A quick search on the OASIS database shows that, out of the universe of 20,519 site certifications, 17,801 are to the 2016 editions of the AS91X0 standards. So, close to 87% of the certificates have been transitioned.
Let's remember that many sites have probably been through their transition audits, but certificates have not been issued yet.
As for the statistics of the nonconformities during the transition, I am always skeptical about the results. In my experience, when auditors are asked to audit against new versions of standards, despite having been "trained", they tend to drift into their comfort zones and avoid auditing "subjective" requirements.
Another thing about CB auditor NC statistics. Deming used to say that a very high percentage of quality problems had to do with ineffective management. Most quality professionals tend to agree with that assertion. Still, when you correlate CB NC stats with the standards, we realize that very few nonconformities are referenced to top management failures. In my opinion, that is an area where CB auditors (those who have the courage and the caliber to do it) should improve. Problem is: top management when exposed as the source of system problems might invoke his/her authority and demand a change in auditor and/or CB...How dare they?
