Why is This Presentation? ● 2001: Use of OSS in Java very seldom ● 2021: ○ Java itself == Open Source ○ Use of OSS == business as usual ○ Contribution and producing OSS == Business as usual in tech companies
2021: OSS as Success Factor in Tech Companies OSS == Success Factor
2021: OSS as Success Factor in COVID-19 Pandemic OSS == Success Factor
But there is still an exception... 2019: Using OSS forbidden! Source: http://bit.ly/2ZM8oab
And... 2021: contribution and producing OSS still not common in non-tech German companies 2021: All non-tech German companies produce and depend on Software “Software is Eating the World” - Marc Andreessen
Thesis Better Software Product Development needs Open Source Software characteristics Action: Embrace OSS (Use, Contribute and Produce → UCP) to OSS Image source: https://2o7njm2rldjl1npzw315mxb6-wpengine.netdna-ssl.com/wp-content/uploads/2019/01/Better-Way-Sign.jpg
Note: Mediators: Foundations and Platforms ● Foundations ○ In Germany “eingetragener Verein” (e.V.) or “Stiftung” ○ Organization and membership ○ ObjectWeb, Apache, CampusSource, FSF, Eclipse ● Platforms ○ Technical platform ○ Support Macro and Micro software development process* ■ SCM, bug tracking, Wiki / docs, CI / CD pipeline ■ Release, project management ○ SourceForge, Github, GitLab, Bitbucket * Source: http://bit.ly/2NYoP0x
