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.}, keywords = {life cycle, lifecycle}, attachments = {https://flosshub.org/sites/flosshub.org/files/potdar106-110.pdf}, author = {Potdar, V. and Chang, E.} }
