David's Time With Peter F. Drucker 2020.8.6 冠鼎学院（GA）——识别·培养·考验未来的领导者 For many businesses it will be painful to switch to economic-chain costing. Doing so requires uniform or at least compatible accounting systems of all companies along the entire chain. Yet each one does its accounting in its own way, and each is convinced that its system is the only possible one. Moreover, economic-chain costing requires information sharing across; yet even within the same company, people tend to resist information sharing. Whatever the obstacles, economic-chain costing is going to be done. Otherwise, even the most efficient company will suffer from an increasing cost disadvantage. ——《Management Challenges for the 21st Century · Chapter4 Information Challenges》(Peter F.Drucker,1999)
