### Problem to solve There are 2 implementations of the Value Stream Analytics (VSA) feature: 1. Group-level 1. Project-level In recent months these 2 implementations have begun to diverge substantially, because we have invested in refactoring ([example](https://gitlab.com/gitlab-org/gitlab/merge_requests/16775/diffs#6c1aff793e288e33581de3369f333b8aa888428f_0_38)) and enhancing the group-level implementation, but not the project-level. Basically we have 2 different features now. That is a problem because: - [Different values displayed between the 2 features](https://gitlab.com/gitlab-org/gitlab/-/issues/213029). - Increased cost of maintaining 2 separate features. - Unable to offer cool group-level features (like custom stages) at the project level (per https://gitlab.com/gitlab-org/gitlab/-/issues/30079#note_357374957) ### Further details The ~"group::analytics" [has discussed](https://gitlab.com/gitlab-org/gitlab/-/issues/30079#note_315668874) whether to 1) move FOSS functionality to the group-level and delete the project-level (gitlab#30079) or 2) refactor the project-level to use the new group-level code (this issue). It has been estimated that the [effort would be about the same](https://gitlab.com/gitlab-org/gitlab/-/issues/213029#note_316012604) between these approaches. ### Proposal Refactor project-level VSA to use the group-level code: - [x] [Migrate project-level VSA to use group-level backend](https://gitlab.com/gitlab-org/gitlab/-/issues/213029) gitlab~2492649 - [x] [Eliminate un-used Cycle Analytics code for legacy version](https://gitlab.com/gitlab-org/gitlab/-/issues/292730) gitlab~2492649 - [x] [Add vuex store](https://gitlab.com/gitlab-org/gitlab/-/issues/257828) - [x] [Migrate the project-level navigation to the path navigation layout](https://gitlab.com/gitlab-org/gitlab/-/issues/326695) - [x] [Update project-level stage median requests](https://gitlab.com/gitlab-org/gitlab/-/issues/257830) - [x] [Migrate project level stage table to the new layout](https://gitlab.com/gitlab-org/gitlab/-/issues/326704) - [x] [Migrate project level stage (records) endpoint](https://gitlab.com/gitlab-org/gitlab/-/issues/336864) - [x] [Migrate the project level filters to use the group level filter bar](https://gitlab.com/gitlab-org/gitlab/-/issues/326701)# - [x] [Introduce a default value stream](https://gitlab.com/gitlab-org/gitlab/-/issues/326705) - [x] [Update project level metrics](https://gitlab.com/gitlab-org/gitlab/-/issues/327435) - [x] [Add deep linking for query parameters](https://gitlab.com/gitlab-org/gitlab/-/issues/327457) - [x] [[VSA][FE] Add sorting and pagination to the project level stage table](https://gitlab.com/gitlab-org/gitlab/-/issues/335974) - [x] [VSA Exclude stages a user does not have permissions for](https://gitlab.com/gitlab-org/gitlab/-/issues/335810) ~backend ~frontend Note: This is a tracking issue, not an implementation issue. ### Moved to https://gitlab.com/groups/gitlab-org/-/epics/6749 - [Add customizable VSA features](https://gitlab.com/gitlab-org/gitlab/-/issues/326706) - [Implement the chart data for the default value stream](https://gitlab.com/gitlab-org/gitlab/-/issues - [Add an overview stage to the project level](https://gitlab.com/gitlab-org/gitlab/-/issues/326700) ### Implementation recommendations - See the thread starting here: https://gitlab.com/gitlab-org/gitlab/-/issues/30079#note_356967059
