Design-Expert® software, version 6 (DX6) offers features youwon't find anywhere else in an incredibly easy-to-use format.

This powerful program is a must for anyone wanting toimprove a process or a product. With Design-Expertstatistical software you can screen for vital factors, locateideal process settings to achieve peak performance anddiscover your optimal product formulations.

Design-Expert offers an impressive array of design options.Version 6 provides more flexibility to handle categoricalfactors than ever before and allows them to be combinedwith mixture and/or process variables. After building yourdesign, generate worksheets with your experiments laidout for you in randomized run order. Add, delete orduplicate runs in any design with the handy design editor.

With annotated statistical analysis and an extensivecontext-sensitive help system, you can easily interpret theoutputs. Interactive 2-D graphics support use of yourmouse to drag contours or set flags that displaycoordinates and predicted responses. Rotatable 3-D plotsmake response visualization easy.

With the powerful optimization features in Design-Expert,you can maximize desirability for dozens of responsessimultaneously. There are also unique tools forgenerating and graphing propagation of error (POE), thusallowing you to achieve six-sigma objectives for reducingvariation. Maximize, minimize or hit targets with factorlevels set to give you robust results.

"DX6 is the easiest to use, most complete andaesthetically pleasing DOE program I have seen. Therobust capabilities are not available anywhere else.The combined process-mixture designs make DX6 thebenchmark for all other DOE programs."

Ken Chatto, Consultant, Experimental Strategies, Inc. (South Carolina)
