True supply-chain coordination requires optimization of the entire network , not merely individual relationships between neighboring organizations. A manufacturer and distributor may successfully coordinate their decisions, yet the total supply chain can still perform poorly if suppliers, retailers, logistics providers, or other stages pursue objectives that conflict with end-to-end performance.
The purpose of coordination is to align decisions so that each stage considers its effect on total supply-chain value and surplus. This includes synchronized demand information, inventory policies, replenishment decisions, capacity, transportation, promotions, and commercial incentives. Pairwise coordination improves local performance, but local optimization does not guarantee global optimization.
Sharing POS data is an important coordination mechanism because it increases visibility of actual customer demand. However, information sharing alone does not ensure that capacity, pricing, inventory, transportation, and incentive decisions across the whole network are aligned. The full benefit therefore occurs only when the supply chain is managed as an integrated system.
Established supply-chain coordination guidance states explicitly that it is insufficient for only two stages to coordinate and that the greatest benefit arises when the entire supply-chain network is coordinated .
