Quick answer. Spend your first 90 days listening before acting. Set up regular one-on-ones, learn each person's salary, tenure, and career track, understand the team's goals and who your work depends on, and budget a third to half of your week for actual management. Do not reorganize anything until you understand why it is the way it is.
The first time I stepped into a manager role, I wanted to prove I deserved it, so I showed up with a plan to fix everything in the first week. That was a mistake. The team did not need a hero with a reorg plan. They needed someone who understood how things actually worked before touching anything.
This is a guide to your first 90 days managing a marketing team, built around a simple idea: observe first, then change. You are not there to flip the table on day one. You are there to learn the people, the numbers, and the promises made before you arrived, and to earn enough trust that when you do change something, people come with you.
Start with one-on-ones, not a plan
The single most useful thing you can do in week one is book a recurring one-on-one with every person who reports to you. Not a group kickoff, not a slide deck about your vision. A private, regular conversation with each individual.In those first meetings you are mostly asking and listening. What is working, what is getting in the way, what do they wish someone would fix. And ask directly about promises the previous manager made. Someone may have been told a raise was coming, or that they would lead the next campaign. If you do not know about that promise, you will accidentally break it, and you will look like the person who took something away.You do not have to honor every promise, but you have to know they exist. A raise that was verbally agreed and never processed is a trust bomb waiting to go off. Surface it early, while you still have goodwill to spend.Learn the people from more than one angle
Your own read on someone is one data point. Gather more. Talk to your peers, to adjacent team leads, and if you can, to the former manager. You are trying to understand each person's real strengths and weaknesses, not just how they present in a meeting.At the same time, assess each person with fresh eyes. The label someone carried under the last manager may be stale or unfair. A person written off as junior might just have been stuck with junior work. Someone praised as a star might have been coasting on one old win. Form your own view, but inform it with what people who worked with them already know.Then make a deliberate list of people worth talking to beyond your direct team. Every project has peers who hold non-obvious context: the analyst who knows why a channel was paused, the finance partner who knows the real budget story. Meet them on purpose. This is the map that saves you months later.Get the money and the history straight
You cannot manage people fairly if you do not know how they are paid. Early on, learn each person's salary and how the bonus system actually works. Then build a simple picture for each report:- Tenure: how long they have been on the team and in the company.
- Growth rate: how fast they have progressed, in skill and in level.
- Last raise: when their pay was last adjusted, and by how much.
- Bonus mechanics: what actually triggers a payout, and whether it feels fair to them.
- Open promises: anything verbal that has not been made real yet.
Protect time for the job of managing
New managers, especially ones promoted from an individual contributor role, tend to keep doing the old job and squeeze management into the cracks. That does not work. Managing is the job now, and it takes real hours.Budget a third to a half of your week for management work. If you lead four people, expect to spend up to half your week on them: one-on-ones, unblocking, reviewing, hiring, and thinking about where each person is headed. If your calendar has no room for that, something has to give, and it should be the hands-on work you can delegate, not the people work you cannot.That also means being honest with your boss about capacity. If you are still expected to personally run campaigns at your old volume while managing a team, the math does not close. Name it early rather than quietly burning out in month two.Understand goals, hiring, and the channels of information
Learn what your team is actually on the hook for. Get the six-month goals in writing if you can, understand what your boss expects and what adjacent teams expect from you, then form an honest opinion about whether any of it is realistic. If the target was set by someone who is now gone, do not assume it is sane. Pressure-test it before you commit your team to it.Address hiring while you are at it. Find out which roles are open, why, and whether you should push to fill them or quietly let them go. An open headcount you inherited is not automatically a role you need. Decide on purpose.Think about each person's career track, even this early. You will not have the full answer, but you can sketch a starting path, ideally drafting it together with them. People stay for a manager who is visibly invested in where they are going. Finally, audit the plumbing: the mailing lists, the chats, the shared docs, the standing meetings. Make sure you are plugged into the channels where important information flows, so you are not the last to hear about a budget cut or a launch date that moved.Key takeaways
- Start with recurring one-on-ones and surface any promises the previous manager made before you accidentally break them.
- Learn salaries, tenure, growth, and last-raise history for each report so you can see raise conversations coming and answer them fairly.
- Budget a third to half of your week for management, understand the team's real goals, and observe before you reorganize anything.
