas directly from the empirical data and not limit the analysis

by applying a single competence framework from the literature. Finally, after

reviewing the resulting sets of individual competence areas, we

conceptualized them into three distinct core management roles for each of

the program types.

Findings – The findings suggested that various program settings place

distinctively different demands on program managers, thus requiring different

competence profiles to cope with them. Building on Pellegrinelli's (1997)

typology, the study developed a contingency competence model that links

specific competence profiles to the program types. The conceptual

framework represents the 3C model, comprising the Coordinator,

Commander and Convincer management roles, each with its own set of

attributes that are linked to successful management of particular program

types.

35

Research implications – By establishing the link between the program

typologies literature and program management competence literature, the

paper showed that programs should not be treated as a generic and

homogeneous category in discussions on program management competences.

In addition, the findings highlighted program content as a salient contingency

variable for understanding program management dynamics.

Originality/value – The paper provided a rare empirical example of the

contingency approach to program management generally, and to program

management competence in particular. Additionally, it also covered a wide

range of geographical settings and inductively explored microfoundations of

successful management in a research area dominated by quantitative studies.

Contribution to the thesis – The paper contributed to the understanding of

the contingency logic at the level of project-based operations.

36

Paper II

Purpose – The purpose of this paper was to explore how the project-level

organizational arrangements is shaped by institutional forces within project-

based organizations.

Methodology – Overall, the study built on the results of an in-depth case

study (Study A). The study had an insider-outsider design (Bartunek and

Louis, 1996), with the paper author acting as an insider who closely followed

the program managers using an ethnographically inspired approach

(Fetterman, 2010). Several data collection methods and multiple data sources

were used (Yin, 2009), such as participant observations, semi-structured

interviews, and document analysis. The data analysis started with the

development of a theoretical framework, which built on the developed

conceptualization of project organization design as comprising strategy,

structure, processes, and people, on one hand, and on the other hand, on

three isomorphic processes: coercive, mimetic and normative. By analyzing

rich empirical data, the study explicated specific mechanisms that are

responsible for the isomorphic pressure for each of the aspects of temporary

organization design.

Findings – The findings suggested that projects tend to imitate each other’s

structures, strategies and practices with little consideration of the potential

performance effects. Different mechanisms were found to be at play for

different elements of organization design. In turn, the institutions were not

permanent rules of the game. The study also briefly discussed ways in which

project managers shape institutions around them. Thus, it showed how

individual-level attributes of organizational actors and idiosyncrasies of

relational structure affect institutional set-up and isomorphic processes.

37

Research implications – The paper challenged the dominant yet implicit

assumption of goal rationality behind the design of temporary organizations

within project-based organizations. It also provided important implications

for the conceptualization of the project-based organization. Finally, it

extended application of the institutional theory to intra-organizational aspects

by focusing on the organizational fields of multiple temporary organizations

within the project-based organization.

Originality/value – To the best of my knowledge, this was one of the first

attempts to apply institutional logic to project organization arrangements (or

design dimensions) within a parent project-based organization.

Contribution to the thesis – The paper added an institutional explanation

to the factors shaping project-based operations. It also contributed to the

notion of the organizational context by clarifying the roles played by other

projects as well as the parent organization as explanans of project

arrangements.

38

Paper III

Purpose – The purpose of this paper was to evaluate the state-of-the-art of

research on project-based organizations by applying an organization design

lens.

Methodology – The paper followed a structured framework-based literature

review approach (Rowe, 2014). It built upon an analytical framework from

the organization design literature in order to analyze 177 papers that were

published in four leading PM journals between 2008 and 2015, and are

relevant to the design of the project-based organization. The analysis includes

four stages. During the first stage, the authors reviewed the papers

individually while focusing on the organizational design dimensions and

research themes covered by the papers. The second stage comprised four

joint working sessions, where the authors reviewed and reconciled their

individual results in order to iteratively arrive at a common set of research

themes. Then, the themes were used to propose a framework mapping the

research themes into an organization design framework. During the third

stage, the authors conducted a quantitative analysis of the sample to evaluate

the extent of holistic orientation of the papers. Finally, they qualitatively

analyzed the more holistic papers.

Findings – The paper illustrates how the organization design lens can

provide a valuable research perspective on the project-based organization.

The results showed that the literature on project-based organizations

downplays broader organizational issues, such as organizational strategy,

incentive schemes, and performance management systems, while

emphasizing research agenda inherited from research on single-project

management, such as individual management competences, governance

structures, and management processes. In addition, the study highlighted

limited attention in the literature to the interdependence between separate

design choices. This finding contrasts with the importance attached to design

interdependencies within the general management literature. Finally, the study

developed a research framework to map current themes in the literature and

their relative importance, as well as discussed a prospective research agenda.

