Typically arranged as a table, each option is scored relative to each criterion (sometimes using a simple scale like +1, 0, –1 where +1 means better than a baseline, 0 means equal, –1 means worse, or using numeric scores). If weights are used, scores are multiplied by the weight of that criterion. Finally, the scores for each option are summed (yielding a weighted total if applicable). The matrix layout allows decision-makers to see where each option has advantages or disadvantages, and the total scores indicate which option performs best overall. For example, in selecting a supplier, criteria might include cost, quality, and delivery time with weights reflecting their priority. After scoring suppliers A, B, C on each, the Pugh matrix would clearly show which supplier has the highest total (and in which areas each supplier is strong or weak).
