This document presents the thesis project “Usability Studies of Wireless Systems, Design of the MUST – Method for Usability Studies and Tests” that was part of the requirements for the degree of Master of Science in Electrical Engineering at the Royal Institute of Technology. The work was carried out at Ericsson WLAN Systems. They develop mobile enablers and had realized the importance of adding input, from the actual users of the systems, into the developing process. The problem was that Ericsson WLAN Systems did not have any kind of strategy for performing usability studies or user tests. The need for a method for usability studies initiated this thesis project.
The method is called MUST (Method for Usability Studies and Tests) and directs itself towards a project leader and/or usability engineer. It interprets the indistinct and abstract declarations of usability into concrete tools for usability engineering. The method is applied alongside the ordinary development process to enable early and constant focus on usability and to structure the usability engineering. The MUST is divided into five different phases that form a lifecycle, describing the workflow when conducting usability engineering: Know the User, Setting Goals, Prototyping, Testing and User Feedback. Every phase within the MUST lifecycle has a specified goal to be achieved and methods to be used to achieve it. MUST also helps connecting the information flow from product management through software design to support.
MUST has been tested in parts within this thesis project. Ericsson’s High Security System was put through a Thinking Aloud Test and new and interesting data was gathered through this test, revealing what the users really thought about the product as well as how they actually interacted with it. The results became valuable input to the up-grades of the High Security System.
