The Fallacy of Move Fast and Break Things: An Argument For Psychological Safety

Conference
Build & Deploy

The phrase “move fast and break things” has echoed in halls of tech companies for years. While it may sound like a good approach, without processes in place to set teams and individuals up for success, challenges will be faced. You may be thinking “Ugh processes - they stifle innovation, slow things down, and introduce unnecessary hurdles.” But in order to move quickly and know what to do when things break, processes are needed for:

  • Releasing a new feature to production. 
  • How and when is code deployed?
  • What's the path to production—are features first made available to internal users, then a gradual rollout to all users?
  • Alerting and notifying the correct individuals that something is broken
  • Implementing safety precautions. 
  • What precautions can be implemented to safely disable or roll back features when something breaks?


Moving fast, breaking things, and taking forever to resolve problems does not result in happy customers or employees. High performing organisations move quickly and break things, but they also have a relatively low MTTR (mean time to resolve) when things break. The longer it takes to resolve an incident the unhappier people are. This talk will explore what processes to put in place to reduce MTTR such as:

  • Scheduling chaos or game days to practice what to do when things go wrong
  • Setting up the right monitoring strategy
  • Testing in production


You can attempt to move fast and break things - but only when you have the right protections and processes in place.
