A Proposed Metrics Based on Sustainable Development Goals (SDGs) for Public Self-Service Machines

With the growing environmental issues, the World Commission on Environment and Development (WCED) has developed a strategy for sustainable development that will enable the present generation to meet its needs for development without harming the environment for future generations. By introducing a 24-h self-service via Public Self-Service Machines, several issues can be alleviated, such as the congestion in the traditional service environment, to support specific services outside of the traditional office hours, and to allow citizens to feel that the government is committed to providing convenience and mindful public services. However, few existing studies have examined sustainability as a fundamental attribute of these Public Self-Service Machines. This lack of focus would result in Public Self-Service Machines not being sustainable in the long run. Therefore, further research on how to design and measure sustainable development attributes for Public Self-Service Machines is necessary to address this issue effectively. In this paper, the sustainable development attributes of Public Self-Service Machines based on the 17 Sustainable Development Goals (SDGs) are firstly presented. Then, a questionnaire survey was conducted to collect and analyze the views of industry experts to propose 13 metrics to measure the sustainable development attributes of Public Self-Service Machines.
