Much of my teaching is focused on how to effectively define a problem, how to go about solving it using discipline and various techniques and then how to frame to recommendations so that others will take action. I have written on this in the past as well.
Too many books I see on the problem solving side take an overly complicated approach, particularly for readers trying to go from “not so good” to “pretty good/good”. The typical tome is much more of an expert practitioners guide and makes things more complicated than they need to be.
I really appreciate Problem Solving 101: A Simple Book for Smart People because it doesn’t fall into this trap. It takes a light-hearted and practical approach to demonstrating a simple but powerful set of basic tools.
Ken Watanabe worked for McKinsey, a leading strategy consulting firm. He distills the basic components of theirs (and everyone else’s) basic problem solving structure into problem definition, analysis structure and solution definition. He does this using a few simple (but not simple-minded) examples that were originally developed for 6th graders. It’s a very quick read (digestible in a short plane flight) , useful and worth a read whatever level of skill you believe yourself to be.
