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.
