Simple Root Cause Analysis

Five Whys

bq. 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.

bq. 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…

    Don’t you run into the “Why?” mental block with the kids? Curiously, my kids don’t ask about why computers do what they do. They associate different shows & programs with “CDs” and that seems to be enough understanding for them.

    Gone are the days when you could see pixels, had to look at symbols, imagine color or had enough time to defeat the copy protection… :)
