Azure DevOps is the spiritual successor of the old Team Foundation Services. Its the favorite solution of Microsoft-heavy companies and teams to manage boards, repositories and pipelines. It shines on its wiki feature, which uses a git repository + markdown files for all pages while providing a WYSIWYG editor directly in the browser.
Their approach for other features is confusing to say the least. Components such as pipelines and builds have their own sections independently of the source repository. Its the opposite of similar tools like GitHub Actions or GitLab where the repository has a clear listing of all pipelines and builds in its scope.
Unfortunately the entire kit is poorly glued together, and in practice I’ve seen companies using it in parallel with JIRA, which is a better option for project management anyway.
