No, and you haven't answered the question either. In cases in point, the "intended benefit" was realized when the customer requirement was satisfied, and it continues to be realized as the certification is maintained.
Let's not try to rewrite history with with florid marketing language. The ISO 9001 registration feeding frenzy began in the early 90s when companies were led to believe (initially by opportunistic consultants, abetted somewhat by CBs) that they would be locked out of the EU market without it. I know--I was there. It became a "common customer request" in the (demonstrably) misbegotten belief that ISO 9001 registration would lead to the things you say it should lead to. It hasn't led to those things. In essence, nothing changed except the further crumbling of American manufacturing.
Jim, we've gone round and round on this topic. We have a different point of view. My point of view is based on working with a couple hundred companies. I have reported what they told me, often in unguarded moments. It is further supported from what we all hear and see in industry magazine articles and other sources.
There are a million companies certified to ISO 9001. Early on, there was a belief that European customers would require it, and many of them did. There was an even bigger driver in the USA, when Detroit based automotive customer made it a requirement.
The reason many customers made it a requirement was the expectation that theiir sppliers would improve as a result. And, by and large, they did. That is not rewriting history, amigo, that is just stating it as it is.
Sure, some companies only wanted a certificate, they were required to do it by their customers. They spent the money and got a framed cert, and not much else. But, you can't seriously argue that all 1,000,000 of them only did it to get a cert, and don't seriously make an effort to use it daily to improve. 30 to 50% of them? Maybe, I'd give you that much. But the other half clearly try to work their systems and use them to the best of their ability.
When I work with 250 companies, 80-90% have put forth true effort to work theiir systems and apply what we are telling them. We work with them over the years and see the changes. They tell me how they are using their systems. They take pages of notes without anyone telling them they have to.
Or, maybe I am just a lucky auditor, and all my clients take this seriously, and the other 999,750 certified companies are just giving it lip service...
C'mon... That is not serious. That is a cynical point of view, and there is too little other than anecdotal observations to back it up.
Companies fall into 3 categories - some really work their systems and take it seriously. Their performance clearly shows dramatic improvement, concurrent with their implementations.
The second group does put some effort forward, but have inconsistent buy-in, and somewhat reduced support from top management. These companies tend to see some definite improvement, but the correlation is less clear.
The 3rd group bought a certificate, do not understand it well, and do the minimum needed to keep the cert in force. They have little to show for it, but they get quote opportunities because they have a cert.
I feel sorry for the 3rd group, but it is a free country, and they are permitted to do that. However, it not fair nor statistically valid to take that 3rd group and extrapolate a viewpoint that paints the entire certified base of companies.
I agree with a lot of your posts, but on this one I have to agree with Andy. You have a cynical and biased point of view on this topic of "benefits of ISO," developed earlier on, and I think it seriously colors your perspective when it comes to certification. I think you have stopped looking for evidence to support a different conclusion.
Your view is your prerogative, but I don't think the collective history of 1,000,000 companies suppports your point of view. Maybe 25% of it is as poor as you describe. The rest perform better at many various levels.
Too bad for them, but it is their money.
