A three-stage model of requirements elicitation for Web-based information systems

摘要

Although requirement elicitation is generally acknowledged to be very important in traditional information systems development (ISD), it does not get enough attention in most Web-based information systems development (WISD). This paper highlighted the difference between ISD and WISD, and proposed a three-stage model of user requirements elicitation for Web-based information systems. This model divides the requirements definition into three stages: initial analysis, key user requirements elicitation and regular user responses. Most current WIS design methodologies consider only initial analysis, and neglect actual users' requirements. Key user input is emphasized in this model, and social network analysis is proposed as a tool for identifying key users. Requirements analysis for WISD is no longer considered a one-stop step, but is better regarded as a continuous evolving process. Finally, managerial implications are also provided in this paper.
