Sneak preview Open Source Report 2021
− Mars drone Ingenuity  Linux for Rocket Science!
− Good news: many more use open source very
broadly  «heavy users» increased from
29% in 2018 to 49% in 2021
− Number one reason for open source:
Open standards  «Interoperability by design»
− Winner 2021 in programming languages:
TypeScript  2018 only 2%, now 39%!
− Open source IAM did a huge jump
(from 28% to 44%)  Keycloak advanced
massively (253% increase)

Open Source vs. Inner Source

26
Open Source @ Siemens – Insights on Open Source and Inner Source
Benefits of Inner Source
Openness of source code and transparent discussions lead to
− More code reuse  easier to get to know and integrate other code
− Improved software quality  stability, reliability etc.
− Increased intrinsic motivation  pride to show skills to colleagues
Common software repository increases global perspective by developers
− Leverages intra-organizational learning  better understanding
what other units are doing thus enabling knowledge transfer
− Preventing «reinventing the wheel»  getting to know what others
are programming
− Decreases diversity of software components for similar tasks
− Increases organization-wide programming standards
Eckert, Meyer, Stuermer 2017 "How are open source practices possible within a medical diagnostics company? Developing and testing a maturity model of inner source implementation."

  • 26. 26 Open Source @ Siemens – Insights on Open Source and Inner Source Benefits of Inner Source Openness of source code and transparent discussions lead to − More code reuse  easier to get to know and integrate other code − Improved software quality  stability, reliability etc. − Increased intrinsic motivation  pride to show skills to colleagues Common software repository increases global perspective by developers − Leverages intra-organizational learning  better understanding what other units are doing thus enabling knowledge transfer − Preventing «reinventing the wheel»  getting to know what others are programming − Decreases diversity of software components for similar tasks − Increases organization-wide programming standards Eckert, Meyer, Stuermer 2017 "How are open source practices possible within a medical diagnostics company? Developing and testing a maturity model of inner source implementation."
