System development has been an innovational trend in the field of Information systems in both past and present time; and users of the system is one of the key success in the development life cycle of human and computer based systems. Information system is one of the most emerging technologies in developing countries; Nigeria as a case and the development of these IS is deployed in both private and public sectors of the economy for organizational data management. Due to some characteristics of developing countries such as poor communication facilities, unequal distribution of wealth, large population and so many others, many of these information system development has been carried out for the provision of services to both public and private organizations. But on the other hand, such projects have failed in one way or the other due to poor end user involvement in or during the development process. For this research, the involvement of users in developing country and more appropriate concepts which developers/designer could possibly use to involve users for a successful system were studied. The approach to this investigation was with the use of questionnaire which was distributed to the users of two different systems which were developed using different concepts of user involvement (Scenario-based user involvement technique and Interview-based user involvement technique). Statistical Package for Social Sciences (SPSS), was used for this quantitative analysis and the Independent t-test analysis was done to prove the significance between these systems. The findings from this study shows that in the developing countries such as Nigeria, these concepts of user involvement is also applicable and Interview-based user involvement technique seem to be the more appropriate method. Further research on the combination of these concepts/techniques for end user involvement should be considered or rather the creation of an advanced technique/concept for gathering end user needs and requirements for an excellent usable system in developing countries with respect to their limiting factors as mentioned in this thesis.
