To investigate the construct of Supply Chain Management and its antecedent construct of a Supply Chain Orientation, reliable, valid scales of each are needed. In this study, we developed measurement scales for a supply chain orientation (SCO) and supply chain management (SCM). Validity and reliability of the developed scales were established and the relationship between a SCO, SCM, and business performance was also established, providing evidence of nomological validity. The implications of these findings for managers and researchers are discussed.
