Impact

Movement

This project will enable us to increase developer efficiency by consolidating our code-review and project management tools into Phabricator.

Foundation

Additionally, this will reduce the maintenance overhead that is incurred by having separate code-review and project management tools.

KPI

• Q₀: By the end of Q2 we plan to have a system in place to manage Differential and Nodepool/Continuous Integration interaction, from the baseline of no system in place.
• Q₁: 0% of WMF deployed repositories (but not MediaWiki and Extensions) are managed in Gerrit.
• Q₂: 0% of WMF deployed repositories are managed in Gerrit.
