Usability: A Concept Analysis.
- Authors
Shultz, Sarah; Hand, Mikel W.
- Abstract
Many definitions of usability exist, but most of these are brief and imprecise. Usability describes systems and technologies that are self-explanatory to untrained users. Citations from medicine, nursing, allied health, and modern art and architecture were obtained. Key search terms used were usability, informatics, modern art and usability, structural design and usability, and electronic medical record and usability. Defining attributes were learnability, efficiency, and user satisfaction. Antecedents included human user, technology, information, and task. Consequences included user's perception of high degree of usefulness, efficiency, safety, and user's satisfaction with using technology. Empirical referents of usability were exemplified by measures of ability to use technology in a satisfying, meaningful, and productive way to meet the desired outcomes. Usability is theoretically defined as the degree to which the user perceives learnability, efficiency, and satisfaction when using a healthcare information technology system.
