Open source development and delivery occurs over the Internet. Developers are not confined to a geographic area. They work voluntarily on a project of their choice. As new requirements emerge, the software is enhanced by the user/developers. In this paper we show a comparative study of open source and closed source software development approaches and present a software life cycle model for open source software development. %B Proceedings of the 4th ICSE Workshop on Open Source %P 105-109 %> https://flosshub.org/sites/flosshub.org/files/potdar106-110.pdf %0 Conference Paper %B Proceedings of 7th Annual Conference of the Southern Association for Information Systems %D 2003 %T Organizational Structure of Open Source Projects: A Life Cycle Approach %A Donald E.

In lieu of sales figures, the download counts for each project are used to identify the life cycle stage of a random sample of open source projects. A research model is proposed that attempts to measure the fit between the life cycle stage and the specific organizational characteristics of these projects (focus, division of labor, role of the leader, level of commitment, and coordination/control) as an indicator of the success of a project as measured by the satisfaction and involvement of both developers and users. %B Proceedings of 7th Annual Conference of the Southern Association for Information Systems %> https://flosshub.org/sites/flosshub.org/files/wynn2004.pdf
