A Management Review is a formal meeting where senior management evaluate the effectiveness of the ISO management system. It is usually held annually, but more frequent reviews can add value.
In terms of what should be covered in a Management Review.
If Citation ISO produced your Management System, this will be documented in your Management Review procedure.
If you obtained your Management System externally, then you will need to ensure the mandated ISO requirements are covered to be compliant.
Senior leadership, quality or compliance managers, and key process owners should attend the Management Review.
It's key that these should be attended by those with the authority to make decisions and commit resources.
