Iterative usability testing: ensuring a usable clinical workstation.

Abstract

Once the users' needs are determined, how does one ensure that the resulting software meets the users' needs? This paper describes our application of a process, usability testing, that is used to measure the usability of systems as well as guide modifications to address usability problems. Usability testing is not a method to elicit opinions about software, but rather a method to determine scientifically a product's level of usability. Our application of usability testing is designed to determine the current usability level of a workstation designed for the clinician's use, determine specific problems with the Clinical Workstation's usability, and then evaluate the effectiveness of changes that address those problems.
