7.1? You audit the Product Realization clauses to show conformance to 7.1 you don't audit it specifically.
The only way to verify conformance to 7.1 would be to audit everything between 7.2 and 7.6. Clause 7.1 is a general clause that is broken down into greater and more specific detail in the clauses that follow it.
7.1 Planning of product realization
The organization shall plan and develop the processes needed for product realization. Planning of product realization shall be consistent with the requirements of the other processes of the quality management system (see 4.1).
In planning product realization, the organization shall determine the following, as appropriate:
a) quality objectives and requirements for the product;
b) the need to establish processes, documents, and provide resources specific to the product;
c) required verification, validation, monitoring, inspection and test activities specific to the product and the criteria for product acceptance;
d) records needed to provide evidence that the realization processes and resulting product meet requirements (see 4.2.4).
The output of this planning shall be in a form suitable for the organization's method of operations.
NOTE 1 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, can be referred to as a quality plan.
NOTE 2 The organization may also apply the requirements given in 7.3 to the development of product realization processes.
