The Three Ways Explained
The Phoenix Project, by Gene Kim, Kevin Behr, and George Spaffoed, has been my most recommended book of the past several years. This is from the appendix which explains one of the key frameworks of the book:
The First Way is about the left-to-right flow of work from Development to IT Operations to the customer. In order to maximize flow, we need small batch sizes and intervals of work, never passing defects to downstream work centers, and to constantly optimize for the global goals…
The Second Way is about the constant flow of fast feedback from right-to-left at all stages of the value stream, amplifying it to ensure that we can prevent problems from happening again or enable faster detection and recovery. By doing this, we create quality at the source, creating or embedding knowledge where we need it.
The Third Way is about creating a culture that fosters two things: continual experimentation, which requires taking risks and learning from success and failure, and understanding that repetition and practice is the prerequisite to mastery.
