Investments have been drastically increasing on mobile phone applications based on the increase in mobile internet usage. The fact that these investments should be utilized by many users has become an important agenda of business plans for many brands. It’s obvious that the differentiate value proposals of the applications are no longer just a function or a new idea, but the usability of the whole system is become more and more critical. For this purpose, published academic studies about the usability of mobile applications in the literature have been examined. From this research, it’s found out that researchers have been used various and differentiate criteria for the same objective. Thus, in this chapter, a new method has been proposed to decide which design parameters are affective for the related mobile application and to determine the importance degree of the design parameters to be taken within the scope of the usability evaluation of the applications. The methods including Kano Model, Quality Function Deployment (QFD), and Spherical Fuzzy Sets have been integrated into the proposed method. For this reason, the design requirements are categorized by using the Kano Model while QFD is used to integrate design requirements with design parameters to increase the usability dimension of the product. Spherical Fuzzy Sets were used to handle uncertainties and vagueness in the evaluation process of the approach.
