Automatically: QT4 can design simple of mixed level experiments when you only describe the factors and levels.

Manually: QT4 allows you to select the array and assign factors to the columns as you want. Unused columns and Triangular Table information is made readily available on demand.

How does Qualitek-4 Design Experiments? QT4 always starts with PISTON experiment (screen

Use Automatic Design When Unsure of Rules

All You Need is to Enter Numbers of Factors (Three 2-level & One 3-level)
