I have used this software for two years and It has helped me a lot through designing experiments and also in creating models.

The features are user-friendly. You can easily prepare the spreadsheet for your experiments. The first month is free so you can get an experience of how it works before purchasing. I think the student license version is reasonably priced.

The statistical analysis section is a little complex especially for those who are not expert in statistics.

Design Expert is my everyday go-to program for designing experiments. Whether it's a screening experiment, factorial, response surface or mixture experiment, I use this software for the design and then the subsequent analysis. In that past 11+ years, I don't recall encountering any design need that Design Expert could not handle.

Design Expert offers the user a lot of help for designing and experiment and for analyzing the results. To set up a design, you can use their wizard, which uses a question and answer approach. If you are more of a do-it-yourself type, they still offer guided screens for whatever type of design you think you want to use.

The graphics could be better. While it's easy to export the graphs to Word or PowerPoint, the graphs themselves look a bit old-school and the ability to edit them is rather limited.

I have used Design Expert since 1989 (version 1.1) so I have 30 years of working with Stat Ease on the development of the software. I have found the people a Stat Ease to be easy to work with and they are very receptive to suggestions and comments. I personally know several people who work there and have visited them a few times. I highly recommend this software for anyone interested in designing and analyzing their own DOEs or supporting others.

Design Expert can handle virtually any type of experimental design that you may need in a wide variety of situations. Certainly, the broad array of factorial, response surface and Taguchi designs can help anyone interested in applying DOE to a process. For those interested in formulation development, there is a nice selection of mixture and mixture/process designs to choose from. Design Expert is particularly help in its easy to navigate menus, great graphics, and their tutorials are very well-done and are highly recommended!

There are a few designs which Design Expert doesn't have, such as space-filling designs for computer experiments. I rarely have the need for such designs so this is not a serious limitation of Design Expert.
