Agile

Engineering teams at WMF are "agile", frequently delivering improved features.

Some teams adopt "big A" Agile software development, formalizing this into engineers working on "stories" in planned sprints. They use Mingle, Trello and other tools to plan work.

Category:Wikimedia Foundation teams internals gives some insight into teams' approach.
