Stage 1 and stage 2 for the internal audit?

Answer:
The stage 1 (and stage 2), typically is only for the certification audit (third party audit), and before it you only need to perform the internal audit. You can do the review during the internal audit, and assess that documented information is completed and managed in a compliant way, so you do not need to perform the internal audit dividing it into 2 parts, I mean, you only need to perform an stage to review all documents and to review the compliance with the standard.
