Internet technology has emerged as a tool of change in terms of the way technical as well as non-technical communication takes place. In turn, it has made distributed and decentralized development of software projects especially Free/Open Source Software (F/OSS) possible. The F/OSS form of development has become a revolution which has affected the way individual users as well as enterprises think about the development and use of various software projects ranging over a wide area of applications. The F/OSS development approach allows establishment of geographically distributed teams of volunteers who self-learn and self-organize in order to contribute towards developing software projects. As the volunteers may not anticipate receiving direct remuneration for their efforts, it gives rise to questions regarding the factors of motivation leading towards such voluntary contributions for achieving shared goals. This paper reports on a literature survey aimed at exploring and identification of motivation factors driving volunteers of F/OSS projects.
