A quality manual is the document that stablishes the organization’s intentions for operating the processes within the QMS. The quality manual may include policies for all areas of the company that affect its ability to deliver quality products and/or services and meet the requirements of the standard and customers. The quality manual is no longer mandatory in the lastest version of ISO 9001:2015.
The QMS documentation consists of different types of documents, such as quality policy, quality manual, procedures, work instructions, quality plans, and records. ISO 9001 requires some mandatory documents, such as quality policy or objectives and others that the organization can choose to develop, like the procedures.
A quality plan is a document that specify quality standards, resources, specifications, and the sequence of activities that relates to a specific product or service. For instance, a quality plan in a manufacturing company may include procedures that describe the processes of productions and responsabilities associated, such as product specifications,or applicable measurement standards.
