Big picture
Release Engineering is where our code quality efforts can be amplified. When we do things well, we start to see more responsive development with higher quality code. That is our mission.

What we want to accomplish:
 * More appreciation of, response to, and creation of tests in development
 * Better monitoring and reporting out of our development and deployment processes, especially test environments and pre-deployment
 * Reduce time between code being merged and being deployed
 * Provide information about software quality in a way that informs development and release decisions
 * Help WMF Engineering learn and adapt from experience
