concern on sustainable development. It integrates forward and reverse flows where the collaborative supply
chain takes place. Knowledge management is one important part of an organization that can improve the
effectiveness of the processes within the organization. Knowledge sharing is significant in a collaborative
supply chain since it affects the organizational performance and competitive advantage. The complexity in

supply chain management, for improving the CLSC members’ performance. The success factors have been
identified, and a framework has been presented, it consists of knowledge flows, management aspect and sociotechnical aspect.
