Open Source Software Development has become rapidly growing and widely preferable term inthe field of software development. Open Source Software has become much popular among developers, organizations etc. There are various kinds of places on the web in which Open Source Software has hosted such as: Source Forge, GitHub, Google Code, Bitbucket etc. Someof those platform has the power of version control management. From all of those platform, SourceForge was one of the first platform which offer to host projects for free to Open Source projects. According to official report of Source Forge, they claimed to host millions of registered users and host over 500,000 projects and also connects more than 30 million users per month to their directory. All of the Open Source projects and serves which are hosted on SourceForge has more than 4 million downloads per day 1. But now, many users have migrated their projects to GitHub because of extra facilities. Open Source Software Development create a community which has huge interaction and intercommunication among the world’s top developers and also various kinds of users. That’s why Open Source Software has a large number of testers, developers, contributors also.On the other hand, Scrum also plays a vital role as an agile approach in the field of traditional software development. Scrum has greater acceptance in software development industry and it is also rapidly growing and widely used software development framework. Dingsøyr et al claimed that, the most adopted agile approach in the software development industry is Scrum2Mónica Villavicencio.Scrum were originally designed for use in small team 1, members of whose are collocated, face-to-face working. Open Source Software is developed with multiple teams or contributors distributed to several geographical locations. When we try to adopt scrum in the field of Open Source Software Development then we get that there are much more similarities between the process of Open Source Software Development and the Scrum. Some conflicts are also happened with the time boxed concept of Scrum and some other issues.We have focused on this study to identify and compare the similar and dissimilar metrics or terms of Scrum and Open Source Software Development.
