Closed Innovation Drawbacks

Adaptations are unsustainable with closed data format

Some innovations do not have a business case for tool vendors

Industrial users end up paying large amounts for improvements which can then be used by competitors who have a normal license cost

18

Mastering? Continuity?

Product strategy change, products may also vanish

Niche tool vendors may get acquired by larger companies, disappear or change their technical focus

19

Control and Secure your Destiny!

Typically less than 20% of Requests For Enhancement (RFE) get into the tool

Proprietary Tool Vendor Ecosystem

100 % of RFE are able to get into the tool e.g. 80% generic, 20% as user extensions

Open Source Software Facilitates

•  Interoperability

•  Creation of de facto standards

•  Migration

•  Extensibility

•  Open Innovation

21

Better Features

Open Innova=on paradigm treats R&D as an open system

Mixing firms external ideas with internal ideas, e.g. IBM 500 US patents for Linux

Designing with experts from different companies equals be#er features

22

Internal Synergies

Protects investment in improvements projects

Synergies between development, services, research, etc.

The whole is greater than the sum of its parts

23

Open Source or Commercial?

PolarSys tools give you both!

Open Source with: •  commercial support •  commercial bug fixes •  commercial contract to

add features

•  etc.

24

Make or Buy?

25

PolarSys tools give you both!:

•  In one project you buy a PolarSys tool from a supplier

•  In the next project you can make your own very specialized feature in the same tool

Aeronautics Long Life Cycle AIRBUS A300 Life Cycle Program began in 1972, produc=on stopped in 2007 2007-‐1972 = 35 years... Support will last un=l 2050

2050-‐1972 = 78 years!

On board soVware development for very long lifecycle products

Embedded System Development Cost Structure

Help build it in open source, even with your direct compe=tors Infra

Value Focus on Value Compete on Products

Selling Features

Operating System Tools

Programming Language

etc.

Large costs can go to build and support infrastructure for which companies derive zero differen=a=ng product value.

27

Better Support

Direct access to developer and large open source community

Same people developing the adapta=ons are developing the main product and handling support.

Fast availability of bug fixes and workarounds

28

Accessibility, Learning Curve

Proprietary tools are some=mes too expensive for some R&D units and specially for service units

Using same tools across R&D and services for the same product speeds up the service area

De-‐facto in industries, universi=es: -‐ people already know how to use -‐ mandate transfer made easier -‐ acquiring companies made easier

Open Source Rules •  Openness Everyone can participate under the same rules

•  Transparency Project discussions, minutes, deliberations, project plans, plans for new features, and other artifacts are open, public, and easily accessible.

•  Meritocracy Becoming a committer or accepting your code depends on peer review and voting by your peers

37

Open Source Definition •  Free Redistribution •  Free Source Code •  Free Derived Works •  Integrity of The Author's Source Code •  No Discrimination Against Persons or Groups •  No Discrimination Against Fields of Endeavor •  Distribution of License •  License Must Not Be Specific to a Product •  License Must Not Restrict Other Software •  License Must Be Technology-Neutral
