Possibly, but I think a lot of the jargon and ten-dollar words associated with the subject are a serious barrier. People won't willingly adopt methods they don't understand. I look at it this way, and I think this is simple enough for everyone to understand. It may not be logically rigorous, and it's certainly unstructured, but you can comprehend it and adopt it NOW, if you so wish. We have Murphy's Law, which can be stated as 'Anything that can go wrong, will.' Then we have Woodgate's corollary, 'Anything that apparently can't go wrong, actually can.' So, what you have to do is look at the product, with mind engaged, and I mean the actual physical product there in front of you, and think of a big notice in red flashing letters, that says 'What really COULD go wrong?' Many times, in doing a product assessment, I've astonished the client by disclosing quite serious issues, using this method. It's much easier for a person not closely associated with the design team (but preferably not a total stranger, for social reasons) to do this. Of course, the design team should use the method as well, but they have to accept that they may not see the wood for the individual trees they've grown to know and love. It is obvious that this first step, 'identification' is crucial. If you don't see the issue, you can't apply any methodology, however sophisticated, to it. And very often, the best, trial second step is 'eliminate', because it often costs very little or even nothing. There is usually no point in conducting a 1000 dollar analysis to save a single cent. Occasionally, elimination can even involve a cost-saving (e.g. using rivets instead of screws that might loosen, or be left out after repair)! -- OOO - Own Opinions Only.
