Various methods were used to capture user requirements. They include the use of models, prototypes, cases among other techniques. The traditional way of doing requirements analysis was not enough as the task of analysis was left to the developer, but the users will be the primary users. The research evaluates previous studies that have evaluated past requirements acquisition methodologies and techniques. A comprehensive summary of requirements analysis and knowledge acquisition is provided by (Byrd et al. 1992). There has been a step forward towards joint participation in the requirements elicitation process in information systems. User participation is encouraged and process automation is slowly adopted. Barriers to requirements elicitation include within-obstacles, between-obstacles, between-obstacles (Byrd, Cossick, & Zmud, 1992). Internal obstacles occur due to individual limitations of both the user and the developer in processing information and solving problems. The middle hurdle occurs due to the different level of understanding between developers and users. Inadequate knowledge of the problem domain, lack of technical expertise on the part of the user, and lack of a common language (Davis 1982; evaluatek and Fryback 1985) are some of the major obstacles. Obstacles occur due to different needs of different users, so requirements analysis is necessary to evaluate multiple needs, and a negotiation mechanism to agree on needs is also of great importance. (Fazlollahi and Tanniru (1991) describe the contingency model. The contingency model is one of the traditional models used. The model involved a three-step process that involved determining the level of uncertainty that exists in a system, then… a half of paper... (ed.)
