I'm interested!
I'm interesting to know about Tashiro problem solving process.
I'm working with the next methodology for a year and performs fine, read on!
We have many options to solve a problem, for example:
Traditional DOE
Taguchi Methods
Shainin Techniques
And there are tremendous disscussions about which is best!
but when we combine the best of them in an integrated methodology we have a
good "problem solving methodology" don't you think?
For example:
1. Definition of the problem (Pareto Chart, Brainstorming, etc)
2. Use the quality loss function to determine the non-quality cost.
3. Apply Multi-vari Charts to define type of variation in the problem
4. Perform a Orthogonal Array to find the most important factors
5. With the 2 or 3 most important factors found, validate the solution using DOE Traditional
6. Then we use again Quality Loss function to measure the solution or improvement.
in other words...
1. Pareto Charts, Brainstorming, Ishikawa fishbone diagram
2. Taguchi. Quality Loss Function
3. Shainin. Multi-Vari Charts
4. Taguchi. Orthogonal Arrays
5. DOE 2 or 3 Full Factorial to Validate the solution
6. Taguchi. Quality Loss Function.
In your opinion this methodology will work?
which are the advantages or disadvantages in the methodology?
Ideas, suggestions, comments, are welcome!
thanks for your help!