39

Research implications – Academic implications stemmed from looking at

the project management literature from a fresh theoretical perspective and

putting the project-based organization as a whole in focus. There is great

research potential in studying organization-wide aspects and

interdependencies between various organization design choices in project-

based organizations.

Originality/value – The paper offered a novel way of conceptualizing

research on project-based organizations by linking it to an established stream

within the field of organization theory and design.

Contribution to the thesis – The paper illustrated the capacity of the

organization design lens. It also identified various organization design choices

relevant for project-based organizations, and contributed to the

understanding of multi-level interactions within a PBO.

40

Paper IV

Purpose – The purpose of this conceptual paper was to develop a holistic

model for the design of the project-based organization.

Methodology – As a conceptual paper, this paper combined conceptual

reasoning with the analysis of extant literature. It identified and discussed

concepts and perspectives that are useful for developing a model, in

particular, contingency, configuration and complementarity, holistic models

of organization design and conceptualization of the firm as a web of

temporary organizations. It further reviewed the literature on organization

design to choose a design model as an analytical framework providing the

basis for literature analysis. Then, it discussed distinct characteristics of the

project-based context and argued for a contingency approach to the design

of the project-based organization. Finally, it reviewed what has been written

in the project management literature since 2008 about the management of

project-based organizations, and categorized the topics in the papers

according to a modified version of the Galbraith’s Star Model.

Findings – The paper found that many researchers have written about

individual elements of the Star Model, but very few have written about their

interdependency and the holistic design of project-based organizations. We

also identified contingency factors that affect project-based organization

design, and adapted the Star Model to reflect those.

Research implications – The organization design research stream can

provide a fresh, yet almost unexplored potential to enhance the studies of

organizational aspects of project-based organizations.

Originality/value – To the best of our knowledge, this was one of the first

attempts to treat the design of the project-based organization holistically. It

also provided an overview of how various sub-streams of organization theory

and design could be helpful in developing knowledge about the design of the

project-based organization.

41

Contribution to the thesis – The paper conceptualized the project-based

organization as a web of temporary organizations, and thus countered the

literature on PBOs viewing projects merely as distinct business processes, and

therefore neglecting their organizational properties. It also provided

arguments for a contingency approach as an important foundation for

understanding PBOs, as well as called attention to interdependencies among

various design dimensions and levels in the PBO.

43

5. Synthesis of the results

Consequently, it is structured along the three themes introduced in

Chapter 1, i.e., (1) content, (2) context, and (3) social processes. In order to

facilitate the reading, the correspondence between the research questions and

the appended papers is presented in Table 4. Finally, the findings are

summarized in Figure 2 in the end of the chapter.

Synthesis (cover essay)

The role of content in shaping project-based operations (RQ1)

Project-based operations’ arrangements are influenced by three complementary effects of content of task and activities, intra-organizational and institutional context, and endogenous social dynamics.

The role of context in shaping project-based operations (RQ2)

The role of social processes in shaping project-based operations (RQ3)

44

5.1. Content

RQ1: How are project-based operations shaped by their content?

The findings identify two ways in which the content shaped the project-based

operations: (1) by influencing appropriate management approaches of

individual projects and programs and (2) by affecting organization-wide

arrangements.

First, at the case company, the intrinsic characteristics of activities that needed

to be completed during a project or a program determined appropriate

management arrangements. In particular, Paper I showed that different

program types required distinct sets of management competences to manage

them successfully. For example, programs aiming to exploit a common theme

(e.g., common knowledge, resources, or infrastructure) among relatively

independent projects required effective coordination of distributed activities.

That put stronger demands on the managers to be able to create transparency

of the issues within the program through informal influencing, distilling key

information, structuring information flow across projects, and exercising

flexibility. In comparison, programs pursuing creation of one-off outcomes

outside standard organizational routines (e.g., a new product or a plant)

required managers to be effective in decision making, directing, planning,

controlling, staffing and team building, as well as in providing technical

expertise based on their experience. Finally, programs seeking to improve

existing systems or processes asked for the ability to navigate complex

political context, master scenario planning, act as the program ambassador,

and to influence decisions through a wide personal network. As suggested by

Paper I, a misfit between program type and manager competence profile led

to tensions and challenges, while alignment facilitated successful program

delivery. Consequently, the findings show that the intrinsic program

properties, which are referred to here as program content, affected

appropriate management arrangements.

