Your First 90 Days as a New Manager: What to Do Differently

A practical roadmap for the point at which you stop doing the work and start leading the people who do it.

The promotion was brilliant for a week. Then the reality set in. You’re now in a team leadership role, and you’ve been handed absolutely no manual at all. You’re still doing your old job essentially, just in a slightly different context, and you’re now expected to provide direction, run the one-to-ones, and keep the team motivated. You’ve been given absolutely zero training in any of that.

Here’s the good news. Your first 90 days don’t require you to have all the answers. They do require a few specific shifts to be made early on, before the old habits have a chance to set in. Get those right, and the team will trust you much sooner, and the rest of the job will be considerably easier. That’s where you need to focus.

Days 1 to 30: listen more than you lead. The instinct is to just dive in and prove yourself as quickly as possible with a huge number of changes and show that you’re the right person for the job. Don’t do that. Your first month is all about understanding.

You need to have one-on-ones with every member of the team and ask the real questions. What’s working? What’s not working? What would they have liked the prior manager to have done? You’ll learn a hell of a lot more in those conversations than you ever will in any report, and you’ll build trust simply by listening. Any changes you do make afterwards will be far more intelligent once you actually have a proper understanding of the situation.

Let go of the work that made you. This is the hardest shift and the one that confuses most new managers. You got the promotion because you were so good at the actual work. The job is now completely different. Your job is to get the team to do their work well. If you keep picking up the work because it’s quicker or because you’ll do it better yourself, then you’re effectively starving the team of opportunity, and you’re going to end up doing work that isn’t actually yours. You need to start handing things over, even if it’s uncomfortable and even if they do it differently. Your value is now in the output of the team rather than in your own output.

Days 30 to 60: make expectations clear. Once you’ve got a good understanding of the team, get absolutely clear on where you’re all heading. People can’t meet expectations they can’t see. Be crystal clear about what good looks like, how you want to communicate and what you will and won’t get involved in. Start having the proper one-to-ones (the ones that are about the person rather than the status update). Give feedback early and gently so the little things stay little. A team that knows what you expect will relax; the guessing is all over.

Days 60 to 90: build trust and step back. You’re now in the home stretch. It’s about building trust and not wanting to control everything. Back your people in public. Take ownership of the team’s mistakes rather than blaming the individual who made the mistake. Ask for honest feedback on yourself and then actually do something about it. The aim is to have a team that can work effectively when you’re not in the room, and that’s only possible when people actually feel trusted to do their jobs.

Stepping into management is one of the biggest leaps in a career and one of the least supported. You won’t get it all right in 90 days, and you don’t have to. What’s important is that you lead on purpose rather than just doing your old job with a new title. The managers who succeed aren’t the ones who never make a mistake. They are the ones who treat leadership as a skill to be learned from day one.
