Iterative usability testing: ensuring a usable clinical workstation.

Author information

Section of Medical Informatics, Washington University School of Medicine, St. Louis, Missouri, USA.


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.
