In order to remain ISO 9000 compliant, an organization must maintain the structure of the Quality Management System (QMS).
The five pillars of the QMS structure are:
A statement of the goals of the organization with respect to
its Quality Management System.
The details of the QMS, including the specific processes,
procedures and staff responsibilities.
The actual instructions for performing tasks that
affect the quality standards of the organization.
Documents that demonstrate conformance to the specified
requirements of the QMS.
Corrective Action Requests
Controlled documents that specify how problems with the
organization’s QMS are to be fixed.
