Abstract-Focusing on the impact of business model (BM) on supply chain management (SCM), the paper takes a case study approach with six global apparel value networks to quantify the complexity created by the BM of a value network and to assess how SCM orientations differ among value networks owing to internal and external BM complexities. Results reveal a clear distinction among value networks in terms of BM complexities. Further, there are significant differences in areas of focus in SCM between high complex and less complex group proving that BM complexity matters significantly to SCM.Index Terms-Business model complexity, supply chain, apparel case study, value networks.