Similarly, the case study findings show that the projects’ arrangements were

influenced by the content. In particular, in some programs, the program

managers had different requirements for different projects in terms of

45

following the company’s project management guidelines. This flexibility was

exercised unofficially, as all projects were supposed to follow the same

process and prepare the same set of documents and reports. However, for

smaller projects, or when the project manager did not have enough project

management experience (e.g., being recruited from a functional unit), some

program managers made an exception. Hence, the size of the project, as well

as its resource base, influenced the way the operations were managed. In

addition, the differences among projects in terms of level of risk, degree of

interdependency with other projects as well as the level of complexity led to

differences in governance arrangements, both in terms of existence of formal

structures and level of attention from program managers. This was reflected

for instance in differences in frequency of the project steering group meetings

for different projects, and even in the absence of separate steering groups for

some minor projects. Furthermore, while only limited managerial attention

was paid to some projects, other projects required the program manager to

be deeply involved in active risk tracking and resolving issues. Consequently,

the variation in the projects’ contents had significant effects on how they were

managed.

In turn, Papers III & IV discussed the contingency perspective at the level of

projects, project collections, and the parent organization itself, as an

important foundation of project-based organization design. Within

organization theory, technology (which is often understood as the nature of

operational activities) represents a classic contingency variable (Perrow, 1967;

Thompson, 1967; Woodward, 1965). Consequently, Papers III & IV also

indirectly emphasize the importance of the content of project-based

operations.

Overall, these findings are in line with management studies emphasizing

intrinsic properties of an activity as a determinant of its management

structures and approaches (e.g., Birkinshaw et al., 2002; Nickerson et al., 2012;

Sanchez and Mahoney, 1996). Similarly, the project management researchers

have investigated such intrinsic determinants as the project type (Shenhar and

Dvir, 1996), key knowledge integration challenge (Enberg, 2007), complexity

of the problem (Ahern et al., 2014), and uncertainty in goals and methods

(Turner and Cochrane, 1993).

46

Consequently, the results indicate that project or program content represents

an important determinant of project-based operations. In particular, building

on the empirical findings and previous research, the thesis highlights the

characteristics of the task as a determinant of project and program management

arrangements.

Second, besides the influence of the content on the management

arrangements of separate projects and programs, the heterogeneity of the

portfolio, which consisted of various projects and programs, had important

implications for managing the project-based operations. In particular, evident

tensions between the diversity of project/program content and standardized

management structures and procedures had two consequences for the

project-based operations. During the case study, the growing awareness of

the management team about the differences among program types resulted in

the establishment of a new organizational unit responsible for running goal-

oriented programs. This organizational measure aimed at achieving structural

separation of more homogeneous sub-portfolios of projects to help resolve

the tensions between the customized demands of project-based operations

and the standardized organization-wide guidelines. In addition, there were

active discussions on possible further changes to the program management

guidelines in order to acknowledge the diverse nature of the programs.

Furthermore, as the findings showed, in cases when the standardized

guidelines did not fit the nature of the project task, this led to a decoupling of

actual operations from the prescribed formal procedures. Consequently,

differences in the content led to avoidance of the standardized formal

procedures and guidelines.

The findings indicate that uniform solutions and guidelines will, ceteris

paribus, result in lower performance if applied on a non-homogeneous set of

projects and programs (Bresnen et al., 2004). More flexible approaches should

be preferable in case of such heterogeneous portfolios, either in terms of a

higher flexibility of organization-wide guidelines and frameworks, or in terms

of a higher degree of discretion for managers that allows improvising

(Jerbrant and Gustavsson, 2013).

47

To summarize, the findings showed how, when considering projects or

programs in isolation, the efficiency pressure determines the way in which

project-based operations need to be organized in order to achieve the fit

between the content of projects and programs and their management

arrangements.

5.2. Context

RQ2: How are project-based operations shaped by their context?

The influence of the context on project-based operations is discussed in two

layers: the intra-organizational context and the wider institutional context.

Intra-organizational context

The current findings suggest that project-based operations are strongly

affected by the organizational arrangements at the level of the PBO. As Paper

II showed, coercive mechanisms in the case had significant effects on the

project-based operations. In particular, the superior entities affected project-

based operations in two ways: (1) by prescribing formal management

structures and approaches for project, program, and portfolio management,

such as the program capability guide or project portfolio prioritization

framework, and (2) by creating informal expectations about the expected

outcomes and the process by which they should be reached (Paper II). As

shown in Paper II, these prescriptions, in combination with a multi-level

assurance system, put pressure on projects and programs to follow the

procedures. Along the same lines, Papers III & IV emphasized the

importance of fit between organizational design choices made at the level of

the parent organization and at the level of projects. That means, for example,

that a need to contribute to a declared organizational strategy puts a limit on

the range of the decisions a project manager is considering while devising the

project strategy. Taken together, these findings showed how various aspects

of management of project-based operations were shaped by the top-down

pressure from superior organizational structures.

