The Unicorn Project Book Review

When I first heard about The Unicorn Project I have to admit I was disappointed, I’ve long been a evangelist for Gene Kim’s book The Phoenix Project but I’d just spent months working on my own development DevOps book, Code Black.

I shouldn’t have worried, I really enjoyed The Unicorn Project and we’d gone down different angles. Where I’d focused more on the Continuous Deployment journey Kim’s book focuses much more on developer empowerment and continuous experimentation.

The story follows Maxine, the developer who caused the now legendary payroll outage at Parts Unlimited towards the start of The Phoenix Project. Exiled to the documentation team as punishment she’s instructed to support the Phoenix rollout but quickly realised how woefully under supported the engineering teams are. As the business piles on more and more pressure, expects more features, and has less and less appreciation for the technical debt they’re wracking up they continue. Until, as we know the entire project explodes.

Working with some familiar characters such as Bill, Brent, Erik, and Maggie and a few new ones including Cranky Dave and Kurt our heroine works to make life better for the entire company. These are the engineers, the red-shirts, not the bridge crew. They’re the ones who actually do the work and they’ve got a lot of it to do!

What did I like best? Kim put lots of emphasis on testing and improving the entire system not just a small part of it, he focuses on collaboration and the importance of making it easy to onboard developers and share knowledge, and really drives the need to innovate and out experiment the competition. He also emphasis the importance of treating engineering tools as important systems and draws distinctions between the IT products we build, and the miscellaneous ones which just keep the lights on.

What wasn’t so good? Within a few chapters I was absolutely sick of Erik’s use of the word “sensei”… seriously can’t some of the people he quotes simply be experts, evangelists, or even gurus!?

On a more practical point the book spends a lot of time evangelising functional programming and scalability technologies. Which is great, they’re very powerful tools. But one of the things I liked so much about The Phoenix Project was how it was clear the team were struggling the same tech debt we all are. It made it more relatable and I worry in this book Kim’s “rip it out and use the latest and greatest” will overpower his more generic messages of continuous incremental improvement. Perhaps it’s personal preference but I like my DevOps books technology agnostic.

So, would I recommend this book? Absolutely without question! I believe that The Unicorn Project will take its place alongside its elder sister on the bookshelves of developers, testers, managers, product owners, and operational engineers for the next decade. If you haven’t already go and buy it, any while you’re at it not get a copy of Code Black too!? 🤣
