Empirical evaluation of information system development process from the aspect of end user satisfaction

Abstract

The result of the work in this paper is a devise of an evaluation model of the development of a user friendly information system for efficiency of serving customers. But the point of the research is to devise some different prototype method - modified state- transition model - that accomdates simple information evaluation model that stresses on user information satisfaction for reflecting end user requirements. And for this research it is tried to question as many employee - 40 employee - as possible in IBM Korea to write up questionnaire and prove that the modified evaluation model works in this paper. And the rsult is that the final system reflects user information satisfaction and the model for measuring information satisfaction works effectively. Three prototypes are developed according to modified statetransition model that lets make a final system through an interaction of two prototypes. Before developing final system, information system evaluation model that accomodates small modification to former research is used to test how much user satisfaction is and to improve system strengthening the factors for user information satisfaction. In making the first prototype, C language is used and for the second prototype, database package is used and Clipper program is suggested to accomodate each good points and to remedy each bad points. And it is proved that final system developed with Clipper can promote user information satisfaction by the evaluation model. This system is not a multi-user system but it can be a prototype itself for the large company-wide multi-user customer management information database system. This last system will take the form of deductive object-oriented database accommodating the principles of object-oriented programming and logic programming.
