“Happily, there is an effective method to get to the heart of any problem called The Five Whys. You identify a problem and then drill down into The Five Whys behind it. I’ll give you are very simplistic example to illustrate how this works. Problem: My tea was cold. Why #1 The kettle didn’t heat the water. Why #2 There was no power. Why #3 The fuse in the plug was blown. Why #4 An incorrect fuse was being used. Why #5 The required fuse was not specified. Solution: We need to get the right fuse to use in the future.”
