If it was meant to be a guidebook with examples, why all the fuss about it? You don't see people worshipping Cooking for Dummies, so why are we so cult-y about Scrum or The Phoenix Project. What's with the weird zen/Kung fu kind of vibe of it, as if they have just discovered sliced fknin bread? Sadly, I genuinely think that for some people the Phoenix Project is an eye opener. Their enthusiasm on just discovering how to be a professional in the role they have been half assing for decades bugs the living crap out of me. To me, reading TPP felt like reading a patronizing self help book. I found it nauseating, shallow, bland, and anyone expressing even a tinge of enthusiasm about it feels like an affront to my sensibilities.
