Drucker's three famous sayings are as follows:

1. A successful organization must regard itself as an orchestra and not just be an orchestra. .

2. Effective managers insist on putting important things first and only do one thing well at a time.

3. Management is to define the mission of the enterprise and to motivate and organize human resources to achieve this mission. Defining mission is the task of entrepreneurs, while motivating and organizing human resources is the scope of leadership, and the combination of the two is management.

Drucker's performance spirit

In Drucker's philosophy, the "ultimate mission" of managers is performance. The so-called performance means achievements and benefits. Used in economic management activities, it refers to the results and effectiveness of social and economic management activities.

As a manager, he must be responsible for the final performance, because performance is the key to organizational development. To examine whether an organization is successful, it depends on whether it can enable ordinary people to achieve more than they think they can. Achieve better performance.

Therefore, managers have an unshirkable responsibility for this. If managers do not pursue high performance, it means that the company cannot achieve its goals, cannot achieve effective management, and cannot improve efficiency.

Therefore, Drucker emphasized the establishment of a performance spirit in the enterprise, that is, all management activities of the enterprise should be centered on how to maximize the enterprise's performance. Managers should bring out the strengths of each member and use each person's strengths to help others achieve performance.
