Material record approval

Collect the answered material questions into the purchasing brief. Ask the responsible reviewer to resolve any differences between component descriptions and quotation wording.

Use material review record to separate the questions assigned to each project reviewer and the documents needed to answer them. Connect each open question with the proposed item or stage it affects. Ask for a response addressing those questions individually, and have the responsible reviewer record the agreed description that the purchasing team should use when it prepares the request for commercial terms. Ask the assigned reviewer to distinguish a request for more information from approval of the proposed item, so that open questions remain clear.
