Advantages of Pugh Methods. Start by writing the criteria in the left hand column and the alternatives in the top row. The unweighted decision matrix, which doesn’t use an assumed weight scale to identify the best option. Choose or develop the criteria for comparison. The Pugh Matrix, designed by Professor Stuart Pugh, answers the question, “Which option will most improve what is in place now?” by including a baseline in the calculations used to weigh comparative criteria. The Pugh Matrix is not intended to be a mathematical matrix; it is simply a format for expressing ideas and the criteria for the evaluation of these ideas in a visible, user-friendly fashion. Looking at the tally totals at the bottom of the matrix, we see that pizza delivery has two pluses, one minus, and one S. Factoring in relative weights of the criteria, we see that pizza delivery is still the best option when weighted, at six pluses and two minuses. The analysis covers 181 All rights reserved.
