Green Book supplementary guidance: multi-criteria decision analysis

Supplementary guidance to the Green Book on weighting and scoring in decision analysis



This guide explains how multi-criteria decision analysis (or weighting and scoring) can be used to access a mix of both monetary and non-monetary benefits. The extent to which each option meets the identified criteria is measured, and explicit weights are given to each of the criteria to reflect their relative importance. Using this technique, options can be ranked and a preferred option identified.
