Your first team lead role: which habits will help you, and which will get in the way

You were promoted because you were very good at your job. Now your job is different: success is measured by what your team achieves, not by what you produce yourself. Many first-time leads find that some of the habits that made them stand out as individual contributors quietly start working against them. This guide covers what changes, a simple plan for your first 90 days, and how your natural working style can help or get in the way.

The shift: from doing to enabling

Linda Hill, a professor at Harvard Business School, studied people in their first year as managers for her book Becoming a Manager. She describes the move into management as a change in professional identity, not just a new set of tasks. New managers often expect the role to bring authority and control, and discover instead that it depends on trust, relationships and getting work done through other people.

Four things that change on day one

• Your output becomes your team's output. A good week is no longer one where you finished a lot yourself. It is one where your team moved the most important work forward.
• Your calendar fills up with other people. Expect much less uninterrupted time for your own tasks, and plan for it instead of fighting it.
• Your relationships change. If you were promoted from within the team, former peers now report to you. Being liked matters less than being fair and consistent.
• Your judgment matters more than your expertise. You will often decide about work you are not the best person to do yourself. Your job is to ask good questions, weigh the trade-offs and make a call.

Your first 90 days

The idea of a structured first 90 days in a new leadership role was popularised by Michael Watkins's book The First 90 Days. Here is a simple version for a first-time team lead.

Days 1 to 30: listen

Hold a one-to-one with every person on your team, and with your own manager, before you change anything. Useful questions to ask:

• "What is going well that we should protect?"
• "What gets in the way of doing your best work?"
• "If you were in my role, what would you change first?"
• "How do you prefer to receive feedback?"

Write the answers down. Patterns across several conversations tell you far more than any single opinion.

Days 31 to 60: agree priorities and ways of working

Share what you heard, and agree with your manager on the two or three things that matter most for your team. Then agree with the team on how you will work together: how often you meet, how decisions are made, and how people should raise problems or disagree.

Days 61 to 90: make your first improvements

Pick one or two changes your team asked for in those first conversations, and deliver them. Visible improvements that came from the team's own suggestions build more trust than a new plan announced from the top. It is also a good moment to ask your team and your own manager for feedback on yourself: what should you start, stop and continue doing?

Running good one-to-ones

Regular one-to-ones are the single most useful habit for a new lead. A simple structure keeps them from turning into status updates:

1. Their topics first. Start with whatever is on their mind. It signals that the meeting is for them, not for you.
2. Progress and blockers. What is moving, what is stuck, and what you can do to unblock it.
3. Feedback, both ways. Something specific that went well, anything that needs to change, and a question about how you could support them better.
4. Growth. Every few sessions, step back from day-to-day work: what do they want to learn, and what would they like to be doing in a year?

Thirty minutes every week or two is a common rhythm. Keep short notes, follow through on what you promised, and avoid cancelling: a one-to-one that keeps getting moved tells people where they rank on your list.

Write a short "how I work" note

Many new leads find it useful to share a one-page note about how they like to work. It saves your team weeks of guessing. It might cover:

• When and how to reach you, and what counts as urgent.
• How you like to receive updates: in writing, in person, or in a weekly summary.
• How you make decisions, and when you will ask for input.
• What you expect from the team, and what they can expect from you.
• One or two of your own habits to watch out for, and permission to point them out.

Invite your team to share the same about themselves. It is a quick way to surface differences in working style before they turn into friction.

How your working style helps, and gets in the way

Your personality does not decide whether you will be a good leader. It does shape which parts of the shift come naturally and which will take deliberate effort. Here is how each of the Big Five traits tends to show up.

If you score high on Conscientiousness

Helps: you plan, follow through and set clear standards, so your team knows what good looks like.

Gets in the way: the temptation to redo work that is not quite how you would have done it, or to keep the important tasks for yourself.

Try: agree on the outcome and the deadline, then let the person choose how to get there. Review the result, not every step.

If you score high on Agreeableness

Helps: people trust you, and you notice when someone is struggling.

Gets in the way: putting off difficult conversations about performance or priorities to keep the peace.

Try: give small pieces of direct feedback early and often, so nothing builds up into one hard conversation.

If you score high on Extraversion

Helps: you bring energy, you are comfortable speaking for the team, and stakeholders know who you are.

Gets in the way: doing most of the talking in team meetings, until quieter people stop contributing.

Try: ask a question and wait, and invite specific people to share their view.

If you score low on Extraversion

Helps: you listen well and give people room to think.

Gets in the way: your team, and your own manager, may not hear enough from you about direction, progress and wins.

Try: a short, regular update to your team and to your manager, even when nothing dramatic has happened. Our guide to making your work visible has more ideas.

If you score high on Openness

Helps: you spot better ways of working and welcome new ideas from the team.

Gets in the way: changing direction too often, which leaves people unsure what matters.

Try: collect new ideas for a fixed review point, such as a monthly planning session, instead of acting on each one straight away.

If you score high on Neuroticism (emotional sensitivity)

Helps: you anticipate risks and take problems seriously.

Gets in the way: carrying the team's stress home, or reacting strongly when things go wrong, which your team will notice.

Try: build a short routine for difficult moments, such as pausing before you reply to a bad-news message, and protect your recovery time.

Delegating without dumping

New leads often hold on to work because it is faster to do it themselves. In the short term it is. In the long term it limits what the team can achieve and how much its people grow. Good delegation is clear about three things:

• The outcome: what done looks like, and by when.
• The level of authority: should they research and recommend, decide and tell you, or decide on their own?
• The check-ins: when you will look at progress together, so you are not tempted to hover in between.

Delegate work that helps someone grow, not just the tasks you would rather not do, and tell them why you chose them for it.

Giving feedback that lands

A simple, widely used structure is the Situation-Behavior-Impact model from the Center for Creative Leadership: describe the specific situation, the behaviour you observed and the impact it had.

• Instead of: "You need to communicate better."
• Try: "In yesterday's client call, you answered the pricing question before checking with finance, so we now need to correct the figure with the client."

Then ask for their view and agree on what happens next. The same structure works just as well for positive feedback, which is easy to forget when you are busy.

Leading former peers

• Acknowledge the change openly. A short, honest conversation ("this is new for both of us") works better than pretending nothing has changed.
• Be consistent. Hold everyone to the same standards, including your closest former colleagues.
• Keep confidences. You will now hear things you cannot share. Be careful about what you say in the informal conversations you used to be part of.

Look after yourself, too

The first year in a leadership role is demanding. You are learning a new job while still being responsible for results, and the work rarely fits neatly into the day. A few habits help:

• Protect thinking time. Block an hour or two a week for planning and reflection. Leading well needs time that is not spent in meetings.
• Build a peer group. Other new leads in your organisation are facing the same questions. A regular coffee with two or three of them is cheap and valuable support.
• Learn to say "not now". Protecting your team's priorities sometimes means pushing back on requests, politely and with reasons.
• Notice your own stress signals. If you find yourself constantly on edge or unable to switch off, talk to your manager, and do not hesitate to seek professional support if it persists.
