It’s a fun, light read, and maybe points the way to new mechanisms for describing SAFe adoption “from the inside out.” The nice thing about this format is the ability to see and feel the people and cultural aspects of SAFe, because as a framework, it is just that, and it’s the people that do ALL the work.
