I am most interested in the way he articulates the importance of separating the How from the What. I see this problem often with clients that get caught up in doing the same old stuff bigger, faster, or cheaper -- all without asking "What are we doing?".
It is an easy trap to fall into and we all have to get better at raising the red flag when we see it happening.
I am also interested in the heat maps -- more on that later (after I read the book).
