Enhancing Performance Aspect in Usability Guidelines for Mobile Web Application

Abstract

The rapid growth of technology has boosted the usage of mobile devices to access a web application. These devices have various specifications such as screen sizes and resolutions. Responsive Web Design (RWD) approach bridges the gap of these differences by adapting the flexibility concept in screen sizes and resolutions, thus ensuring better website usability. Poor performance in website usability resulting in declination in number of users. Therefore several existing Usability Guidelines (UG) were invented mainly for a desktop-based website and unfortunately lesser studies have been carried out for a Mobile Web Application (MWA) especially the performance aspect of it. Henceforth, this paper focuses on enhancing the performance element of an existing UG by analysing, identifying, proposing, implementing, and measuring the new additional performance attributes in UG for MWA. We used First Contentful Paint (FCP), Speed Index (SI), Time to Interactive (TtI), First Meaningful Paint (FMP), First CPU Idle (FCI) and Estimated Input Latency (EIL) to measure the performances of two case studies and the result shows better score at 90-100 (fast-GREEN) with the proposed performance attributes compared to another website without it which averages at 50-S9 (average-ORANGE) range.
