We explore how the companies allow development contributions from external stakeholders, and what knowledge they let out of their internal software development activities. The results lay ground for further research on how to organize openness of the software development process in hybrid setups where the needs of different stakeholders are partly competing - yet complementary. %B Open Source Systems: Towards Robust Practices 13th International Conference on Open Source Systems %S IFIP Advances in Information and Communication Technology %I Springer %V 496 %P 23-33 %8 05/2017 %U https://link.springer.com/chapter/10.1007/978-3-319-57735-7_3 %R 10.1007/978-3-319-57735-7_3 %0 Conference Paper %B Proceedings of The International Symposium on Open Collaboration %D 2014 %T Volunteer Attraction and Retention in Open Source Communities %A Barcomb, Ann %K Community Management %K FLOSS %K open source %K Recruitment %K Service Duration %K Volunteer Management %K Volunteer Retention %K Volunteers %X The importance of volunteers in open source has led to the position of community manager becoming more common in foundations and projects. Yet the advice for volunteer management and retention is fragmented, incomplete, contradictory, and has not been empirically examined. Our aim is to fill this gap by creating a comprehensive guidebook of best practices drawing from open source practitioner guides and general literature on volunteering, and to subject a subset of practices to empirical study. A method for evaluating volunteer attrition in terms of value to the organization will also be developed. %B Proceedings of The International Symposium on Open Collaboration %S OpenSym '14 %I ACM %C New York, NY, USA %P 40:1–40:2 %@ 978-1-4503-3016-9 %U http://doi.acm.org/10.1145/2641580.2641628 %R 10.1145/2641580.2641628
