A Study on Usability Requirement for Redesigning Student Information System

In web-based student information system development, usability requirements are the most important of non-functional requirements since they determine the acceptability of systems. Nevertheless, usability requirements are usually unconsidered in early stage of system development. Mostly the developers consider the functional requirement with expected to develop system with high function and technology. But high function without usability is not the main of the aims of system development. This paper aims to propose a requirement to assist and support the development process of student information system. This study conducts in-depth interview method to capture usability requirement which involves administrator, programmer, lecturer, and students. By using several task to guide user operate the system, some issues is discovered. Based on study, the result discovers that interactive design, task completion efficiency and interactivity is impact to usable system. It means the study need investigate which elements that influcence task completion efficiency and interactivity.
