Before undertaking to supply, the organization reviews: what the customer requires, delivery and post-delivery activities included; requirements the customer did not state but that are needed for the intended use; its own requirements; statutory and regulatory requirements; and any contract or order requirements that differ from what was stated before. Under 9100 the review is coordinated with the functions concerned, and where requirements cannot be met, or can be met only in part, a requirement acceptable to both sides is negotiated with the customer. Differences are resolved, unstated customer requirements are confirmed before the order is accepted, and records are kept of the review outcome and any new requirements.
