I recently finished Bulletproof Problem Solving: The One Skill That Changes Everything (Charles Conn, Robert McLean, 2019, 320 pages). This is not a groundbreaking book, but I consider it a good discussion about modern problem-solving techniques.
If you are familiar with different modern approaches to solving different kinds of problems, this book may not have too much new to add. Except from some interesting examples, and anecdotal stories that follow.
However, if you are new to things like design thinking, strategy consultancy methods, statistical data analysis, etc. this book may be a good general introduction, and a step-by-step guide. With the advantage that it is up-to-date with the most modern methods in use today, including Machine Learning modelling.
In my case, I have already read about and professionally practiced different techniques presented on the book. Still, I considered it interesting as a refreshener and as a good discussion on how to methodically approach different kinds of problem, with the steps that can be taken to create hypothesis, collect data, prove or disprove ideas, and communicate possible solutions.
If this sounds interesting, in addition to some good examples of problem-solving in practice, the book may be a good fit for you.
