I am now working through the revised edition as one complete book rather than a collection of separate chapters. Every chapter can sound perfectly reasonable on its own and the book can still fail to add up.
I am checking that the Card, the rounds, the board, the decision trail, and the thirty-day trial describe one method from beginning to end. The diagrams have to explain something. The notes have to earn their place. Most importantly, the finished book still has to sound like the person who wrote it. If a paragraph begins to sound like a consultant presenting a maturity model, it goes back on the bench.
