Do you have documentation that describes product specific manufacturing processes, inspections and tests that are performed including the order and references to the procedures and instructions? If the answer is yes, then this is a quality plan. Also look at ISO 90001:2000/ISO 13485:2003 7.1 Planning of product realization, note 1. The quality plan they are looking for is product specific, while your QA manual is general. Therefore, you would have a different plan for different products or product families.
I agree. GMP do not require you must have a quality manual, but instead requires for quality plan, so quality plan have more interpretations than it in ISO13485 and ISO 9001, document defines the quality practices, resources,and activities relevant to general and specific device that are designed and manufactured can be referred as quality plan, so there your quality manual is general device quality plan, and if you have specific device that do not follow the quality manual, you must establish another one.
ISO13485 and ISO 9001 require you establish quality manual for general device, and not referred quality manual as quality plan, but interpreted quality plan as : a document specifying the processes of the quality management system (including the product realization processes) and the resources to be applied to a
specific product, project or contract. so if you have a specific device that not follow the quality manual, and you establish a document defines the quality practices, resources,and activities relevant to this specific device that are designed and manufactured ,this document can be called as quality plan in ISO13485 and ISO 9001.
