Inner Source Defined

Inner Source is defined in (Stol 2011) as follows:

The leveraging of Open Source Software development practices within the confines of a corporate environment. As such, it refers to the process of developing software at an organization that has adopted OSS development practices.

Synonyms for this are the terms ‘‘Corporate Open Source’’ and ‘‘Progressive Open Source’’, as used by other authors. This definition subsumes the meaning of ‘‘Controlled Source’’ in POS; that is, Inner Source may occur within the context of a single organization, or a consortium of organizations.

My research focuses on how companies can benefit from OSS development practices and tools within the confines of their organization. It is important to note that the software product is still proprietary, rather than Open Source. The issue of licensing is therefore not applicable. When companies release their product as Open Source, this is not necessarily “Inner Source.”
