Most people don't understand the compliance. There's good and bad, but there's no going back once your industry (candle makers, software writers, barbers, whoever) adapts a standard it invariably becomes a tool of an authority.
Good: What I like about it is that our certifications increase accountability by encouraging recording mistakes. The "routine" of flagging mistakes and finding root causes and formalizing "corrective and preventative action" has been good and improved our company.
Bad: These standards are adapted by many companies in order to reduce competition, take away via consensus unique individual methods for doing things. They become almost like a "union", punishing individual innovation via auditors that view the world inside a "box". Uniqueness and innovation are an increased cost and risk to the third party auditor, and the auditor is ready to adapt the majority interpretation - which is usually to increase barrier of entry into the field of competiton.
