Book Review: Four Types of Problems
DECEMBER 17, 2018
The title of Art Smalley’s new book, Four Types of Problems , is misleading. It doesn’t actually address four types of problems. Rather, it covers four types of problem solving. In that regards, it’s an excellent reference book that belongs on every bookshelf. Smalley starts with the hoariest example of root cause problem solving: the machine tool that stops working because of insufficient lubrication.