48

At the same time, in the case study, the relationship between operational and

organizational levels was reciprocal. Specifically, some project and program

managers were successful in getting their approaches enacted as formalized

best practices (Paper II). These formalized structures, in turn, affected the

subsequent project-based operations. Moreover, some program managers

were very skillful in navigating the political context in order to influence

decisions made at the organizational level as, for instance, by orchestrating

the steering group composition for their programs (Paper I). Consequently,

besides the identification of direct top-down influences on the project-based

operations, the findings indicate how these effects were mediated by the

actions of some managers.

In addition to these hierarchical influences, horizontal linkages also played an

important role in shaping the project-based operations. In particular, non-

project based functional units affected the operations directly, for example,

due to the HR department’s involvement in hiring, assessment, and

promotion decisions and via participation in the steering groups (Papers I &

II). Besides, the functional units also affected the operations indirectly by

putting requirements on the technical content of the work (Paper II). As an

example, the marketing department’s decision on packaging solutions for

various markets had implications on how the work was structured within the

product development projects (Papers I & II). Consequently, the project-

based operations were shaped by the functional units through the supply of

key resources (such as personnel) while retaining a partial control over them,

by direct participation in key decisions, as well as by controlling the technical

content.

Wider institutional context

The approaches and arrangements utilized within the studied project-based

operations were also influenced by the wider institutional context at the

societal and industry levels. As discussed in Paper II, the studied project-based

operations were shaped by a number of institutional forces. For example, the

management toolbox of the project and program managers was mainly

formed by popular models, frameworks, and approaches, such as the

Ishikawa diagram and the A3 problem-solving approach (Paper II). Thus,

availability and legitimacy of popular management models affected the

operations. In addition, accepted societal norms and priorities also affected

the way programs were managed. Particularly, the issues of sustainability were

included in many of the program documents and discussed during the

meetings (Paper II). Besides, the tradition of heavy regulations in the

pharmaceutical industry led to heavy documentation and prescriptions being

viewed as a norm, thus affecting the amount of paperwork a program team

had to fulfil (Paper II). On top of it, project and program managers

represented a relatively homogeneous group in terms of educational

background, professional experience, and personality traits (Paper II). Finally,

even though the managers were rarely members of the professional PM

associations, they widely consulted material such as the Project Management

Institute’s Project Management Body of Knowledge while developing their

own guidelines and frameworks (Paper II). Consequently, the wider

institutional context had significant effects on processes, structures and

strategies of the projects and programs.

To summarize, the findings identified two layers of context for the project-

based operations and illustrated their effects on the management

arrangements. The first layer represents the intra-organizational context and

comprises both superior entities which overlook the project-based operations

and non-project based units within the company. The second layer represents

the wider institutional environment of the company. It shapes project-based

operations by the availability of popular management models, influence of

professional associations and consulting companies, existence of shared

industry-specific norms and practices, and influence of common societal

values and norms on decision-making. Taken together, the two contextual

layers had a strong impact on how project-based operations were carried out.

50

5.3. Social processes

RQ3: How are project-based operations shaped by the social processes?

The final element which emerged from the study is related to social processes

at the level of project-based operations. This element is endogenous to

project-based operations and takes into account the internal social structure

at the levels of projects and individuals.

“Project landscape”

The findings indicated the existence of imitation among various projects and

programs (Paper II). Despite the differences in goals, scale, and technical

content of operations (Papers I & II), it was common to copy structures,

frameworks, approaches and even configuration of the steering groups.

Findings of Paper II discussed the existence of an informal hierarchy among

projects which affected the legitimacy and appeal of their project management

practices. As a result, some projects and programs functioned as role models

for others.

Two factors appear to be of significant importance in determining the status

of a project or program. First, the perception of success was one of the key

factors shaping the process. Individuals engaged in projects and programs

tended to imitate approaches utilized by initiatives which were perceived to

be success stories. For example, program managers of successful programs

were approached both directly and through competence networks to provide

advice on how a program could be structured, or to share a certain framework

or tool. Another factor conducive to being the role model was related to the

scale and complexity of projects and programs. Large initiatives gained higher

visibility and credibility within the organization, and their approaches and

structures were imitated more often. These processes were facilitated by the

mandatory lessons learned sessions, and dissemination of brief reports after

program completion. Overall, these considerations highlight the role of

legitimacy and availability in the dissemination of management models. To

that end, project-based operations are influenced by the configuration (or

landscape) of projects and programs (Paper II). These findings relate to the

51

importance of prestige, legitimacy, and uniqueness of projects as explanans

of their internal dynamics (cf. Engwall, 2003). However, the distinct feature

of the current study is that it associates the perceived characteristics of

projects with their role as objects of imitation by other projects (Paper II).

