What actually changed
You were promoted because you were good at the work. The job you've got now is a different job: it's getting the work done through other people, most of whom are not like you. That sounds obvious; it's the thing most new managers resist for a year.
Three shifts, in order of how hard they are:
- Days 1–30Learn, don’t change
- Weekly 1:1s with everyone in the first fortnight
- Ask what’s working, what’s in the way, how they like to be managed
- Find out what your own manager expects
- Days 30–60Set the basics
- Make expectations explicit
- Delegate the outcome, deadline and constraints
- Give small feedback early
- Days 60–90The harder conversations
- Have the one you’ve been putting off
- Ask for feedback on yourself
- Decide what you’ll stop doing
The first 30 days: learn, don't change
Resist the urge to fix things. Spend the first month understanding the people and the work.
- Set up weekly 1:1s with everyone in the first fortnight. Thirty minutes, same slot every week, their agenda. This is the single most important thing you'll do.
- Ask each person three questions: what's working, what's in the way, and how they like to be managed. Write the answers down. You'll be surprised how different they are.
- Learn how each person works. If your team has taken DISC, MBTI, Insights or CliftonStrengths at some point, dig the reports out; they're a shortcut to what you'd otherwise learn slowly. If not, watch: who wants the decision, who wants the reasoning, who goes quiet under pressure, who talks more.
- Find out what your own manager expects, in writing if you can. "Make the team successful" isn't a target.
Turn this into advice for one person on your team.
Days 30–60: set the basics
- Make expectations explicit. What good looks like, when things are due, how you want to hear about problems. Most friction in the first six months comes from unspoken expectations on both sides.
- Start delegating properly. Outcome, deadline, constraints, and then get out of the way. Adjust how you hand things over to the person: some want the goal and nothing else; some want the plan and a point of contact.
- Give small feedback early. A quiet "that meeting ran long, can you keep it to the agenda next time?" in week five is easy. The same conversation in month six, after it's become a pattern, is a performance issue.
- Sort out your own time. Block the hours for the team, including the 1:1s, before anything else gets in the diary.
Days 60–90: the harder conversations
By now you'll know where the problems are, and you'll have been putting one off.
- Have it. Whatever it is, it's not getting easier. Prepare: what happened, the impact, what you need to change. Deliver it in the way the person can hear it: direct and brief for some people, private and gentle with time to think for others.
- Deal with the former-peer thing if it's still there. If someone's testing the boundary, address it once, privately, and then be consistent.
- Ask for feedback on yourself. "What's one thing I could do differently as your manager?" Early, before you've got defensive habits.
- Decide what you'll stop doing. If you're still the best individual contributor on the team, pick the thing you'll hand over this month.
The mistakes everyone makes
Managing everyone the same way. Usually the way you'd want to be managed. Half the team will quietly disengage.
Avoiding the conversation. Feedback delayed is feedback compounded.
Doing the work yourself. It feels productive. It isn't the job.
Over-communicating certainty. You don't have to have an answer to everything. "I don't know yet; I'll find out" is a fine sentence.
Cancelling 1:1s when busy. Each cancellation teaches the team they're not the priority.
Trying to be liked. Aim to be fair and clear. Liked follows, or it doesn't, and either way the team works better.
If you're managing remotely
Everything above matters more. You see less, so you must ask more. Keep 1:1s on camera, keep them weekly, and ask directly how people are finding the work; you won't catch it in the corridor because there isn't one.
The thing to remember
Good managers aren't the ones with the most answers. They're the ones who've worked out what each person on their team needs, and adjust. That's a skill, and it can be learned in weeks rather than years if you go looking for it deliberately. Start with the three questions, keep the 1:1s, and be fluid about the rest.
Questions managers ask
How do I manage people who used to be my peers?
Name it once, directly: the relationship has changed and you'll be fair about it. Then be consistent. Don't pretend nothing's changed, and don't overcorrect into distance. Fairness, visibly applied, is what makes it work.
What if someone on my team is more experienced than me?
Good. Your job isn't to know more than them; it's to remove what's in their way and make sure their work counts. Say that to them, and mean it.
How much should I still do the actual work?
Less than you want to. In most roles a new manager should spend the majority of their time on the team within three months. If you're still the best individual contributor at month six, something's wrong.
I feel like an impostor. Is that normal?
Almost universal. It fades as you get evidence you can do the job, which comes from doing it, not from waiting to feel ready.
