Week13 Pugh Decision
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.

Week12 Introduction to TRIZ
The last module is taught by Prof. Ang. (pic from left) He is very friendly, helpful and always put on a smilling face. In his class, he always commented positively, this make me feel comfortable attending his lesson. I believe there is more I can understand and learn from him in personal character building.
So much on Prof. Ang. Let talk on TRIZ.
What is TRIZ?
TRIZ is a problem solving method based on logic and data, not intuition, which accelerates the project team's ability to solve these problems creatively. TRIZ also provides repeatability, predictability, and reliability due to its structure and algorithmic approach. Some of the analytic methods are:
- The Ideal Final Result and Ideality
- Functional Modeling, Analysis and Trimming
- Locating the Zones of Conflict
Some are more prescriptive such as:
- The 40 Inventive principles of Problem Solving
- The separation Principles
- Laws of Technical Evolution and Technology Forecasting
- 76 Standard Solutions
Those who are interested to know in TRIZ in depth and practice 40 principles of problem Solving, visit this website http://www.triz-journal.com/whatistriz.htm. This website also show some example on using TRIZ to come out with possible solutions on a particular problem.
