A multilevel model of information system success in the user department: integrating job performance theory and field theory

Abstract

This study adapts from job performance theory and field theory, a multilevel model to identify and validate the antecedents and their effects on information system (IS) success in the user department. The model is validated by using hierarchical linear modelling (HLM) method with survey data of 283 user managers and 42 top managers collected from 42 manufacturing companies in China that were utilising ERP systems. The results reveal that top management support and user manager's knowledge and attitude all significantly affect the level of UDISP, and that top management support significantly moderates the relationship between user-manager attitude and UDISP, but not the relationship between user-manager knowledge and UDISP. To enhance job performance of user managers, top management should proactively support the company to provide them with training, psychotherapy, and positive developmental experiences in order to improve their knowledge and attitude about a specific job.
