Determine the scope of an audit program

As a management system manager, you need to draw up or update a schedule for internal audits of your management system.

Ideally, you'd like to audit all the company's activities and processes every year (audit domain), at all the sites where these activities are carried out (audit perimeter). In practice, however, this is often out of reach, due to a lack of resources (auditors) and the availability of those being audited.

Ultimately, the aim is to find an empirical optimum between the number of audits and the existing potential for improvement. To achieve this, several parameters can be taken into account, as detailed in this data sheet.
