Abstract

With the rise of the digital age, people are increasingly exposed to the visual environment such as online websites that commonly contain usability issues. This study established a framework for improving the usability of an online birth certificate application website as measured through the Single Usability Metric (SUM), with completion rate, error rate, satisfaction, and task times as usability metrics. This is done by incorporating the concepts and guidelines provided by the design factors such as page layout, user's workload, and lists. Usability testing was conducted to gather quantitative information for measuring the usability metrics, which were standardized to obtain the SUM of the current design. The design factors were then analyzed and improvements were applied to develop a new design. A follow-up usability testing for the new design was conducted and results showed that the SUM increased from 1-sigma to 3-sigma level. The framework consisting of the design factors on web design development is deemed effective in improving the usability of a website. © IEOM Society International.
