Abstract [en]

Medius is a software company which provides IT-solutions that streamlines and automates business processes. The purpose with this thesis was to investigate the possibility to integrate usability evaluation in the development process of Medius software MediusFlow. How such integration would be done, and which usability evaluation methods could be used.

To be able to provide a suggestion, a prestudy was conducted, this in order to get a good overview of Medius as a company as well as the development process of MediusFlow. With the prestudy as a basis, the main study was conducted, and four different usability evaluation methods were chosen. In this study, the four chosen methods were Cognitive Walkthrough, Coaching Method, Consistency Inspection and Question-Asking protocol. These usability evaluation methods were carried out, evaluated and analyzed. 

Based on the studies and the literature, a suggestion regarding integration of usability evaluations was made. 

The result from this case study was presented as a process chart, where the different phases in Medius software development process are matched together with suiting usability evaluation methods. The relevant phases and their suggested methods:

Preparation phase - Cognitive Walkthrough and Coaching Method in combination with Thinking-Aloud and Interviews

Hardening phase - Coaching Method in combination with Thinking-Aloud and Interviews, as well as Consistency Inspection

Maintenance - Field observation

This result is a part of the overall work towards a more user-centered design of the software.
