Audits are conducted as part of an internal audit programme which is managed by the Quality Manager.

The documents within the QMS, the processes outlined in the documents and the final test results are examined during the audit.

Problems within the system are usually identified and must be resolved using the corrective action program. In most cases the QMS documentation will need to be altered to prevent the problem from recurring.

At other times audits may be conducted in response to a problem within the system. These unscheduled audits aim to fix the problem and improved the system to prevent recurrence.
