Design of Experiments (DOE) Made Easy

Make breakthrough improvements to your product and process with Design-Expert software. Screen for vital factors and components, characterize interactions and, ultimately, achieve optimal process settings and product recipes. Set flags and explore contours on interactive 2D graphs; then visualize the response surface from all angles with rotatable 3D plots. Finally, maximize desirability for all your responses simultaneously and overlay them to see the “sweet spot” meeting all specifications. Design-Expert makes it incredibly easy to apply powerful multifactor testing tools. Give it a try to see what it can do for accelerating your research and making it a huge success.

Design Your Experiment

Design-Expert provides powerful tools to lay out an ideal experiment on your process, mixture or combination of factors and components. When in doubt, build it stout via in-line power calculations and the ability to add blocks and center points. Design-Expert’s design wizards and intuitive layouts such as the stoplight configuration for two-level factorials make it all far easier than you’d even imagine. Check it out!

Analyze Your Data

Design-Expert makes it easy to see what, if anything, emerges as statistically significant and how to model the results most precisely. It provides the confidence you need to present and, perhaps, publish your findings. Don’t take our word for it, test it out with one or more of the data sets that come with the software.

Visualize Your Results

Design-Expert offers a wide selection of graphs that help you identify standout effects and visualize your results. Its outputs create a strong impression when you communicate your findings to supervisors and peers. Download the free trial today, skim through the response surface tutorial provided under ‘Help’, and see for yourself.

New in 22.0: Analysis Summary

The new Analysis Summary expands the previous Coefficients Table with more model-fit statistics. Easily view p-values, R-squares, model equations and more, across all responses.

Available Now: Hosted Network Licensing

A new licensing option is available to host a network license at This allows you to run the software on multiple devices without requiring an on-premises license server, thus reducing costs for DIY software deployment and management.

New in 22.0: Custom Graphs

The Graph Columns node has been upgraded to Custom Graphs. You can now plot analysis data like predicted values and residuals –plus distinguish points by size and symbol.
