Design of Experiments (DOE) Made Easy


Design Expert v13

Make breakthrough improvements to your product and process with Design-Expert® software from Stat-Ease. 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® helps you

ds experimentDesign 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 would even imagine. Check it out!

ds analyseAnalyze 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. Do not take our word for it, test it out with one or more of the data sets that come with the software.

ds visualizeVisualize 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.



Designed experiments require some up-front planning to be successful. Following questions needs to be answered:

1. “What is the objective?
2. Identify the responses that need to be measured.
3. Which factor effects should be examined?
4. How many runs does the budget allow?

Do not get too worried. Take the process question by question.

• Use the Design Wizard to walk through the above questions in more detail.
• Build a New Design to skip the wizard and build a design directly.

New Release: Version 13!

Version 13 of Design-Expert® includes many new additions to its design, analysis, and visualization components. All done while keeping our intuitive and easy-to-use interface intact.

augementationNew in v13: Design Space Augmentation Wizard
Expand, contract, or shift your design space to hone in on an optimal area. DX13's wizard makes this easy for both process and mixture designs. Re-use existing data (or remove some) and make the most out of your experiment!


PoissonNew in v13: Poisson Regression
Use Poisson regression to fit more precise models when the response is count data (discrete, non-negative), such as the number of defects per unit or the number of occurrences per time period.

Multiple analysisNew in v13: Multiple Analyses
Easily model any response in various ways to easily compare them. Simply press the plus (+) button on the Analysis branch and try different model reduction methods or transformations. Choose the best analysis for achieving optimization goals.
