This document discusses how scaling teams to support big data growth at Yelp can negatively impact deployment speed due to an exponential increase in the probability of failures as the number of developers increases. It proposes service-oriented architecture and focusing on mean time to recovery rather than just preventing failures as ways to mitigate these risks and maintain rapid iteration. Continuous delivery, reliable but not exhaustive testing, and treating all processes as distributed are also recommended to support scaling teams while preserving deployment speed.
