The Phoenix Project is a fiction novel about an IT department for a large car company that experiences management dysfunction and battles frequent technical debt, but ultimately overcomes it by adopting the best practices of DevOps.
I first read its non-fiction companion book, the DevOps Handbook, which got me drinking the Kool-Aid, but this is also a wonderful, breezy read (no small feat for such a technical topic) that is an even more gentle introduction.
Not only did these two books make me come to appreciate DevOps, they also taught me about Kaizen and Toyota Production Model, which DevOps began as a software translation of. Subsequently, I have also applied these principles to the field of screenwriting.
