Well, to some degree, Andy. I have seen a number of companies, especially small companies, where registration was just an added cost and a loss of at least a day a year (usually a few more days) of a lot of work not done as a registrar is auditing. Wasted time. Registration did not affect nonconformance events or improvement aspects.
I've encountered too many small businesses where entrepreneurs seem to measure success by how far they've come, rather than how much they need to improve.
I
rarely saw that. Quite the opposite. "How far they've come" IS a "measurable", but the important measurements are growth and profit.
Then again, I don't doubt many "entrepreneurs" do not have any or much business experience. Even there, though, anyone starting a business has to learn "business 101". That said, I don't see ISO 9001, or any other standard, as a way to learn business "best practices".
I have also worked with some small companies which truly did not WANT to expand. They liked the company as it was/is - Small, family oriented, happy with no plans to expand. One of the companies has been in business since the 1940's and the "newest" employee had been hired something like 10 years ago. Want to talk about a great place to work... Plus - Singe day shift, and quitting time was just that (never any overtime, so employees had "family time").
