Pugh Method for Evaluating Design Alternatives Step 1: Identify a set of criteria describing the needs and wants of the customer. Step 2: Select a baseline solution. An existing product is often used as a baseline. Step 3: Compare the options with the baseline as better (+), worse (-), or the same (0). Step 4: Make a decision. The design alternative with the highest score may be selected. Identify your favorite features in the lower scoring design alternatives. See if you can find a way to bring all of your favorite features into your chosen design. Step 5: Repeat steps 3 and 4 until you are satisfied!
