KeyMaker-DVT: A Practical Guide to Building Robust Feature Flags for Safer Deployments

Feature flagging is one of the most powerful techniques for reducing risk and increasing velocity in software delivery. KeyMaker-DVT (short for Decision, Visibility, Targeting) is a pragmatic approach to designing feature-flag systems that are safe, testable, and easy to operate. This post explains the three pillars of KeyMaker-DVT, shows concrete design patterns, and gives an actionable checklist to implement or improve feature-flagging in your product.
