The book is clearly not a replacement for an MBA program, but it is a good refresher on common frameworks and topics. Having earned an MBA from a top program, I prefer some of the models specific to my professors, and I got more in-depth and useful critical thinking structures from my classes, but many of the basic "must know" items are covered decently here (e.g., Porter's Five forces, Steve Blank's entrepreneurship process, 4 Ps of marketing). What's missing is application, examples, and the stories, cases, and simulations that help these concepts stick. The visuals are nice, but it's hard to internalize these tools until you've used or practiced them. This is especially true with networking and leadership principles - and therein lies the real value of an MBA. It's a 1-2 year laboratory where you can try on new ways of thinking, behaving in teams, and approaching problems. If you really want to maximize the value of this or any similar business book, get together with friends or coworkers and put this knowledge into practice.
