Many Green Belts and Black Belts go through extensive Minitab training. The program also includes detailed walk-through tutorials to help new users learn about the interface and features.
While some aspects of the interface take some getting used to, overall, it is straightforward. One of the main challenges in the area of usability is the ability users have to run any number of tests or analysis without necessarily confirming that they are applicable or knowing how to properly interpret them.
The same issue holds for the many graphical display options, which need to be understood in order to be interpreted correctly. And users need to be aware of the difference between a null value, a value of zero, and a missing value in data sets, or results may be incorrect.
The worksheet component does have one feature of which users should be aware, as it differs from the functionality within Excel and other spreadsheet programs to which users are likely accustomed. In Excel, if a user hits the delete key while one cell is selected, the contents of the cell are deleted, and the cell remains but is empty. In Mintab, however, if a user presses the delete key with a cell selected, the whole cell is deleted and the other cells in that column are moved up. Using the backspace key will duplicate the functionality that occurs with the delete key in Excel.
