Ashby's law is a good introduction to dealing with complexity. This book has lots of ways of asking questions that will let you come to an understanding if your problem is complex and how to go about it.

Cracking Complexity, more like Cracking Common Sense.

I was wishing that there would be groundbreaking new information that I have never heard before in my entire life but this book did not even come close to achieving that.

This is just common sense business stuff that everyone knows, repackaged into a book.

For a book about cracking complexity, this book was repetitive and overly complex.

I didn't enjoy this book.
