Feature Flags Book: Ownership Boundaries

Feature flags are an implementation detail for engineering teams. As such, each feature flag belongs to the engineering team that created it. If we were talking about any other low-level algorithmic decision, this sense of ownership would be self-evident; and, we wouldn't need to have this discussion. However, since feature flags can be both observed and configured outside of the application itself, it's easy for people to misunderstand where the boundaries must be drawn.

In 2023, I published a book titled, "Feature Flags: Transform Your Product Development Workflow". This book contains everything that I've learned over the last 7 years about integrating feature flags into my product development. But, a static book can only take you so far. In an effort to make the book more interactive, I've created a series of blog posts—one per chapter—that provide a place in which the readers and I can discuss the content. You can purchase the book and / or read a preview of each chapter on the book's mini-site. Feel free to leave a question or a comment down below.
