The most valuable features are related to source code management. Using TFS for source code management and being able to branch and have multiple developers work on the same projects is valuable. We can also branch and merge code back together.
TFS offers valuable integration with Microsoft products for users in a Microsoft environment. It efficiently manages work items, source code, and build releases. With TFVC and Git, TFS supports collaborative development. While stable, merging issues and pricing require attention. Managing test plans is a highlight, despite confusing access controls. Better Microsoft Teams integration is needed, and lack of SharePoint Online support affects document management.
