The SGCS changes required to support the establishment of the RL system have altered the governance in the forward flow supply chain. Insurers as focal firms in the forward flow had historically had simple market governed transactions with salvage companies. In order to achieve reverse flow the SGCS was altered to a governance mechanism based on a modular model. Salvage companies codified their transactions and increased their capabilities to support the increasingly complex recovery process therefore ensuring a level of quality and service in parts supplied.
