A discussion is presented of why some expert systems that organizations have developed are not successful. The concept of design process plays a very significant role at the outset of the expert system development process. This concept has not been the subject of much debate and attention in expert systems development. From the author's point of view, one of the main issues is how the designer (knowledge engineer) thinks about the design process. In general, the designer's process is influenced by the knowledge engineer's conception. This paper endeavors to disclose some of the main factors related to the knowledge engineer's conception of the design process and an attempt is made to put forward a conceptual model of the expert system design process. This conceptual model is an initial step towards a successful implementation of expert system projects.
The technology of computer has been applied to the automation of office tasks and procedures. The technology of expert systems make available a new methodology for automating knowledge-oriented processes. The development of expert systems raises a number of issues for the organizations. This paper presents a descriptive model regarding some potential impacts of expert systems on the organizations. The article points out the need, when implementing expert systems, to take a broader perspective of their potential effects on the organization. Moreover, the article puts forward some suggestions for a successful introduction of expert systems technology. The paper also indicates some avenues for further research on this matter.
The concepts of an information system's roles and responsib ilities can play a significant role in the outset of the information systems dev elopment (ISD) process. This aspect has not been the subject of much debate and attention in ISD. In this paper an attempt is made to outline a conceptual model of information systems' roles and responsibilities. This conceptual model is an initial step towards exploration of the relationship between the concepts of in formation systems' roles and responsibilities.
