Measurement of Object Oriented Software Usability Using Fuzzy AHP
Software usability became an important quality factor in recent years due to the increasing demand of interactive software systems. Now mostly systems are developing using object-oriented methodology. The object-oriented methodology reduces design complexity, so enhances usability. Also object-oriented approach improves the usability of software system when software engineering process combined with usability engineering. This paper proposes an extended ISO-9241 usability model. Since fuzzy modeling approach deals with uncertainty and impreciseness involved in usability and its sub-factors, this paper investigate the application of fuzzy AHP technique to ISO-9241 model and the proposed enhanced ISO-9241 model. The result shows better usability of proposed model in comparison of existing model.
