Thanks for this comparison. I've read both GS/BS and PTW and like your language better than Rumelt's for many of the reasons you've described. The one thing that I found was that there is no explicit mention of anything equivalent of a Diagnosis in your framework. I know you advocate for it...i.e the Dewey quote...but I'm curious why you didn't make something equivalent to the Diagnosis (or Problem Context or whatever) explicit as a starting point in your strategy model? Asking out of curiosity as I put that (I called it Problem Context or Market Situation depending on the objective) as an explicit first step to consider.
