Pugh Decision analysis matrix is a tool in the Six Sigma toolbox. The optimum use of the tool is for those situations where we have many alternative concepts to choose from, with each concept entailing multiple attributes (product / process considerations).
The process flow for tool use is:
- From Six Sigma, Define the problem.
- Define the cross-functional team that will work on the problem
- Define what we consider to be the “baseline”. e.g. a product or process that we have in place that is considered non-optimal.
- Define the requirements (CTQs ~“attributes”) and criteria that will be used in the analysis.
- Define the alternative concepts that will be included in the analysis.
- Define rating scale that will be used in the prioritization and trade-off attribute analysis.
- Define the scaling criteria that will be used in the concept analysis.
- Set up the Pugh Matrix.
- Analyze and rank each concepts benefit.
- Conduct “what-if” simulation studies and re-assess concepts benefit (optional).
- Select the concept(s) that detail the most benefit.
- Initiate development/optimization analysis activities on the concept chosen.
There is a website which you can learn the basic statistical tool, have tutorial and practice tests.
