Open collaboration has evolved as a new form of innovation creation in the public sector. Government organizations are using online platforms to collaborative create or contribute to public sector innovations with the help of external and internal problem solvers. Most recently the U.S. federal government has encouraged agencies to collaboratively create and share open source code on the social coding platform GitHub and allow third parties to share their changes to the code. A community of government employees is using the social coding site GitHub to share open source code for software and website development, distribution of data sets and research results, or to seek input to draft policy documents. Quantitative data extracted from GitHub's application programming interface is used to analyze the collaboration ties between contributors to government repositories and their reuse of digital products developed on GitHub by other government entities in the U.S. federal government. In addition, qualitative interviews with government contributors in this social coding environment provide insights into new forms of co-development of open source digital products in the public sector.