“Social landscape”

At the level of individuals, the social landscape played an important role in

the mimetic processes. Similar to the project status discussed above, the

empirical findings indicate the existence of an informal hierarchy of managers

related to their perceived successfulness and expertise (Paper II). As the

findings indicate, management structures, frameworks, tools and approaches

were disseminated through formal and informal competence networks from

the “champion” managers to all others. Additionally, individual-level

proximity, including connections arising from, for instance, friendship, co-

location, experience of working together and commonality of interests in

organizational politics, played important roles in this process. In particular,

such proximity enabled more frequent communication and a deeper level of

trust between the managers belonging to the same group. As a result,

management approaches were commonly copied from the leaders of these

groups. Consequently, the findings suggest three factors as important

determinants of the position in the informal hierarchy of managers:

experience, perceived successfulness, and centrality in certain groups of

managers.

The informal hierarchy in the case organization was dynamic, as several

program managers exerted efforts to promote themselves as the most

experienced and legitimate role models (Paper II). This was achieved by

establishing connections with superiors, active participation in the intra-

organizational competence networks, and disseminating their own

approaches as best practices. Overall, the informal social configuration

mediated the effects of context and content, and thus shaped the project-

based operations. These findings are in agreement with and elaborate on prior

studies highlighting the importance of intra-organizational social ties for

explaining dissemination of project practices (cf. Bartsch et al., 2013; Di

Vincenzo and Mascia, 2012; Prencipe and Tell, 2001).

52

To summarize, the findings identified endogenous social processes as an

important determinant of project-based operations. In particular, individuals

engaged in various projects in the PBO tended to imitate each other’s

management structures and approaches. This imitation was conditioned by

three main social processes: (1) sharing of tools and approaches by managers

via formal and informal competence networks within the company, (2)

interpretation of organization-level arrangements and guidelines within

groups of managers, and (3) promotion and institutionalization of best

practices as formal guidelines by the most ambitious managers. These

processes were profoundly affected by the informal hierarchies of projects

and individuals, determining the direction of dissemination of project and

program management arrangements.

5.4. The interplay of the factors

Based on the findings of the appended papers, the role of content, context

and social processes in shaping project-based operations could be

summarized as depicted in Figure 2. Firstly, the figure acknowledges the

diversity of content of projects and programs (shown with different shapes

for symbols depicting the temporary organizations), and illustrates its

implications for managing the project-based operations. As the findings

suggest, the characteristics of the task that a project or program is set to

accomplish affect the way the operations need to be managed in order to

achieve success (shown with green color). In addition, awareness about the

diversity of content can lead to structural adjustments, such as creation of a

new organizational unit to run a sub-portfolio of particular types of projects

or programs (see Figure 2). Secondly, the figure shows the reciprocal

influences between the operations and their context. In particular, the figure

depicts how the wider institutional context affects the operations, by

providing a management toolbox and creating a normative pressure on

project participants (shown in the upper part of Figure 2). Moreover, the

intra-organizational context affects the operations in two ways. Superior

organizational entities impose various frameworks and guidelines on the

temporary organizations, as well as form informal expectations about how

they ought to be managed. In addition, non-project based organizational units

53

affect the operations by exercising control over various technical aspects of

the projects and by providing project participants and steering group

members who retain their connections to the units. In turn, the operations

influence the intra-organizational context in three ways: by the emergence and

institutionalization of best practices, by affecting organizational politics, and

by leading structural adjustments. Finally, the figure highlights the role of

endogenous social processes in shaping project-based operations. In

particular, it depicts the imitation processes as borrowing of structures and

approaches among projects and individuals (shown with small black arrows

in Figure 2). The project landscape and social landscape play an important role in

these processes by determining which projects and individuals become role

models for others. As shown in the figure, the position in the informal

hierarchy is related to the level of successfulness, visibility, and centrality to

certain groups or coalitions.

There is a complex interplay between the identified factors and the way

project-based operations are managed. For example, the present findings

indicate that the various functional departments of the organization – related

to the context dimension – indirectly influence the project-based operations

by exercising control over the technical content and providing project

participants. Similarly, the institutionalization of organizational best practices

– as an outcome of the endogenous social processes – defines parts of the

intra-organizational context for subsequent operations. Consequently, the

identified factors are not independent and should be seen as complementary

in explanation of the phenomenon.

