Categories: Business & Money, Self-Help

Are Your Lights On? is a short, playful classic on problem solving by Donald C. Gause and Gerald M. Weinberg, first published in 1982. Through illustrated stories and puzzles, the authors show that most failures come from solving the wrong problem. They teach readers to ask what the problem really is, whose problem it is, where it came from and whether it should be solved at all. The book has long been a favorite of programmers, managers and consultants.
