Summary

In this chapter, we discussed how decoupling deployment from release allows self-sufficient, full-stack teams to shift deployments all the way to the left on the timeline. This helps to minimize risk and increase throughput by deploying small batch sizes, and ultimately delivers features by enabling feature flags for targeted groups of users. Decoupling deployment from release requires multiple levels of planning. The release roadmap defines how the desired functionality is divided into slices. Each slice is designed as an experiment to elicit feedback from customers about the correctness of the value proposition. A deployment roadmap defines the ordered set of tasks needed to implement a specific story as a series of task branch workflows. We discussed how a task branch workflow governs an individual instance of a deployment pipeline that is implemented using a modern...
