Model of post-implementation user participation within ERP advice network

Base on the social network theory, this study attempts to investigate whether the network centrality will affect the user participation in ERP system post-implementation or not. In aspects of network centrality, we used degree, closeness, betweenness and eigenvector as indicators to investigate the relationships between individual network centrality and user participation. Then we further explore the impact of user participation on system use and user satisfaction. We adopted the ERP post-implementation of TSC Company as an example. The sample data has 211 questionnaires. Our empirical results show that network centrality positively affects the three dimensions of user participation; hands-on activity and communication activity positively affect system use; user–IS relationship, hands-on activity, and communication activity positively affect user satisfaction. Through the lens of social network, we argued that ERP user network plays an important role to influence user participation in post-implementation period, which is critical for system use and user satisfaction.
