Make breakthrough improvements to a product or a process with Design-Expert® software. You can not only screen for vital factors, but also locate ideal process settings for top performance and discover optimal product formulations.


Design-Expert® provides many powerful statistical tools, such as:

  • Two-level factorial screening designs: Identify the vital factors that affect your process or product.
  • Response surface methods (RSM): Find the optimal process settings to achieve peak performance.
  • Handle hard-to-change factors via split plot design and analysis
  • Mixture design techniques: Discover the ideal recipe for your product formulation.
  • Combinations of process factors, mixture components, and categorical factors: Mix your cake (with different ingredients) and bake it too!
  • Screen and optimize in one go using Definitive Screening Designs

Use rotatable 3D plots to view response surfaces from all angles. Use your mouse to set flags and explore the contours on interactive 2D graphs. The numerical optimization function finds maximum desirability for dozens of responses simultaneously!

Improvements made to Design Expert® over the years have been useful and worth the upgrade if you already own a license. Version 11 brought ever more design options for split-plot and overall an updated interface. We particularly like the way the analysis output is done, where the ANOVA results and Diagnostics plots can be displayed in upto 4 panels of the main window, thus making better use of today's high-res screens.
