How to use it?
7 steps to use Pugh Matrix:
- Step#1: Construct a Pugh Matrix template using a Microsoft Excel spreadsheet. Start by writing the criteria in the first column and the options in the top row. List as many options as you need.
- Step#2: Create criteria to evaluate feasible solutions. It can include cost, maintainability, feasibility, long term benefit, availability of resources, etc.
- Step#3: Assign scores for each criteria using comparative significance. The benefit of customers should be the priority when allocating scores to every criterion.
“Alternatives are assigned scores with respect to the criteria. The most likely option will be selected based on the overall scores. For a reliable outcome, scores should be assigned based on data collected and facts.”
