Companies increasingly adopt InnerSource to gain advantages like:

1. Faster development: Programmers use unit tests, code coverage, and continuous integration to remove bugs at early stages
2. Complete documentation: Code is documented better, both in-code comments and less formally on discussion lists
3. Code reuse: Programmers across the organization understand the code and architecture of modules developed by other teams
4. Cross-team collaboration: Contributions by members outside of the team are frictionless and rarely have to be rewritten
5. Development with GitHub: GitHub maintains private repositories for in-house projects as well as public repositories for open source code
