Any evaluation used to support decision-making or planned for wide distribution should include a peer review to ensure product quality. Two types of peer review have been widely used and provide different types of support:

• in-process peer review/steering committee;

• independent peer review of the completed analysis.

In-process peer review brings an expert group of practitioners and decision-makers into the process at regular intervals — perhaps once per quarter — to be briefed on the status of work and any known problem areas. Independent peer review allows objectivity through review of the finished product by independent outside experts who have not been involved in the evaluation. Both types of peer review have a potential role in proliferation resistance analysis.
