Training Alert: Take advantage of free DOE e-learning from the online Stat-Ease Academy
All Stat-Ease e-learning classes now come free of charge, with access to the materials for 60 days. Those of you who need ongoing education to maintain their professional credentials; for example, certified quality engineer (CQE), can earn valuable hours of certification (PDF/CEU) by successfully completing any of our Stat-Ease Academy classes.
FAQ: The new multiple-window views in version 11 of Design-Expert (DX11) are great for seeing results at a glance, but for presentation purposes can they simply be reconfigured to a single pane?
Original question from a Statistician:
“I prefer the single-pane view as my default for ANOVA and diagnostics when teaching DOE classes with DX11. I have not been able to find a way to make it a default. I thought in an earlier version it stayed at whatever you used the last time. I could be mistaken, but nonetheless it doesn’t seem to do that now. We are using 11.0.6.”

Answer from Stat-Ease Consultant Martin Bezener:
“Once you change the pane configuration, it should remain that way in the file, even after closing and reloading.”

Info alert: Success stories for DOE done with Design-Expert: Halving development time of a cutting fluid and making a breakthrough for preserving maltodextrin samples
As reported recently by Chemical Processing, Houghton International experiments put the multifactor testing efficiency of DOE to good use for quickly developing a versatile cutting fluid. See details in this post of the published article.

The August/September issue of Laboratory Focus features a factorial experiment that quickly uncovered the cause for sample-preservation problems. See how it was done here.
Workshop alert: New class tailored to development of medical devices
You can do no better for quickly advancing your DOE skills than attending a Stat-Ease workshop. In these computer-intensive classes, our expert instructors provide you with a lively and extremely informative series of lectures interspersed by valuable hands-on exercises with one-on-one coaching. Enroll at least 6 weeks prior to the date so your place can be assured—plus get a 10% “early-bird” discount.
