**DOE Integrated Methodology**

It is well known that today we have three options to use "DOE phylosophies":

Traditional DOE

Taguchi Methods

Shainin Techniques

And there are tremendous disscussions about which is best!

but what happen if we combine the best of them in an integrated methodology?

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, considering time, cost, efforts involved?

Ideas, suggestions, comments, are welcome!

thanks for your help!
