Improving sustainability performance metrics using usability framework and WCAG 2.0 standard

Sustainability has been included in the Sustainable Development Goals by the United Nations. Software sustainability shows the effect of its development and usage on the aspect of economy, social, and society. One of the methods to measure software sustainability is by using the Sustainability Performance Metric. This study conducted a sustainability evaluation of the Internship Management Information System (SIM-PKN) using the metric with a modification in the usability and accessibility measurement. The framework’s General Graphical and Structural Evaluation are used for evaluating the usability aspect, while the accessibility evaluation is based on the WCAG 2.0 standard. Although the assessment has proven that SIM-PKN has fulfilled the elements of portability, support, performance, dependability, predictability, and efficiency, some problems with usability and accessibility aspects are identified.
