Drucker wrote this in 1977 as a condensed teaching version of his much longer Management: Tasks, Responsibilities, Practices, intended for students and for managers coming to the subject for the first time.
The content restates the framework he developed across his career. Management is a discipline with its own body of knowledge rather than a set of personal characteristics. Its three tasks are to achieve the specific purpose of the institution, to make work productive and workers effective, and to manage the institution's social impacts and responsibilities. The business must define what its business is, which requires deciding who the customer is and what the customer considers value, and the answer is neither obvious nor stable.
The practical framework includes management by objectives and self-control, in which managers set their own objectives against the organisation's goals and measure their own performance rather than being directed; the distinction between effectiveness, meaning doing the right things, and efficiency, meaning doing things right, with the argument that the first matters more; the systematic abandonment of activities that no longer serve a purpose; the requirement that decisions specify what results are expected and be reviewed against them; and the analysis of how to make staffing decisions, which Drucker treated as the decisions managers make worst.
He also covers innovation, the management of service institutions including government and non-profits, and the responsibilities of the manager as a professional.
The book is a summary and adds nothing to the larger work it condenses. Its examples are from the 1960s and 1970s. Drucker's method is observation and assertion rather than research, and readers wanting empirical support will not find it. It remains a clear statement of the framework for someone who will not read the longer book.
Managers who want Drucker's framework in condensed form without reading the full-length treatment.