Despite being a static representation of the PBO, the diagram implies a

dynamic nature of these processes. In particular, it depicts reciprocal

influences between the temporary and permanent organizational structures

which unfold in time. For example, the institutionalized best practices emerge

from their application in some projects and programs, depend on the past

social landscape (connection to the past), and are imposed on the subsequent

projects as formal guidelines (connection to the future). Similarly, the

structural adjustments arise from the tensions between uniform guidelines

and customized demands of projects (connection to the past), thus resulting

in a new intra-organizational context for future projects in the PBO

54

(connection to the future). Finally, the social structure itself is dynamic as

individuals get promoted, transferred into other units, get assigned to

more/less successful projects, leave the company, establish new connections,

and so forth. Thus, the findings support the importance of the organizational

history and path dependency in explaining project-based phenomena

(Engwall, 2003; Leonard-Barton, 1992).

6. Implications

The previous chapter synthesized the findings of the appended papers in

answering the research questions. Derived primarily from a single, embedded

case study, these findings have some obvious limitations (discussed in

Chapter 3). Consequently, further research is needed to rectify the identified

concepts and relationships and to validate the findings in other contexts

before they can be claimed to have general validity in a statistical sense.

However, assuming that the findings are generally valid, the present chapter

discusses some of the findings’ most significant implications for theory and

practice.

6.1. Implications for theory

First, the present findings challenge the view of the project-based

organization (PBO) as a rational, vertically aligned system of project

deliveries. While much of the previous literature emphasizes top-down

mechanisms and intentionality behind the arrangements of the project-based

organizations (Hobday, 2000; Loufrani-Fedida and Saglietto, 2016), the

findings suggest that lateral processes and wider institutional norms have a

strong effect on the dynamics of the PBO. This means that while the findings

confirm the importance of the institutional context for projects (cf. Lindkvist,

2004; Morris and Geraldi, 2011), they go beyond that by questioning the

extent to which it could be proactively managed. Consequently, future

research should recognize and further investigate the role of these

institutional processes as determinants of the PBO’s management structures

and approaches along with their implications for organizational performance.

Second, while past research has introduced the view of the PBO as a loosely-

coupled system (Bergman et al., 2013) by building on the notion of project as

a temporary organization (Lundin and Söderholm, 1995), the present findings

indicate the significance of lateral couplings among projects and individuals.

Thus, while studies building on the notion of project as a temporary

organization typically emphasize project boundaries (Scarbrough et al., 2004)

and decoupling (Bergman et al., 2013), the current findings show that

58

management models permeate these boundaries through mechanisms of

imitation and informal sharing of information, experiences, as well as

management techniques, via formal and informal competence networks.

Consequently, there is a need to revisit the view of the PBO as a loosely-

coupled system of autonomous temporary organizations. Instead, future

research needs to investigate the antecedents, emergence and consequences

of the lateral couplings within the PBO.

Third, the findings raise questions about the validity of some traditionally

claimed advantages of the PBO as an organizational form. While extant

literature praises the PBO form for its flexibility, innovation, and efficiency

(cf. Brown and Eisenhardt, 1997), the identified isomorphic processes can

hinder these characteristics. In addition, the identified mechanisms can offer

alternative explanations for several empirical phenomena reported in the

literature. For example, the “improvement paradox” (Brady and Maylor,

2010), that is, the situation in which obvious improvements are not

implemented in a project setting, has been explained in terms of a complicity

of actors involved in the project (ibid). However, the isomorphic mechanisms

identified in this thesis suggest instead that this phenomenon can be due to

intra-organizational institutional pressures from the parent organization and

other projects. The same reasoning applies to the “renewal paradox” (Ekstedt

et al., 1992), that is, the fact that project-based companies are often not

innovative despite having excellent conditions for introducing innovative

solutions when new projects are started from scratch. Similarly, while past

research has noted that PBOs that operate many uncertain projects

simultaneously are likely to end up in a less profitable zone of the

“bureaucratization of chaos” (Geraldi, 2008), and has suggested the dictate of

inflexible structures as the explanation of the phenomenon (ibid), the present

findings suggest that these constraints appear as a combined effect of

different isomorphic mechanisms rather than due to coercive forces alone.

Consequently, this means that future research will need to include the intra-

organizational institutional forces as a rival explanation of empirical

phenomena.

