Caveat Emptor

I have opinions. Often, these opinions are strong; and, in most cases, these opinions are strongly held. But, they are just my opinions. In this book, I will speak with an air of authority because I believe deeply in what I am saying based on what I have seen: a team transformed. But, what I am saying is based on my own experience, context, and organizational constraints. What I say may not always apply perfectly to you and your situation.

You are a discerning, creative person. You are here because you're enrolled in the work of building better products; of building more effective teams; and, of delivering more value to your customers. Do not let that creativity take a back seat as you read this book. Be critical, but open-minded; question my assertions, but do not dismiss them out of hand.

Feature flags are a deceptively simple concept. It can be hard to understand the extent of the impact they have on your team because the implications aren't only technical. If all you learn from this book is how to use feature flags as a means to control flow within your software, this book will be worth reading. However, the true value of what I'm sharing here lies in the holistic cultural change that feature flags can bring to every part of your product development life-cycle.

This book does not represent an all-or-nothing approach to product development. But, I do believe that the more you take from this book, the more you will get.
