Laura & ST have been supporting individuals, teams and companies in (agile) change projects for many years. Sometimes this has been very disappointing and frustrating. As a self-therapeutic measure, they began to write short messages in which they satirized or simply quoted their environment. Comments like: "You can do that any way you like, but not like that" or "Testing? We don't do that, it's far too expensive. We implement changes live" or "This is a very good method, but unfortunately it doesn't work for us" or "In the time planning takes, I can also work on something for real" brightened the depressed mood. In the course of time, small drawings were added and the idea for this book was born. To make sure the content is not only negatively connotated, they have described improvement suggestions with each anti-tip.
