First-time managers: the corrections that matter in the first 90 days

The most common management development mistake is timing. Organisations promote a strong individual contributor, let them run on instinct for a year, and then send them to a leadership programme once the patterns have set. By then the corrections are large and late.

The first ninety days are when the small corrections are cheap. Here are the ones that matter most.

From “I’ll just do it” to “I’ll help them do it”

The instinct that made someone a strong contributor — take the hard task, finish it well — is the instinct that sinks them as a manager. The correction is not to stop caring about quality. It is to notice the moment of reaching for the task, and redirect that energy into setting the other person up to do it.

This is uncomfortable at first because the output dips before it rises. Managers who are told to expect that dip push through it. Managers who are not, quietly go back to doing the work themselves.

From feedback avoided to feedback normal

New managers tend to save feedback for the review, or for the moment they are frustrated enough to raise it. Both are too late and too loaded. The correction is small and mechanical: brief, specific, frequent, and unremarkable — so that feedback becomes part of the working relationship rather than an event.

From borrowed authority to earned trust

A first-time manager often leads people who were peers last month. Leaning on the title makes it worse. The faster route is boringly practical: reliability in small commitments, visible fairness, and honesty about what they do not yet know.

How we run this

Our first-time manager programmes are spaced across the transition, not front-loaded into it. Sessions are built from the situations that cohort is actually walking into, participants apply one correction at a time between sessions, and their own managers are briefed so the reinforcement comes from above as well as from us. It is course correction, applied where it is cheapest — at the start.
