What is a primary goal of InnerSource that differentiates it from open source?

InnerSource applies open source collaboration practices inside an organization while keeping the work internal. Its primary goal is to make company projects more visible to employees and reduce friction when teams contribute across boundaries. Instead of every team working in isolation, InnerSource encourages shared ownership, discoverable repositories, clear contribution guidelines, issues, pull requests, and code reviews. This helps employees reuse existing solutions, avoid duplicated work, and collaborate more efficiently. Unlike open source, InnerSource does not require making repositories public or accepting outside contributors. It also does not remove the need for pull requests; pull requests are often central to the contribution process. The key difference is that InnerSource focuses on internal collaboration using open source-style practices.
