DESIGN OF EXPERIMENTS

Hadamard Matrices (www.research.att.com/~njas/hadamard/index.html)
For the mathematically adventurous, the library of Hadamard matrices at N.J.A. Sloane’s site is a great resource when considering this Plackett-Burnman feature.

Math Options Inc. (www.mathoptions.com)
The Math Options home page caught my attention for three reasons: First there is a “Don’t like math?” feature--uncommon for a company dealing with DOE. Second, Math Option offers a free experiment--send them data and they will run an experiment for you. Finally, it uses two of my favorite words: free download.

MathSoft in Education (www.mathsoft.com/education)
If you are involved in either secondary or post-secondary statistics education, this site might be of interest to you as it offers a specific program and a series of products for educators. Use this site to download a free read-only version of Mathcad 8 Explorer, browse mathematical documents and access a Web forum for Mathcad users.

Nonexperimenter Tries Design of Experiments Software (www.statease.com/PCI1198.html)
In his review of a StatEase product, Rich Burnham--an individual with only a “fragmentary DOE background”--explains what he learned about the method. “I was in awe of the power of DOE,” Burnham writes. “It’s an amazing, systematic approach to experimentation that considers all factors simultaneously. It provides information about interactions among factors and the way a total system works, not just a few factors.”

Pick a Design, Any Design (www.qualityamerica.com/knowledgecente/articles/pickadesign.htm)
Authors C.J. Keller and Richard Scranton write that most people have heard of DOE, but find “the insides of [their] eyelids more pleasant to look at than the books devoted to the topic.” The authors describe and compare different DOE designs and the impact these designs have on the number of runs and factor ranges.

Process and Product Improvement with DOE
(http://www.qualityi2.com/doe.htm)
The home page of Qi², a consulting and training firm, offers a course on DOE with an emphasis on Taguchi. In outlining the course, this site briefly describes DOE, lists its benefits and highlights Taguchi’s methods.

Teaching Design of Experiments Using a Job Aid and Minitab (www.minitab.com/resources/whitepapers/crowder.htm)
This is a good example of the kind of articles commercial sites have begun adding for value added purposes. The article presented by Minitab offers a detailed case study on creating a DOE curriculum and teaching a course on the subject.

Twenty Key Elements of a Product Realization Process (www.prosci.com/prp1.htm)
ProSci’s BRP (Business Process Reengineering) Online Learning Center home page is not specifically a DOE site. It does, however, list 20 key elements of a sound product realization process, many of which address tools of DOE. The site also includes a list of the 56 best practices of the product realization process including testing skills and design and manufacturing analysis.
