Kindly guide me the requirement of Internal Audit clause coverage for the period of 3 years as per ISO 9001 2008 standard 1. Should all the clauses should be covered for each site location (under certification) in the Internal Audit per year or over the period of 3 internal audit cycle 2. All the clauses should be covered once in 3 year cycle, ensuring each process are covered 3. System wide process like HR, Measurements, Analysis, should be covered each year. Off course based on the risk and importance has to be considered which may effect the frequency for few process.
