以生產為主的大企業,往往在搞'Lean'的行動上墜入'Lean 自己唔 Lean 別人'的誤區。導致此情況的發生,是因為大企業的 Buyer Bargaining Power 很大,它們在搞Lean之時一定要求上游供應商作出少批量及更頻繁的送貨,而小供應商很多時都被逼做過多的庫存(當然是假設它們沒有行 TOC...哈哈),以免缺貨受罰。而這些供應商持有庫存的成本,最終亦會轉嫁回這些大企業去。

有更甚者,如果此等大企業是以 Sales Forecast 來進行生產計劃的話,整條供應鏈的形態往往會形成中間瘦,兩頭肥大的型態。總而言之,整條供應鏈的總成本,將不會因為有某一部份(很多時是生產部份)搞 Lean 而降低,因此其整體兢爭力亦不會提高。
