Here's another set of frequently asked questions (FAQs) about doing design of experiments (DOE), plus alerts to timely information and free software updates. If you missed the previous DOE FAQ Alert, please click on the links at the bottom of this page. If you have a question that needs answering, click the Search tab and enter the key words. This finds not only answers from previous Alerts, but also other documents posted to the Stat-Ease web site.

Here's an appetizer to get this Alert off to a
On a lighter note (literally!), my son Hank (a programmer for Stat-Ease) passed along this heads-up (literally!) on colored bubbles invented by a fellow resident of our Twin Cities (Saint Paul and Minneapolis) in Minnesota: http://tinyurl.com/ca9ga (shortcut* to a page at http://www.popsci.com). Click the link to "Ascadia Zubbles" for more pictures and details of these amazing-looking "zubbles"touted at http://www.zubbles.com/. There you will find a two-minute video to brighten your dreary day. Why didn't I think of this? See my mixture design on a home recipe for do-it-yourself bubbles (not colored, unfortunately), at http://www.statease.com/news/news9709.pdf.

Here's what I cover in the body text of this DOE FAQ Alert (topics
that delve into statistical detail are designated "Expert"):
1. Newsletter alert: December issue of the Stat-Teaser features writeup on ruggedness testing, plus details on V7 release of Design-Expert® software, including an order form
Many of you will soon receive a printed copy of the latest Stat-Teaser, but others, by choice or because you reside outside of North America, will get your only view of the December issue at http://www.statease.com/news/news0512.pdf.
The feature article, "Struggle for Power vs. Resolution vs. Simplicity in an ASTM Standard," tells how I helped upgrade the strategy of experimentation specified in E1169 for Ruggedness Testing. This may be of particular interest to those in regulated industries who must be concerned with validation of their products and processes.
Also in this issue of the Stat-Teaser you will find details on the new release of Design-Expert software, along with a handy order form that can be faxed in to purchase new licenses or economical upgrades.
2. Software alert: Design-Ease®
version 7 now in beta releaseNeeded: A few good testers
Our programmers turned off the high-end response surface methods and mixture design features in Design-Expert version 7 (DX7) software to create a simpler and easier-to-use Design-Ease (DE7). This program finds favor with those for whom experimentation is not second nature, for example those tasked with Six Sigma process improvements in non-manufacturing areas such as marketing or administrative transactions.
In any case, if any of you readers can spare some time to take a look at DE7-beta, send me an e-mail requesting the link for the download and associated tutorials. Mailto:Mark@StatEase.com
3. Info alert: A "Da Vinci approach" to sensory development
Dr. Mathias Sucan, an independent consultant, attended our recent presentation of Mixture Design for Optimal Formulations. He provided the following 'heads-up': "As a user, I have been a big promoter of Design-Expert everywhere I have worked, where I successfully used it to optimize numerous formulas that sold for several millions of dollars. I learned to use the software as a tool, and to call on it at the right time during the course of product development. I integrated my experience with your software in a recent article on flavor development entitled 'The da Vinci Approach' in the May 2005 issue of Perfumer & Flavorist."

4. Events alert: Design for Six Sigma (DFSS) conference
We will attend and display our software at the Design for Six
Sigma conference, January 16-18, 2006, in Memphis, Tennessee. Among
the speakers are several (probably more that I missed or don't know
of) clients of Stat-Ease software and training resources:
