Enterprise Resource Planning (ERP) has risen to prominence as a result of its promise to integrate business processes from upstream to downstream. The past two decades, however have witnessed complications surrounding ERP implementation; its impact on firm performance has been reported as being inconclusive. This study argues that the extent of ERP integration is a missing link in the story and aims to investigate the hypothesis that the extent of ERP integration is positively associated with plant performance. Using a global sample of 641 manufacturers this research identifies four distinct ERP integration patterns, epitomized by different extents and directions of integration and finds a significant association between the broadest degree of ERP integration and plant performance improvement.
