| Abstract |
| A well-designed user interface in terms of its usability can greatly increase the efficiency of the entire system. This study considers usability principles that are appropriate for web-based system interface and applies them to each step in the development process. The purpose is to establish systematic and logical development process and seek ways to apply it to practical designing. To conduct the research, based on surveying of existing bibliographical materials, 5 usability principles suggest by Nielsen, eight usability principles based on heuristic approach and characteristics of system users were considered. This is followed by an analysis of distinctive features of web-based systems and interface designs, from which usability principles` application priority is derived and thus the development process is established. For each development stage, tasks to be performed are analyzed and usability principles are selectively applied. Finally, based on the result, a prototype for interface designs of enterprise ERP system is developed and case studies regarding its application are provided. It is expected that the result of this study will help develop user-friendly designs by being effectively applied to planning for the interface of web-based systems. |
