Shainin vs. Fisher vs. Taguchi DOE

[Andrews]

Where can I learn more about Shainin DOE?

Has it really been able to reduce your ppm level?

DOE itself will not reduce ppm levels. DOE is a technique, which, if used properly, can astablish cause and effect relationships. It gives you a better insight of your process. ppm levels can reduce as an effect of actions you take on your process, based on the better knowledge you have acquired about it.
This is not true for Shainin DOE alone, but also for the Fisher and Taguchi variants of DOE.

where can i get this book? could you have soft documents about DOE?
IF SO,WOULD YOU LIKE TO SHARE WITH ME?

Rick,

I'm afraid I don't have the book in soft copy format. I think you'll have to check on line booksellers like Amazon.

For some good online articles on DOE, please refer:

Rick -

Shainin's techniques are copyrighted, trademarked, etc. Class participants are required to sign a contract that they will not teach the material to others. The only way to learn about Shainin is to go to his classes in Detroit. www.shainin.com

His approach is very efficient. His class is very expensive. Bottom line - I recommend the class. If I can be of further assistance, shoot me an email.

Best of luck,

Can anyone summarize the major differences between the Fisher, Taguchi and Shainin variants of DOE?

[sulkinsf]

I cannot answer the question in a single post, but perhaps I can start.

Borrowing from Tom Scripps class, "DOE" held at the ASQ Quality Institute on Six Sigma, and my attendance in Shainin's Statistical Engineering class...

The purpose of conducting experiments to gain knowledge. I would characterize the differences in Fisher, Taguchi, Shainin as the depth of this knowledge gained by each design. Typically, you would start with a shallow, screening design and progress to focused, deep designs.

Fisher is the father of DOE. His work is referred to as Western or Classical school of DOE. The classical school first asserted Full Factorial designs (all variables and interactions are studied).

Taguchi works off the principle that most variation is attributed to only a few input variables. Study of all variables is not necessary. The Taguchi school asserts Fractional Factorial designs (study only a few variables).

Shainin's work is proprietary. I signed away my first born that I would not reveal his protected work. However, my opinion is that this is the most simplistic of the three. The designs are much smaller and quicker, but you give up the thoroughness of Fisher designs.

Each has strengths and limitations. Each has its own purpose (confirmatory, exploratory). It is very likely that, in the process of understanding your process, you will use more than one design.
