David's Time With Peter F. Drucker 2020.3.20 But what can strategy be based on in a period of rapid change and total uncertainty, such as the world is facing at the turn of the 21st century? Are there any assumptions on which to base the strategies of an organization and especially of a business? Are there any certainties? There are indeed FIVE phenomena that can be considered cer-tainties. They are, however, different from anything present strategies. Above all, they are not, essentially, economic. They are primarily social and political. These five certainties are: 1.The Collapsing Birthrate in the Developed World. 2.Shifts in the Distribution of Disposable Income. 3.Defining Performance. 4.Global Competitiveness. 5.The Growing Incongruence Between Economic Globalization and Political Splintering. ——《Management Challenges for the 21st Century ·Chapter2》(Peter F.Drucker,1999)
