1	Evaluation of User Interface to Improve Documentation within the Elderly Care System Lindqvist, Sheila January 2019 (has links) The usability of a software product is dependent on the end-user and the context of use. Having a user-friendly user interface that is appealing and easy to learn and use is essential for improved human productivity. However, this is not always the case. For instance, the computer-based documentation system Siebel used within the elderly care system; is perceived by most nursing assistants as complicated. The goal here is to evaluate the usability of the system's user interface, applying the usability metrics stated in the ISO/IEC-9126-1 standards to quantify the effectiveness, efficiency, and user satisfaction of Siebel’s documentation system. A prototype user interface was developed for comparison with the current system. Likert-scale five-point scale; System Usability Scale (SUS) questionnaires were used to measure User satisfaction. The results mirrored that the participants preferred the newly developed prototype user interface to the existing user interface User Interface Siebel Documentation Evaluation ISO/IEC Standards Lo-fi prototype Likert-scale Cronbach’s Alpha Scenario Storyboard Persona Computer Sciences Datavetenskap (datalogi)
