Coming Soon: Feature Flags - From Concept To Cultural Revolution

By
Published in Comments (8)

In my tenure as a co-founder and principal engineer at InVision, I went from never having heard of "Feature Flags" (aka "feature toggles" aka "feature switches"); to seeing them become widely adopted by our engineering team; to witnessing a complete cultural revolution in regard to how our company approached product development. For me, feature flags are as transformational as databases — they are as important as both logs and metrics. I cannot imagine creating another product without them.

I believe that I have a perspective worth sharing. I want to help people see the magic that I see. I want to help teams deliver value to their customers with love and empathy and without fear. As such, I'm going to try my hand at writing a book on the matter. This book will be highly opinionated; and will be colored by my own hands-on experience in seeing what works and what doesn't work.

This book is very much a work in progress! If you want to know more about the progress, you can subscribe for updates on the book's mini-site:

I don't anticipate this book being very long. Feature flags are a relatively simple concept that provides massive leverage. I'm hoping to get this done rather quickly.

I think it's great that you're writing a book. The wife wrote a couple, I co-wrote one with her. (Non-technical content.) It's very rewarding! Maybe not a path to riches, but I don't think that's always a goal!

@Will,

Yeah, I don't expect this to be a "money" thing. I'm not even entirely sure if I want to charge for it (though, much that contention is tied up in impostor syndrome). I figured I just need to start writing and then see how it ends up feeling. Right now, I'm still in the bulleted-lists / brain-storming mode.

@Andrew,

Thanks for the link -- will take a look. I did read Adam's Refactoring UI book (which is a great book, by the way). I think this might be the same book, not sure. Anyway, Adam clearly knows what he's doing - I'll be sure to glean as much information as I can from him!

I've followed your blog for a long time, love the working code podcast, and am stoked to read the book. Your thoughts on feature flags have opened my eyes to new possibilities already. I hope writing it is a great experience for you!

@Mike, @Jacob,

Thank you for the positive encouragement! I really hope that I'm able to take the love that I have for feature flags and communicate that in the book.

@All,

I'm super excited to announce that I have an EARLY ACCESS version of the book available. This is a PDF version, and is a bit rough around the edges. But, the content is there and it's 50% off. If you get the early access version, you'll automatically get access to future versions as well.

Check it out at https://featureflagsbook.com/

Oh man, I can't wait to get back to blogging again 😂 😂

I believe in love. I believe in compassion. I believe in human rights. I believe that we can afford to give more of these gifts to the world around us because it costs us nothing to be decent and kind and understanding. And, I want you to know that when you land on this site, you are accepted for who you are, no matter how you identify, what truths you live, or whatever kind of goofy shit makes you feel alive! Rock on with your bad self!
