Our organization is in the 26-45 employees category. Our initial certification audit (to the 2008 version of the standard) was 3 days total stage 1 and stage 2 combined. In the past our recertification audit has been 2 days, even the year we upgraded to the 2015 version of the standard. Our surveillance audit has always been 1 day. We are not a complex or high risk organization and we've had exactly 1 minor nonconformance in the entire certification experience (beginning in 2011). Our auditors routinely leave early handing us a completed preliminary report on the way out the door.
Now our registrar is claiming that they need an extra half day for surveillance audits and an extra full days for recerts. Given our history I do not see it. Looking at the IAF Audit Day Guidelines I only see recommendations for the initial audit - 4 days for an organization our size. Am I missing something? Unless it truly is mandated, I do not see any justification for the increase in audit days.
