Abstract
There are a lot of academic researches focusing on the aspect of analyzing the usability of software; yet, curiously, few on the practical analytical mode. This research, therefore, from the aspect of applied system engineering, takes the whole evaluation procedure as a systematic one and further establishes a systematic software on analyzing usability of software.The aim of this research is for the software programmer to realize there are various techniques for analyzing utilities on different stages of programming. By a sequential analysis, improvement, and maintenance, the software can be programmed to be more reliable as expected and, further, to be more learnable and easier of use.To testify the reliability of this research, the methodology being adopted is to run a program on analyzing the usability of the software, Enterprise Resource Planning in the elected company. On the process of analyzing, the standards of the interfaces and the questionnaires can be organized and the utilities can be testified.
