Abstract
User participation in the development of a system is universally prescribed as an effective strategy to ensure the success of the resultant system. However, the existing literature on the merits of user participation only provides equivocal evidence. Various analyses of this literature point out that this equivocal evidence may be due to inconsistent operational measures of the user participation and system success constructs. Planned organizational change and participative decision making, the underlying paradigms of user participation construct, suggest that the development of some information systems may require blending of users' system-related functional expertise and developers' technical expertise to ensure system success. These paradigms also maintain that in case of well-defined, structured information systems user participation should enhance the likelihood of system success through better user understanding of the need for the system and system content and objectives, user trust, and a sense of system ownership. This research also described a case study involving the development and implementation of a medical records system for a neonatal intensive care unit in a large hospital in Texas. The case study provides evidence that in systems that require incorporation of user functional expertise user participation will enhance the likelihood of system success.
