Developing Instruments for Enterprise Resources Planning (ERP) Post-Implementation Failure Model

2.1. ERP Post-Implementation Failure Issues

Several ERP failure reasons have been reported. ERP failure has been attributed these reasons: inadequate implementation of ERP (Edith Galy, 2014), manager reluctant to use the system (Nunes, 2009), lack of vendor’s support (El Sayed, 2013), user resistance (Garg et al., 2013; Haider, 2013), replacement of users after training (Amin Amid et al., 2012), lack of employee morale and motivation (Edith Galy, 2014). Particularly, all failure definitions are referred to user’s unwillingness to work with ERP system. Most studies have noted that the user’s performance to work with the system is strongly related to success/failure of ERP system. Moreover, Salermon stated that ERP maintenance is key activities for ERP post-implementation. ERP maintenance covers user’s relationships and roles, software maintenance evolution and drives the user’s supports. Hence, if the maintenance activities performed inadequate, the failure will be occurred (Jose L. Salmeron et al., 2010).
