## Release note Enhancing Workflow Visibility: New Insights into Merge Request Review Time To improve development workflow tracking, GitLab’s Value Stream Analytics has been extended with a new event: last_approved_at. This event marks the end of the review phase and the start of the final pipeline run or merge stage. For example, you can create a VSA stage with last_approved_at as the start event and reviewer_first_assigned as the end event to calculate total merge request review time. Reducing the review time directly impacts the overall cycle time of development, leading to faster software delivery. ### Problem We currently don't have an accurate way to determine the MR review time ion VSA. We have `reviewer first assigned` but no event to signify the end of review and the beginning of the final pipeline run / merge stage. Context from https://gitlab.com/gitlab-org/gitlab/-/issues/499757+ ### Proposal Add a `last_approved_at` event to the MR type which can be used in conjunction with `reviewer first assigned` to calculate the total merge request review time. ### Implementation details: - Update Cycle Analytics under [cycle_analytics/stage_events](https://gitlab.com/gitlab-org/gitlab/-/blob/master/ee/lib/ee/gitlab/analytics/cycle_analytics/stage_events.rb)
