『High Output Management』要約

Andrew S. Grove’s High Output Management, first published in 1983, draws on his experience as a co-founder and longtime CEO of Intel. The book argues that a manager’s output is the output of the teams and neighboring teams under their influence, and it builds a practical operating system around that premise. Grove introduces the idea of the limiting step in production, borrowed from manufacturing, and applies it to managerial work: identify the bottleneck in any workflow and schedule around it. He defines managerial leverage as the ratio of output to the effort a manager invests, sorting activities into high- and low-leverage categories, and urges managers to delegate, train, and perform tasks that multiply others’ effectiveness. A central framework is the distinction between process- and mission-oriented work, with Grove favoring process-oriented approaches for predictable, repeatable tasks and mission-oriented ones for novel problems. He describes managerial control through paired indicators, arguing that a single metric invites gaming while two complementary measures keep behavior honest. He explains meetings as the medium of managerial work, distinguishing one-on-ones, staff meetings, and operation reviews, and prescribes agendas and follow-ups. The book also covers task-relevant maturity, a situational leadership model in which a manager’s style shifts from structured direction to delegation as a subordinate gains competence and confidence. Grove frames performance appraisal as a two-part exercise: assessing performance against objectives and then delivering the assessment skillfully. He discusses compensation, promotion, and the importance of training as a manager’s highest-leverage activity. Written in plain, engineering-inflected prose, the book treats management as a measurable production function rather than a matter of charisma. It remains widely read in Silicon Valley and is often cited as a foundational text for operational leadership.
