When you are faced with a problem it is useful to stop and ask why five times. It is easy to do but few people do it.
This is a very simple yet very powerful technique. The aim is to ensure that a problem stays solved and never happens again. We do this by identifying and eliminating the root cause of the problem. When the root cause is eliminated the original problem is solved permanently.
This looks like an interesting technique, but I fear that the examples are somewhat contrived? I’ll have to try it out at work, and see if I get any interesting results…
