Ensure you understand all of your internal and external requirements and have considered these in the development of the system.
(a) Internal Requirements
Internal requirements include the organisational structure, responsibilities, relationships with clients and suppliers, existing policies, procedures and other management systems that may already be in place such as a safety or environmental management system. It also includes defining a scope for the system. The scope defines what is included and potentially excluded from the governance of the system. Will the scope include all processes at all sites and all subsidiary companies or are there valid reasons to exclude some things from the system.
(b) External Requirements
External requirements obviously includes the Quality Management Standard ISO 9001, but includes other regulatory and legislative requirements, industry requirements or other voluntary guidelines that you may subscribe to and requirements set down by your clients or government.
