(In the context of {T94165}, WMF is changing its quarterly review process, and this is a goal task created basically after the fact in order to accommodate to the new process.)
The following text is extracted from the last quarterly review, and eventually fine tuned:
Expected impact: Fluent development process across teams and with volunteers
Success measures:
* Overall participation keeps growing (active users, projects).
* WMF Engineering processes use Phabricator for cross-team coordination.
* WMF teams still using Trello have identified actionable blockers.
* The Wikimedia Phabricator team maintains the project, dealing with upstream bugs and high priority tasks.
* Our instance is upgraded regularly following a deployment plan that includes continuous integration of local patches.
* Plan agreed on local patches and relationship with upstream.
