Moving to Mobile

Facebook's Web front-end release process has evolved into a large-scale pseudo-continuous deployment system where we release anywhere from 30 to 300 changes per push, twice a day, coming from around 1000 developers in 4 distributed engineering offices. What lessons did we take from our successful web deployments when we made the shift to a mobile-centric company? We'll discuss how we managed to keep features of our fast-flowing development and release process and apply them to the very different world of mobile release, which is essentially a shift back to packaged software. We'll describe how we maintain a date-based release schedule, how we test and collect mobile metrics, and describe the real-world issues of dealing with package deployment and end-user uptake.
