A theoretical model to investigate factors influencing enterprise resource planning (ERP) system users’ performance in the post-implementation stage within organization is developed. The hypotheses were tested using survey data from companies that implemented ERP systems. Results from partial least squares (PLS) analyses suggest that organization climate, absorptive capacity, ease of use and system quality positively and directly affect individual performance. Additionally, the findings highlight the important role of absorptive capacity in mediating the effect of social ties on individual performance and positively impacting ease of use. Results also suggest that strong ties have a negative effect on absorptive capacity. Surprisingly, no support was found for the hypotheses that utilization mediates the effect of social ties, absorptive capacity, organization climate, ease of use and system quality on individual performance.