Furthermore, while past research has pointed out that the literature often

treats projects in PBOs as homogeneous units which are subject to top-down

59

standardized governance mechanisms (Ahola et al., 2014), the present

findings suggest that heterogeneity of project-based operations and the

characteristics of the social structure have important implications for the

management of the PBO. In particular, these aspects are crucial for

understanding the (lack of) effectiveness of homogeneous solutions (Bresnen

et al., 2004) despite common attempts to standardize operations in PBOs

(Ahola et al., 2014; Bergman et al., 2013). Consequently, the findings also call

for a more nuanced understanding of the complex interplay between the

heterogeneous operations and the structures and approaches which are used

to manage them in the project-based organization.

In addition, the thesis calls attention to refining the concept of project context

within the PBO by specifying the role played by other projects and PBO

structures in relation to the focal project. While it has long been

acknowledged that projects in PBOs affect each other by being a part of the

organizational context (Engwall, 2003; Engwall and Jerbrant, 2003; Prencipe

and Tell, 2001), the present findings provide a more detailed understanding

of the inter-project processes by identifying the effects separate projects have

on each other. These findings seem promising and call for further research

inquiring into the characteristics of project landscapes, identifying their

configurations and patterns of inter-project dynamics, as well as

understanding their implications for the management of PBOs.

Finally, while past research mainly focuses on organizational-level variables

to discuss PBOs (Söderlund and Tell, 2011), this thesis highlights the

importance of individual-level variables as explanans of the PBO dynamics.

In particular, the present findings suggest that informal social hierarchy is

important for understanding intra-organizational dissemination of

management structures and approaches. In addition, the findings illustrate the

role of project actors as “institutional entrepreneurs” (Battilana et al., 2009),

who exert their expert power to influence the institutions of the PBO. Thus,

building on similar research trends in other streams of management, such as

the “humanization of strategic management” (Pettigrew, 2012), and the

microfoundations movement within organization theory (Felin, 2005; Felin

et al., 2015), the thesis highlights the importance of a deeper understanding

of the role of social landscape in shaping PBO’s management arrangements.

60

Consequently, more research needs to be done to understand the role of

individuals and their actions in structuring projects within the PBO (cf.

Hällgren and Lindahl, 2012, 2017), as well as their interactions with the

arrangements at the PBO level.

6.2. Implications for practice

In terms of managerial implications, this thesis offers two kinds of

contributions. First, the papers included in the thesis put forth a few

frameworks and models that can be utilized to support managerial decisions

in a PBO. In particular, Paper I develops a contingency model of program

management competences (the 3C model) that can be useful for a range of

HRM decisions, such as the appointment and promotion of program

managers. In particular, managers can determine the type of program at hand

and appoint a manager whose competences match the competence areas

identified by the model. In addition, they can analyze the portfolio of

programs in their organization and, depending on the prevalence of a

particular program type, develop tailored training, development workshops

and hiring and promotion criteria which will target the competence areas

necessary for the program type. Consequently, the 3C model provides a

refined HRM tool useful for managing a diverse set of programs.

Similarly, Paper II results in a framework that can help PBO managers

evaluate the sources of isomorphic pressure on individual projects and

programs by providing a list of ten isomorphic mechanisms within PBOs.

This list can be used as a checklist in management discussions, where

managers will subsequently reflect on the strength of each of the mechanisms

in their organization and analyze its consequences. In addition, by connecting

the mechanisms to specific organization design choices, the framework can

assist managers in organizational redesign efforts. In particular, when a certain

change is deemed necessary, the managers can use the framework to assess

which specific isomorphic mechanisms can hinder the change and respond

accordingly. For example, if the aim is to change project strategy, the

managers need to make sure that coercive forces, such as formal frameworks

and guidelines, as well as the expectations of steering group members, are

aligned with the desired outcome.

61

In turn, Paper III and Paper IV put forth models and frameworks related to

the organization design of the PBO. These models can be used as both

checklists and the starting point of discussion in order to identify the

organization design choices at hand. In addition, they can also be used to

discuss whether there is a fit between various organization design dimensions

in the PBO and, in the case of a misfit between certain dimensions, which

changes need to take place to achieve a proper fit.

Second, the results also suggest more general implications for the

management and organization of PBOs by drawing attention to the aspects

and ideas that might otherwise be overlooked. In particular, Paper I supports

the view that “one-size-fits-all” solutions for projects and programs is

detrimental. Consequently, practitioners should carefully examine the content

of their project-based operations when selecting management arrangements.

In addition, Paper II discusses how the identified isomorphic processes might

limit such important PBO properties as flexibility, innovation, and efficiency.

