Risk Factor Assessment of Software Usability Using Fuzzy-Analytic Hierarchy Process Method

Abstract

Software adds significant value to a wide range of products and services. Thus, in the process of software development, maintaining the quality of the software is an important aspect that the developer must do. In several software quality models, usability is stated as one of significant factor that gives impact to software performance. The existence of problems in usability lead to less useful of the software. This research was conducted to assess software usability risk factors which derived from the attributes and sub-attributes of usability, that affecting the quality of the software negatively. The importance of risk factors assessed by using fuzzy-Analytic Hierarchy Process. This risk assessment on software usability made it possible to process the evaluation of the respondents defined by linguistic format, in which information can be processed from insufficient data, subjective, inaccurate or vague. As result, this assessment showed dominant factors which were considered as the source of the usability software risk.
