Use of Classic Risk Analysis in Usability Engineering Work with Trams and Elderly
Paper i proceeding, 2007
In the work with usability for the traffic environment, safety aspects are crucial, especially for the elderly population. This paper presents the use of a classical risk analysis method, Fault Tree Analysis (FTA), when analysing usability aspects in two case studies regarding trams and elderly users. In these studies, the FTA-method was used as an analysis tool for empirical collected data from observations and interviews. The method worked well for formation of data as well as for showing connections and relations between data. To conclude, the use of a classical risk analysis method has shown to give adequate results to usability engineering design.
