The Release Engineering Team skill matrix is an attempt to identify (and subsequently address) bus-factor problems within the team. It came out of the May 2015 RelEng team offsite before the Wikimedia Hackathon in France where the silo'd nature of the team was identified as a key problem to address.
Below is the latest revision of the skill matrix (historical).
2019-04[edit]
