+## DevOps Adoption **(ULTIMATE)**
+
+[Introduced](https://gitlab.com/gitlab-org/gitlab/-/issues/247112) in GitLab 13.7.
+
+The DevOps Adoption tab shows you which segments of your organization are using GitLab's most essential features:
+
+- Issues
+- Merge Requests
+- Approvals
+- Runners
+- Pipelines
+- Deploys
+- Scanning
+
+Segments are arbitrary collections of GitLab groups and projects that you define. You might define a segment to represent a small team, a large department, or a whole organization. You are limited to creating a maximum of 20 segments, and each segment is limited to a maximum of 20 groups. Buttons to manage your segments appear in the DevOps Adoption section of the page.
+
+DevOps Adoption allows you to:
+
+- Verify whether you are getting the return on investment that you expected from GitLab.
+- Identify specific groups that are lagging in their adoption of GitLab so you can help them along in their DevOps journey.
+- Find the groups that have adopted certain features and can provide guidance to other groups on how to use those features.
