The organization plans, sets up, runs and keeps an audit programme, covering how often audits happen, the methods used, who is responsible, consultation, planning requirements and reporting, with regard to how important the processes involved are and what earlier audits found. It sets the criteria and scope of every audit; chooses auditors and runs audits so that they are objective and impartial; makes sure results reach the relevant managers, workers and their representatives, and other relevant interested parties; acts on nonconformities and to keep improving its OH&S performance; and keeps documented information as evidence.
This control maps to 44 controls across 26 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
