2、各環節，事實上皆需仰賴上游供應廠商的準確交期，下游企業體基本上可視為上游供應廠的客戶，通常上游供應廠為了客戶滿意度及降低無法準時交達的風險起見，直覺的反應是設法提高成品庫存水準，依此類推，當供應鏈體系拉得越長，整個體系中不是為市場需求而準備的庫存累計下來將頗為可觀，根據經濟供需理論，當市場供過於求時價格自然下滑。最後結果要不是終將成為呆滯料，要不就是在市場上降價求售，而這兩種結果都不是企業所樂見的。這類的低效率流程的衍生結果將是高庫存、交期延誤之間的惡性循環，起因皆是供應體系間的規劃工作不確實及資訊不夠透明。,任督二脈 SCM (Development - Fulfillment),SCM .

9、幅度最大. 同樣的道理, 愈接近需求的前端, 其反應時間就愈快, 需求預測的準確度就愈高, 反之, 愈到末梢反應需求的速度就愈慢, 需求的預測就愈不準, 因為愈末梢受到的限制因素及累積的統計波動就愈大. 不只需求鍊如此, 供應鍊亦同, 愈接近客戶端的下游, 對於原物料供應的能見度愈低, 統計波動就愈大. 這些會影響反應時間及造成庫存問題.,SCM .
