If deploying new code is stressful, then here are some tips to try... Improve your deploying until you feel it's easy, routine, pipelined, automatic, monitored, tested, and post-deploy tracked so it's provably working. Good practical ways to start on this path can include devops, IaC, E2E testing, etc. Then get good at tactics such as rainbow rollouts, blue-green, canaries, feature flags, dark launch, self-throttling capabilities, and self-healing systems. A simple example is to deploy to 1% of people, and when incoming metrics prove success, then increase the percentage. Success looks like fearless deployments. Some teamwork ideas to try are group ownership, blameless incident responses, causal analysis based on system theory (CAST), service level agreements with stakeholders, and specific software quality attributes for availability, recoverability, and the like.
