Re: Ts 16949 Cl 7.2.2
This is usually done by reviewing the customer's specifications, including written and drawings. It can also include requirements that are not specific to the product, for example requiring a lab be registered to ISO 17025.
Let us not forget that 7.2.2 also requires record keeping of this review; 188.8.131.52 requires a waiver process if certain requirements can't be met, and 184.108.40.206 requires a feasibility analysis that incorporates risk analysis.
