Your problem isn't with making the product and your solution will not be preventive. Your problem lies with meeting this requirement and your solution has to reside here.

a) product requirements are defined,
b) contract or order requirements differing from those previously expressed are resolved, and
c) the organization has the ability to meet the defined requirements.
Records of the results of the review and actions arising from the review shall be maintained (see 4.2.4).
