• A methodology for quantifying expert system usability is presented. Usability is considered from a designer's perspective: the designer must ultimately address any design Issues that may affect usability. A linear multivariate function for measuring usability is described. The function's independent variables represent user perceptions and performance. In an example a function of this form is developed and used to assign a usability score to a given expert system. The usefulness of the usability function as a design tool is also investigated.
