How does Pugh Matrix work?

The Pugh Matrix (PM) is a type of Matrix Diagram [1] that allows for the comparison of a number of design candidates leading ultimately to which best meets a set of criteria. It also permits a degree of qualitative optimisation of the alternative concepts through the generation of hybrid candidates.

What is Pugh Matrix analysis?

The Pugh Analysis Matrix is an analysis tool that results in an optimal concept. You refine a list of ideas by using a matrix-based process to weight and compare the conceptual designs. Similar to pro vs cons. Evaluate multiple options vs a baseline. Use a matrix to address multiple factors.

How do you do the Pugh evaluation matrix?

Here is a step by step guide to use the Pugh Matrix.

1. Step 1: List down the Criteria in a Vertical List.
2. Step 2: Select the Datum.
3. Step 3: List down the Alternative Solutions Horizontally.
4. Step 4: Marking the Pugh Matrix.
5. Step 5: Aggregating the Scores.

Who made the Pugh Matrix?

Stuart Pugh
Stuart Pugh developed an improvement method called Pugh’s Controlled Convergence. More commonly known as the Pugh Matrix, it formalizes the decision-making process to help you select one or more improvement opportunities to pursue in detail.

Where is Pugh Matrix used?

The Pugh Matrix was developed by British product designer and mechanical engineer, Stuart Pugh. It’s a numerical decision-making tool normally used within DFSS (aka DMADV) Six Sigma projects. Its purpose is to validate multiple concepts and come to an agreement for the final design selection to proceed forward.

What is the purpose of a Pugh chart?

The purpose of the Pugh chart is to get you to systematically think of the pros and cons of each design alternative relative to your design criteria. The Pugh chart to the right is a sample from a student design project.

What is a Pugh chart used for?

A Pugh chart is a simple design tool for comparing design ideas against your design criteria early in the design process. To draw a Pugh chart, list the design criteria in the left column. Weight each criterion according to how important it is (use any scale you like).

How do I make a Pugh chart?

To draw a Pugh chart, list the design criteria in the left column. Weight each criterion according to how important it is (use any scale you like). Then list the design alternatives across the first row. Choose one design alternative as a datum.

What is the Pugh method of design selection?

A Pugh matrix is a selection tool used to help choose between multiple concepts for a new process, product, or service. It was originally used to evaluate and select between several product or process designs, as ranked against customer criteria and the current baseline design.

How do you create an evaluation matrix?

There are seven steps to creating a decision matrix:

1. Identify your alternatives.
2. Identify important considerations.
3. Create your decision matrix.
4. Fill in your decision matrix.
5. Add weight.
6. Multiply the weighted score.
7. Calculate the total score.

How do you create a score matrix in Excel?

How to Use The Decision Matrix Template

1. Step 1: Copy the spreadsheet template.
2. Step 2: Describe the decision you’re considering.
3. Step 3: Enter the factors or values that are important to your decision.
4. Step 4: Rank those factors.
5. Step 5: List the options you’re considering.
6. Step 6: Score each option based on each factor.
