During a system audit it will be determined whether the validation has been correctly performed and documented and whether the system works in a way that demonstrates the system is under control. This includes the check of internal requirements for validation (QMS for IT).

The goal is not only to provide confirmation of formal correctness, it is also to highlight practical hints and suggestions for reducing the effort for future activities.

An audit of the project management approach is also valuable for identifying potential improvement opportunities.

The objective of a supplier's audit is primarily to provide confirmation of the quality and compliance of a product or service. Additionally, through the findings of the supplier audit, it is possible to adapt the validation approach according to the quality of the supplier.
