Abstract: 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; usereIS 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.
Many researchers study the key factors of how to implement enterprise resource planning (ERP) system successfully (Chou & Chang, 2008; Chung, Skibniewski, & Kwak, 2009; Morton & Hu, 2008). These successful factors may broadly be classified as human/organizational, technical, and economic ones (Chen, 2001; Sarker & Lee, 2003). While each set of factors is important, there appears to be a growing consensus among researchers that human
factors, more than technical or economic, are critical to the successof ERP projects (Alvarez, 2008; Sarker & Lee, 2003). Sarker and Lee (2003) suggest that empowering the team-members for selfmanagement and communication issues are seen as central to success of an ERP implementation project.
Salmeron and Lopez (2010) indicate that encouraging the active participation of all users involved in the process of post-implementation ERP systems is essential in the success of the ERP maintenance. To deal with technical complexity and overambitious demands associated with ERP systems, user participation is important to mitigate risk (Amrit, van Hillegersberg, & van Diest, 2013). Therefore, user participation is an important factor when implementing the ERP system.
