If technical experts are used to evaluate certain features, they receive only those proposal sections dealing with their issues. Proposals are then evaluated and scores are computed for each of the predefined criteria. Proposals may be ranked, and only those capable of providing an acceptable solution receive further evaluation. There is no universally accepted scoring system. Most use points, although some are based on descriptive words or colors.
Some points systems incorporate a predefined set of features, each with a corresponding score.
Other systems use qualitative measures. For example, a supplier receives five out of a possible 10 points if its proposal satisfies the minimum set of requirements and contains only minor deficiencies. More detailed evaluations may incorporate demonstrations or presentations, site visits and reference checks. Once evaluators have determined the best proposal, contract negotiations start. Failure to negotiate an acceptable contract within a predefined time is reason to reject a proposal and consider the next best.
