Use Robust Design Methodology.  Look at the follwing article.

I hope it helps

You can use rdExpert software to get test plans automatically.

The real advantage of Orthogonal Arrays appears when the factors have more than three levels.

Use rdExpert for Taguchi experiement.  It is very easy to use.
Manee

One good link for Taguchi mehtod is on this sight is http://www.isixsigma.com/library/content/c020311d.asp  A good software for Taguchi design is rdExpert from Phadke, where you can have three levels of inner and outer array and still save on experiemtation

You can see the article for test planning.
http://www.isixsigma.com/library/content/c030106a.asp  to establish some guidelines.

You could try rdExpert for multiple responses and analysis.
Manee

I am not sure you can do that in Minitab.  But you can use rdExpert software to DOE with multiple responses  and analyze the data for whole month. 
Manee

In Robust Design jargon, you exploit the non linearity.  Read Phadke’s book about quality
Manee

In 1997 RAMS conference, phadke explained that you don’t have to run 40,000 tests for a copy machine to guarantee that there will be no paper jam.  It had something to do with Robust Design.  They came up with less than 100 tests. You can contact him

It is not a free tool but you can get a demo copy from the dealer

You can use rdExpert to genrate an OA

With Taguchi’s Orthogonal array L8 can examine 4 factors with 2 levels in simple following way.

Many examples of applying design for six sigma in electronic design are available in ITT Industries Annual Taguchi Symposium

you can try the case study http://www.stsc.hill.af.mil/crosstalk/1997/10/planning.asp
by Phadke who is the pioneer to apply orthogonal arrays to software
Manee

This is a good example to use Taguchi’s paramter design. Water, Organic solvent and acid are used for control parameters and time, temprature are used as noise factors.  With proper design you can get results with few experiments.
Read any book on that subject to get the insights
