I just finished reading this book. I picked it because I wanted to find a different perspective about strategy and some of the posts I have read in Medium from the author where appealing to me.

I have enjoyed a lot the issues they faced during the period of work in Procter & Gamble with A.G. Lafley, the company is very well known in US and I have been understood better how they work and how they make decisions is a very tough industry.
In words of Roger Martin, the role of a consultant is not to attempt to convince clients which choice is best; instead run a process that enables them to convince themselves.
Other important fact: in strategy, there are no absolute answers or sure things, and nothing last forever.
