Plant Layout - Have a copy to give them for planning.
Number of shifts and employees per shift - What shifts will be audited? What hours?
Pre-assessment Audit? - If so, Scope. I prefer the preassessment to be limited to an in-house document and systems review (Quality Manual, all tier [level] 2’s and any related documentation). My concern is less ‘are the folks following documentation’ than ‘is the documentation and are the systems acceptable’ to the registrar. We can assure the folks are following documentation internally. Note: One company I spoke with charged for a Pre-assessment whether you had one or not. I was told that if they did not do a pre-assessment they would have to spend more time during the registration assessment. - NOTE: Documentation failure is the most common registration failure mode.
DoD and other Sensitive Areas - Make sure everyone agrees on how they will address the ‘Secret’ / ‘Top Secret’ aspects of your company’s business. This will probably be a function of scope.
