ICAM Investigation Course
I did ICAM with IMPAC 6 years ago, it was worth doing because of the excellent presenter (Frank McCutcheon).
I often hear 'ICAM' bandied about as it was a kit-set surefire way to undertake a successful investigation, like doing a jigsaw puzzle. This can be (and often is) far from the truth. ICAM is just one tool.
Whenever I hear the phrase 'root cause' I get an internal shudder (similar to when I hear 'common sense'). Both of these phrases are oxymorons.
