“How often you monitor should not be based on what you believe your subordinate can do in general, but on his experience with a specific task and his prior performance with it—his task-relevant maturity…”
Task-Relevant Maturity
From High Output Management (1983). Grove’s term for the parameter that should set how closely a manager supervises a given subordinate on a given task: the more experience the person has with that specific task, the lighter the touch. The ellipsis elides Grove’s own promise to elaborate (“something I’ll talk about in detail later”); later chapters develop the framework with examples of how supervision should shift as task experience grows.
Two other quotes from this site push toward light-touch management as the default. Jim Collins reads close monitoring as a hiring failure (“The best people don’t need to be managed”). Drucker’s “Knowledge workers have to manage themselves” makes autonomy a property of the category, not the situation. Grove’s claim is more specific than either: monitoring intensity is a verdict on the task-person pairing, not the person. A strong IC doing something for the first time still needs close monitoring on that work; the same person on the tenth iteration of a familiar problem does not. The hiring failure and the early-task supervision are genuinely different situations.
The practical handle: when a new project starts, ask whether the person has shipped this exact thing before, not how senior they are. The answer often does not match the org chart.
