The stakeholders whose needs and expectations a management system must consider, such as customers, regulators, employees, and suppliers.
Interested parties, also called stakeholders, are any individuals or organizations that can affect, be affected by, or perceive themselves to be affected by the management system. Typical examples include customers, regulators, owners, employees, and suppliers.
ISO standards require an organization to identify its relevant interested parties and their requirements, because those requirements become inputs the system must meet.
