Roadmap

Background: In recent years, Wikimedia Foundation's engineering planning has primarily taken place in a combination of internal goals documents and public project-level documentation. The purpose of this page is to establish a practice of sharing holistic engineering goals, initially primarily with a short term horizon, as a public document with open participation.

Editor Engagement Experimentation (E3)

 * This new team focused on engineering for experimentation around strategies to reverse stagnating/declining participation in Wikimedia’s projects. This team is cross-functional with resources from the Community and Engineering/Product departments tasked specifically with conducting small, rapid experiments designed to improve editor retention. The experiments product backlog will be published by the team on a public wiki (meta or en.wp) and the technical documentation will be published on mediawiki.org for all experimental features.
