Role of contextual factors in influencing user evaluation of information system: an analytic hierarchical process approach

摘要

Continuous evaluation of information systems (IS) is critical for their improvement. The context in which a system is embedded is a critical determinant for evaluation of its success. The paper explores the role of contextual factors in impacting the user evaluation of IS with regards to two key dimensions: information quality (IQ) and interface usability (IU), using a multi criteria decision making (MCDM) technique, analytic hierarchical process. The contextual factors include organisation size, industry of operation, type of IS, functional area and managerial level of user. The results show that excluding industry, all contextual factors significantly influence the user perception of IS evaluation. Additionally, IQ attributes of accuracy and reliability and IU attributes of efficiency and guidance are perceived as most significant by the users for IS evaluation.
