Compare alternatives against a baseline using simple scoring. Rate each option as better (+), worse (−), or the same (0) for each criterion.
The Pugh Matrix (also called Pugh Method or Concept Screening) was developed by Stuart Pugh for comparing design concepts. It's simpler than weighted scoring because you only compare against a baseline.
Choose a reference option—often the current solution or the most familiar alternative.
Enter the other options you want to compare against the baseline.
List the factors that matter for your decision (cost, performance, ease of use, etc.).
Click each cell to cycle through + (better), − (worse), or 0 (same as baseline).
The option with the highest net score (positives minus negatives) is typically the strongest candidate.
The Pugh Matrix shines during early-stage decision making when you need to screen multiple concepts quickly. Engineers and designers frequently use it during brainstorming sessions to narrow down many ideas to a few promising candidates before investing in detailed analysis. It is fast enough to use in a meeting without extensive preparation.
This tool is ideal when you have a clear reference point, such as your current solution, a competitor's product, or a standard approach. The relative comparison format (+/0/-) is more intuitive than assigning absolute scores, especially when you lack precise data or when team members have varying levels of familiarity with the options.
Use the Pugh Matrix when you want to facilitate group discussion around tradeoffs. The simple scoring system makes it easy for cross-functional teams to participate, and disagreements about +/- ratings naturally surface different perspectives and assumptions that need to be resolved.
A mechanical engineering team compares five bracket designs against the current design, evaluating strength, weight, cost, and manufacturability to select the best candidate for prototyping.
A manufacturing team evaluates three proposed workflow changes against their current process, comparing cycle time, quality, training requirements, and implementation cost.
A product team compares wireframe concepts for a new checkout flow against the existing design, scoring usability, conversion potential, and development effort.
A Pugh Matrix (also called Pugh Method, Concept Selection Matrix, or Decision Matrix) is a tool developed by Stuart Pugh for comparing design concepts or alternatives against a baseline. Instead of assigning numerical scores, you simply rate each option as better (+), worse (-), or the same (0) as the baseline for each criterion. This relative comparison approach is simpler and often more intuitive than weighted scoring methods.
Use the Pugh Matrix when you have a clear reference point (like your current solution) and want quick, relative comparisons. It's ideal for early-stage concept screening when you don't have detailed data for precise scoring. Use a Weighted Decision Matrix when you need more granular differentiation, have specific data to score against, or when criteria have significantly different importance levels.
Sum up the positives and negatives for each option. The option with the highest net score (positives minus negatives) is generally the best alternative. Also look at the pattern of scores: an option with mostly '+' marks on your most important criteria might be preferable to one with a higher total but weaknesses in critical areas.
Absolutely. The Pugh Matrix was originally developed for engineering design and is widely used in product development. Design teams use it to compare concept sketches, evaluate material choices, and select between different technical approaches. It's particularly effective when you need to involve multiple team members in the evaluation process.
Choose your baseline carefully - it anchors all comparisons. Include diverse criteria covering different aspects (cost, performance, feasibility, risk). Involve domain experts in the scoring. Consider running multiple rounds with different baselines to test sensitivity. If results are too close, you may need to add weighted scoring or more discriminating criteria.
