Abstract

The emergence of Enterprise Resource Planning (ERP) has guided organizations to focus on
ensuring their competitive advantages by utilizing its capabilities. This study proposes a
theoretical model for measuring ERP post-implementation success and presents empirical
findings using a conceptual model derived from the Delone and Mclean Information Systems (IS)
success model. Four of the model’s dimensions were identified to measure ERP system postimplementation success namely: ERP system Quality, ERP Information Quality, ERP Service
Quality, and ERP Post Implementation Benefits. The three quality dimensions of Delone and
Mclean’s model were used as independent variables to assess the effects on ERP postimplementation success. A total of 233 questionnaires were collected from ERP users at the
Commercial Bank of Ethiopia and the data was analyzed using Partial Least Square-Structural
Equation Modeling (PLS-SEM) techniques. Results show positive relationships between the
model constructs, and the model explained 59.31% of the variance in ERP system postimplementation success.
