Since smartphones have become the most prevalent communication tool in the world, a wide variety of low-end to high-end smartphone products are currently available on the market. Choosing a suitable product becomes a challenge due to the problem of feature fatigue. This study developed a smartphone selection procedure for prospective users by incorporating ELECTRE-III method with Kano two-dimensional quality model. An empirical example of 15 smartphones from three different categories, namely, flagship, screen size and price, demonstrated that the credibility matrix of the revised ELECTRE-III had fewer extreme values (0 and 1) than its original counterpart. It was able to clearly distinguish the relative satisfaction of each option in the respective group, particularly for the tied products which could not be discerned by the original ELECTRE-III.
