There's no 'best' management style — only the right one for this task

New managers often ask whether they should be hands-off or hands-on, a delegator or a micromanager. Andy Grove, who ran Intel and wrote High Output Management, said that's the wrong question. The right amount of oversight isn't a personality trait — it depends on what he called task-relevant maturity (TRM): how experienced and capable a specific person is at a specific task, right now.

The key word is task-relevant. A brilliant engineer with 15 years of experience has high TRM writing code but low TRM the first time they run a client negotiation. So the same person needs a light touch on one task and close, structured guidance on another — on the same day. Maturity isn't about seniority or how smart someone is overall; it resets with each new challenge.

The practical rule: when TRM is low, be structured — give detailed instructions, check in often, define exactly what 'done' looks like. As TRM rises, shift to communicating goals and, eventually, to mostly monitoring. Get this backwards and you fail twice: micromanaging an expert demoralizes them, while leaving a beginner to 'figure it out' sets them up to sink.

The common mistake is treating your style as fixed — 'I'm a hands-off manager' — when the honest answer is that good managers dial oversight up and down per person, per task.