Practitioners can benefit from this idea in several ways. For example, they

need to be vigilant about the fact that even though particular projects might

require certain management approaches and arrangements due to their

intrinsic character, their managers can copy practices from each other. As

discussed above, in cases when the copied approaches will not fit the nature

of the follower projects, this can result in lower efficiency. Additionally, for

the projects that require a significant degree of innovation either in content

or structures, it can be beneficial to use structural and spatial separation to

insulate the projects from the intra-organizational institutional forces, as in

the case of the “skunkworks projects” (Rich and Janos, 1994) or “tiger

projects” (Clark & Wheelwright, 1992).

Furthermore, Paper III and Paper IV call attention to the fit between the

project-level and PBO-level arrangements as well as between various

organization design dimensions. Hence, PBO managers need to scrutinize the

fit in organizational design choices across organizational levels, for instance,

by investigating whether the project strategies are aligned with the

organizational strategy.

62

Finally, the cover essay discusses the important factors that need to be

scrutinized in order to assess organizing of the project-based operations, such

as the technical content, the project landscape and social landscape, or the

influence of institutionalized practices and models. One of the important

implications of these findings is that PBO managers need to analyze the project

and social landscapes when they want to introduce new management approaches

and structures. The findings suggest that the most legitimate projects are the

ones which are characterized by high scale/visibility and are perceived to be

successful. Similarly, there are informal leaders among project and program

managers who often serve as role models for others. The findings indicate

that their high status is often manifested in perceived expertise,

successfulness, and centrality in certain groups of managers. Consequently,

PBO managers need to identify these “star” projects and “champion” project

and program managers, and start introducing new management practices

beginning with them, in order to ensure legitimacy and broad acceptance of

the new approaches.

63

7. Conclusion

This thesis aimed to explore how project-based operations are shaped in the

setting of the project-based organization. It started by highlighting a number

of common yet questionable assumptions about projects in the literature on

PBOs, and discussed the implications of these assumptions. Building on two

research studies, that is, an insider case study of project-based operations in

the Operations division of a large pharmaceutical company, and a structured

framework-based literature review, the thesis investigated three particular

dimensions which affect project-based operations: (1) the content of

operations; (2) the context of operations; and (3) the social processes at the

operational level. The present results elaborated on how the organizing of

project-based operations in the PBO is shaped by the complex interplay

between these three dimensions, and put forth novel concepts, such as intra-

organizational isomorphic processes and project and social landscapes, which are helpful

for understanding the PBO dynamics. Upon answering the research

questions, the thesis discussed a number of specific implications of the

findings for theory and practice.

7.1. Contribution

The contribution of this thesis lies in exploring the factors that shape project-

based operations in the PBO context. Overall, the thesis can generally be

viewed as an example of what Geraldi and Söderlund (2016) called a Type 2

of project studies, i.e. the type which recognizes projects as temporary

organizations, acknowledges the diversity of projects, builds on general

management and organization theories and aims to offer some implications

for practice. Nevertheless, it also contributes to the identified important

research directions of Type 3 research, which subscribes to an even more

reflexive view on projects, namely by addressing the interplay between the

technical core and social processes in project-based operations, as well as by

going “beyond projects” in the investigation of a particular setting of the

PBO.

64

More specifically, the thesis makes the following inter-related theoretical

contributions. First, it extends the contingency perspective on management

of project-based operations by investigating the relationship between

program content and program management competences.

Second, it develops the institutional perspective on organizing project-based

operations by identifying and explicating pertinent isomorphic processes and

by contributing to the understanding of the intra-organizational institutional

set-up. It discusses the powerful mechanism of imitation, and identifies

factors that play an important role in this process, such as the personal

proximity, reputation, and perception of prior results.

Third, it refines the concept of project context within the PBO by specifying

the role played by other projects and PBO structures in relation to the focal

project. The results contribute to a better understanding of the inter-project

processes by singling out the effects of separate projects.

Fourth, it broadens the conceptualization of the PBO by analyzing the effects

of individual- and project-level influences on the arrangement at the PBO

level. The results show how project and program managers exert their expert

power to institutionalize their management approaches as best practices,

acting as institutional entrepreneurs.

Fifth, it revisits the view of projects as atomic homogeneous units within the

PBO by recognizing their organizational properties. Drawing upon the rich

literature of organization theory and design, the thesis makes a contribution

to the literature by applying an organizational lens to projects in order to

explain the internal dynamics of the PBO.

Finally, it develops an organization design perspective on the PBO. The

contribution is achieved by integrating several streams within organization

theory and design literature to propose an organization design model of the

PBO, by identifying specific organization design dimensions and factors

affecting the dimensions in the PBO context, by emphasizing a multi-level

character of the PBO, as well as by proposing a future research agenda.
