As things move forward with generative AI - lets look at where are we with strategy.
As a start let's have a look at the ChatGPT response to strategy (just below).
So the good news is to accomplish the first step of getting an outline and some guidance on the key elements of strategy, you don't need a $150 textbook, you don't need to sit in one of my MBA classes (though they are relatively fun). The AI of your choice, most likely will produce this for you.
The challenge is, while good - this is just information; decidedly different from knowledge, and experience. You probably saw this coming, but I help with the knowledge.
