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-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!
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.
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.
We continue to release features for Design-Expert, including many new additions to its design, analysis, and visualization components while keeping our intuitive and easy-to-use interface intact.

Use this new at-a-glance interface feature to easily compare values across analyses, such as Lack of Fit and curvature p-value. Available to all licensed users of both Design-Expert and Stat-Ease 360, this visualization tool helps you easily and intuitively find the "sweet spot" in your product or process.
Choose from nine vivid color gradients (including a linear map for colorblind visibility) that remove false anomalies and improve areas of low contrast. Pick the best one for your project to show off the highs, lows, and curvature in your model & optimization graphs.
Create and analyze experimental designs using combinations of process factors, mixture components, and categorical factors. Utilize our optimal design function to let the program help you determine the exact points to test so you get the most information for the least amount of work.
If you have a team that would like an introduction to design of experiments (DOE) and Design-Expert software, our experts will customize a 1-hour demonstration for you.
