Agile Transformation - Chef or Cook?
As an analogy, if you want to learn about Agile Transformation then prepare to become a chef, not a cook. A cook is able to follow instructions from a recipe and repeat a process that has already been done many times before. This works well when the outcome is known and the process (cooking, in this case) is simple. Chefs, however, can follow procedures and processes in an expert manner (and often do so, when appropriate), but they also understand the fundamental reasoning behind the instructions and can adjust the process to create their own recipes when the context changes. Chefs ultimately write their own cookbooks.
