David's Time With Peter F. Drucker 2020.8.10 冠鼎学院（GA）——识别·培养·考验未来的领导者 Productivity Information The second set of tools for business diagnosis deals with the productivity of key resources. The oldest of them——of World War Ⅱ vintage——measures the productivity of manual labor. Now we are slowly developing measurements though still quite primitive ones, for the productity of knowledge-based and service work. However, measuring only the productivity of workers, whether blue-or white-collar, no longer gives us adequate information about productivity. We need data on total-factor productivity. ——《Management Challenges for the 21st Century · Chapter4 Information Challenges》(Peter F.Drucker,1999)
