Nice post! I enjoyed reading about how many teams were involved in the process. CI has to be a collaborative effort to be really successful.

It's often underestimated how much benefit you'll get from taking a good look at your cache usage. It all worked great the day your platform team set up the build system, but 100 new CI jobs later there will be tons of room for improvement. Similar story with consolidating CI jobs in general. If we keep just tacking things on eventually we have to step back and optimize.
