The Three Tasks of Management

Definition

Management is defined not by its work or structure but by its tasks. These tasks are equally important and must be performed simultaneously, though they represent different dimensions of institutional performance: (1) ensuring the institution fulfills its specific purpose and mission (for business, economic performance); (2) making work productive and workers achieving; and (3) managing the institution's social impacts and responsibilities to the community and society it serves.

In the Book

Drucker opens Part One by stating: "There are three tasks, equally important but essentially different, which management has to perform." For business, the first task means "Every act, every decision, every deliberation of management has economic performance as its first dimension." But performance achieved through mismanaging work and workers is "illusory and actually destructive of capital even in the fairly short run."

The second task recognizes that institutions in modern society are the primary means through which individuals "find their livelihood, find their access to social status, to community and to individual achievement and satisfaction." Making the worker achieving is therefore increasingly a measure of institutional performance, not merely a cost.

The third task flows from the fundamental truth: "None of our institutions exists by itself and is an end in itself. Every one is an organ of society." The Benedictine monastery failed to remove itself from society's concerns; modern institutions cannot either. "Every institution has to have impacts on people, on communities, and on society. It has to have power and authority over people...It has to have impact on the community as a neighbor...and increasingly...it has to add concern for the quality of life."

Drucker emphasizes: "Each of these three tasks has a primacy of its own." They are not hierarchical but tensional—creating constant managerial challenge to balance all three without sacrificing any.

Why It Matters

This framework breaks management down from mystique ("leadership," "vision") into observable, actionable tasks. It prevents the common mistake of optimizing one dimension (profit, efficiency, employee satisfaction) while destroying the others. The concept applies beyond business: any institution serving a defined mission must balance purpose-fulfillment, making work meaningful, and maintaining social legitimacy. It identifies why institutions fail: not from pursuing one goal too hard, but from neglecting the others. This structure is load-bearing across sectors—schools must achieve learning (purpose), make teaching rewarding (work), and maintain community trust (social); nonprofits must deliver mission, sustain their workforce, and justify their role in society.
