ABSTRACT


The lack of attention to the correlation between the attributes of usability requirements leads to several problems with software development. This paper presents a novel framework that focuses on the mapping of usability requirements attributes to the linguistic assessment from the users using fuzzy logic. Our proposed framework prioritizes conflicting usability requirements attributes. For implementation, we have used MATLAB Fuzzy Logic Tool box. This proposed framework is aimed at helping the requirement analyst in taking better decisions by automating the whole process of identifying and resolving usability requirements conflicts. The major task in the proposed system involves determining the numerical value for each attribute considering their respective importance in different quantitative and qualitative evaluation standards. On the basis of numerical value, conflicts and their respective severities are identified.

VI. CONCLUSION


Literature review shows that most of the work being carried out in domain of usability engineering lacks any systematic usability assessment technique that focuses on the assessment of the conflicts among usability attributes. It costs a lot of time, rational burden, may be the wrong decision and there is no logical method to make decisions on it. Prioritization of the conflicts among usability attributes is undeniably vital for the development of more usable software systems, we have scrutinized the relationship between usability attributes. Use of the fuzzy logic approach to quantify the conflicts among usability attributes have two advantages: firstly as the data are imprecise, so fuzzy inference is capable of computing such type of data to determine the accurate values. Secondly, fuzzy inference can handle dependencies among variable in the system by decoupling dependable variables. Hence utilization of fuzzy logic helps the ranking procedure by making it trustworthy and accurate. In future center of attention will be on: (a) strengthening of the proposed approach by integrating the entire sub sub-factors of usability attributes in a more comprehensive way. (b) to assist the framework deployment, it is also planned to develop a tool that can facilitate requirement engineers and software developers in managing conflicts among usability requirements automatically.
