5. Me, myself, my circumstances Bitergia: From research to the real world The software development analytics company Dashboards, reports, consultancy... Uni Rey Juan Carlos: LibreSoft research team Understanding free, open source software development Data analytics approach http://bitergia.com http://gsyc.es/~jgb Jesus Gonzalez-Barahona (Bitergia) Samba, OpenChange & LibreOffice Protocols PlugFest EU 5 / 36

7. All of them... Are free / open source software (and GPL) ...but different business models, languages Are popular ...but different niches, market shares, targets Have a history ...but a very different one Have a community ...but very different in size, composition Jesus Gonzalez-Barahona (Bitergia) Samba, OpenChange & LibreOffice Protocols PlugFest EU 7 / 36
8. The study Jesus Gonzalez-Barahona (Bitergia) Samba, OpenChange & LibreOffice Protocols PlugFest EU 8 / 36
9. What we did, what we didn’t Focus on how they are developed: Processes: how are they performing? Community: who is contributing? We didn’t analyze: Functionality Run-time performance Popularity We produced a dashboard for each of the projects Jesus Gonzalez-Barahona (Bitergia) Samba, OpenChange & LibreOffice Protocols PlugFest EU 9 / 36
