It is much harder to get rid of five extra pounds than it is not to put them on in the first
place. In no other area is it as true as it is in cost control that an ounce of prevention is
worth a pound of cure. No matter how well structured the organization, its cost-
effectiveness needs to be looked at again and again.
Peter Drucker
减少5磅的体重比事先不增加它要困难得多。“预防为主，治疗为辅”这句话最适用于成本控制。无论组织
结构多么完善，都需要反复检查其成本控制的有效性。
