The management of outsourcing complexity in the supply chain is a subset of complex supply chain management. Complex supply chain as a term applies to all elements required to bring a product or service to market. For instance materials, parts for assembly, assembled parts, final products/services, distribution/transportation/marketing channels; where a change in any element may impact other elements in the chain.
