Impact of ERP Implementation on Business Process Outcomes: A Replication of a United States Study in a Sub-Saharan African Nation

Abstract

This study is a conceptual replication of Karimi et al.’s (2007) study on the impact of ERP implementations on business process outcomes among US manufacturing firms in a Sub-Saharan African (SSA) nation. The results of the measurement model are valid and reliable, which are consistent and comparable with that of the original study, enhancing the external validity of the constructs proposed in the original model. However, only one of the four hypotheses tested in the structural model was confirmed in the current study although all four were supported in the original study. While the original model was tested on manufacturing firms in the US, the replicated study was carried out in several industries in Ghana, a SSA nation. Thus the differences in the structural model results do not invalidate the original model but suggest the need for capturing contextual or environmental variables such as culture, industry, ethical behavior, and data culture in order to enhance the external validity and theoretical contribution of the original model in the SSA context.
