Usability testing of a website through different devices: a task-based approach in a public university setting in Bangladesh

Abstract

Purpose

This study aims to investigate the usability of a public university website for measuring its efficiency, users’ satisfaction or anxiety while searching for and retrieving information through different devices.

Design/methodology/approach

A task-based approach was adopted for the study. Twenty-eight participants were asked to complete 11 information-searching tasks on the website. The participants were divided into two groups. The tasks were carried out by members of each group, using desktop and mobile devices in a rotating fashion. Volunteers observed the participants' actions and recorded information regarding their productivity, time usage (using a timer), satisfaction or annoyance while performing each task. Finally, based on the use of the devices, a comparison was established between the participants' performance accuracy, efficiency and anxiety.

Findings

The study provides an overview of a task-based user experience carried out on the university website using a combination of qualitative and quantitative research methods. According to the results, participants' satisfaction levels were generally high, and their anxiety levels were low while completing the tasks on a mobile device. In comparison to the desktop, it took less time overall to complete all tasks. On the other hand, using a desktop computer (97.1%) resulted in better task completion success rates for participants than using a mobile device (85.7%).

Originality/value

No previous task-based evaluation study of this kind has been conducted to assess the usability of any university website in Bangladesh.
