What to Do in Your First 90 Days as a New Manager

You Got Promoted. Now What?

Most new managers get zero training. One day you’re doing the work yourself, the next you’re responsible for other people doing it, and nobody hands you a manual. You’re expected to figure it out while still hitting your numbers.

The good news: management is a skill, not a personality trait. You can learn it the same way you learned to do the job that got you promoted in the first place. Here’s where to start.

Stop Doing the Work Yourself

The single biggest trap new managers fall into is continuing to act like an individual contributor. You were promoted because you were good at the work, so your instinct is to keep doing the work, just with extra meetings bolted on. This doesn’t scale and it signals to your team that you don’t trust them.

How to Actually Delegate

Delegation isn’t just handing off tasks you don’t want to do. It’s a deliberate transfer of ownership. To do it well:

• Be specific about the outcome you want, not the exact steps to get there. Tell people what “done” looks like, then let them figure out how.
• Match the task to the person’s current skill level. A stretch assignment is good; an assignment that sets someone up to fail is not.
• Set a check-in point before the deadline, not just a deadline. This catches problems early without you hovering.
• Resist the urge to redo their work the moment it’s not exactly how you would have done it. If the outcome meets the bar, let it stand.

A useful gut check: if you’re doing tasks that someone on your team could learn to do with reasonable coaching, you’re not delegating enough.

Feedback Is a Skill, Not a Confrontation

New managers tend to avoid feedback until it becomes a big deal, then deliver it awkwardly because they’ve been sitting on it too long. The fix is to make feedback small, frequent, and unremarkable rather than a rare, dreaded event.

Giving Positive Feedback That Sticks

Vague praise like “good job” doesn’t help anyone improve or repeat the behavior. Be specific:

• Name the exact behavior you noticed.
• Explain the impact it had.
• Say it close to when it happened, not three weeks later in a performance review.

For example, instead of “great presentation,” try “the way you walked through the risks before the recommendation made it easy for the client to say yes. Keep doing that.”

Giving Corrective Feedback Without Damaging Trust

Corrective feedback is where most new managers freeze up. A simple structure helps:

1. State the specific situation, not a pattern or generalization.
2. Describe the behavior you observed, factually, without judgment words.
3. Explain the impact on the work, the team, or the client.
4. Ask what they think happened or what got in the way, and actually listen.
5. Agree on what changes going forward.

Avoid sandwiching criticism between two compliments. Most people see through it, and it dilutes the message you actually need them to hear. Say the hard thing clearly and kindly, then move on.

Running One-on-Ones That Aren’t a Waste of Time

One-on-ones are the single highest-leverage meeting on your calendar, and they’re also the first thing to get cancelled when things get busy. Don’t cancel them. This is where trust gets built, problems surface early, and people feel heard before small frustrations turn into resignations.

Structure That Works

A one-on-one is not a status update. If you’re spending the whole time asking “what did you do this week,” you’re wasting a meeting that could have been an email. Instead, split the time roughly like this:

• First few minutes: how are they doing, genuinely, not as small talk but as information.
• Middle: their agenda, not yours. Ask what they want to talk about before you bring your own topics.
• Last portion: coaching, feedback, or career development, one topic at a time.

Keep a running document per person where you both add topics as they come up during the week. This prevents the “I can’t think of anything” moment at the start of the meeting and gives you a record of what’s been discussed over time.

Questions That Open People Up

Skip “how’s it going” and try questions that require a real answer:

• What’s the most frustrating part of your week right now?
• What do you need from me that you’re not getting?
• Where do you feel stuck?
• What would make next week easier than this one?

Leading People You Used to Work Alongside

If you were promoted from within the team, you’re now managing former peers, and that’s genuinely awkward. The relationship has changed even if nobody says it out loud.

Address it directly rather than pretending nothing’s different. A short, honest conversation with each person acknowledging the shift, and asking how they’d like to work together going forward, goes a long way. Avoid playing favorites with people you were close to before, and be extra deliberate about giving everyone equal access to your time and opportunities.

Building Confidence When You Feel Like a Fraud

Almost every new manager feels like they’re faking it for the first several months. This feeling is normal and it fades with reps, not with certainty arriving from nowhere.

Things That Help

• Write down decisions you made and how they turned out. Reviewing this later shows you that your judgment is better than you think.
• Find one or two other managers, inside or outside your company, to talk through tough situations with. You don’t have to solve everything alone.
• Ask your own manager what “good” looks like in this role. Don’t assume you know; ask directly.
• Accept that you’ll get some calls wrong. The job is course-correcting quickly, not being right every time.

The First 90 Days: A Simple Checklist

• Meet one-on-one with everyone on your team individually within the first two weeks.
• Ask each person how they like to receive feedback and recognition.
• Identify one task you’re still doing that you should hand off, and hand it off.
• Set a recurring one-on-one time with each direct report and protect it.
• Give one piece of specific, timely feedback, positive or corrective, every week.

Nobody expects you to have this mastered on day one. What matters is that you’re deliberate about learning it, rather than hoping it comes naturally over time. It doesn’t, for almost anyone, and that’s fine. The managers people remember as good ones are usually just the ones who kept trying to get better at it.
