You just became a manager. Here is what to do first.
The promotion came through, the congratulations are over, and on Monday you are responsible for other people. Nobody handed you a playbook. You are still doing pieces of your old job, your former peers are watching to see who you turn into, your own manager assumes you know what you are doing, and every decision you put off is being read as a decision anyway.
The first ninety days matter more than the next two years because they set the terms. The expectations you do or do not set, the one-on-ones you do or do not hold, the first time you let something slide, the first time you overrule someone: these become the team's understanding of who you are. Most new-manager problems are not about ability. They are about doing things in the wrong order or not doing them at all.
The resources here are sequenced. What to do in the first week, the first month, and the first quarter. How to move from colleague to boss without pretending the history does not exist. How to delegate the work you are good at, hold a one-on-one that is worth the time, and give the first piece of hard feedback before it turns into a pattern. Written for people who got promoted without a playbook.
Sound familiar?
- You were promoted from within and now manage the people you had lunch with last week.
- You are still doing your old job and the new one at the same time.
- You do not know what a good first one-on-one looks like, so you have not held one.
- Someone on the team wanted your job and is not hiding it.
- You need to set expectations but do not want to come in heavy.
- Your own manager has not told you what success looks like, and you have not asked.

Questions
Before you choose
What should I do in the first week?
Meet every person on the team individually and listen more than you talk. Find out what they are working on, what is stuck, and what they need from you. Do not announce changes. Do not reorganise anything. The 90-day playbooks in this topic give you a week-by-week structure so the first month is about learning, the second about setting terms, and the third about delivering.
How do I manage people who were my peers yesterday?
Name it once, directly, and then stop apologising for it. The relationship has changed, and pretending otherwise makes everyone uncomfortable. Be consistent with everyone, including your friends, especially in the first month. The former-peers guide covers the reset conversation, handling resentment, and what to do about the friend who expects special treatment.
I am still doing my old job. How do I let go of it?
Delegate deliberately, not by dropping things. Pick the work that someone else could own, hand it over with a clear standard and a check-in date, and resist taking it back the first time it is done differently from how you would do it. The delegation material in these guides is built for exactly this handover.
Is this different from the Leading People topic?
Leading People covers the whole job of managing a team over years. This topic is narrower: the transition itself, the first ninety days, and the specific situation of being new. Start here if the promotion is recent; move to Leading People when the first quarter is behind you.
