Most new managers are promoted because they were excellent at their job. The assumption, rarely stated out loud, is that the skills that got you here will carry you through. They will not. Management is a different discipline, and the learning curve is steeper than it looks from the outside.
The five mistakes below are not rare edge cases. They are the default. Almost every new manager makes at least two or three of them in their first year, not because they are careless, but because nothing in the individual contributor role prepares you for them.
Why the transition is harder than it looks
As an individual contributor, your environment gives you rapid feedback. You write the code, see it run. You close the deal, see the number go up. Management is slower. The feedback loop is measured in weeks and months, and cause and effect are harder to trace. That ambiguity is uncomfortable, and many new managers cope by doing what they know, staying in the work and staying close to the output, rather than sitting with the discomfort of leading.
The five mistakes below all trace back to this same root: the temptation to manage in ways that feel familiar, rather than developing the habits that management actually requires.
The five mistakes
- 1
Trying to stay an individual contributor
Jumping back into the work feels productive. It is not. When you do the work yourself, you slow down your team, signal distrust, and neglect the management tasks that nobody else will do. Your output is now your team's output. If they are not growing, neither are you. The fix: be deliberate about where you spend your time. If you are doing more than a small amount of hands-on work, something is wrong.

Avoiding difficult conversations
Performance issues, interpersonal friction, and unclear expectations. New managers often let these fester because the conversation feels risky. The cost of avoidance is always higher than the cost of the conversation. The longer you wait, the more entrenched the problem becomes, and the more you signal to the rest of the team that poor behaviour has no consequences. The fix: hold the conversation early, when it is small. Be direct, be specific, and focus on behaviour rather than character.

Skipping 1-1s when busy
The first thing to go when the calendar fills up is often the regular 1-1. This is backwards. The busier things are, the more important it is to maintain the individual connection. Skipping sends a clear message: this person is not a priority. The fix: protect 1-1s as if they are non-negotiable. If you genuinely must reschedule, do so proactively. Do not just cancel. Use a tool like Manager Toolkit to keep notes so you can walk in prepared even if you have had a chaotic week. Keep a single action list where follow-ups from 1-1s, meetings, and retrospectives all feed into one place-so nothing gets lost between sessions.

Setting goals without involving the team
Targets handed down without context or input get complied with, not committed to. People execute the letter of the goal, not the spirit of it. When team members are involved in shaping their own goals, ownership goes up and performance follows. The fix: discuss goals with each person before finalising them. Understand what is realistic, what is stretching, and what actually matters to them. A goal that feels relevant is a goal that gets worked on.

Assuming silence means everything is fine
People who are disengaged, confused, or struggling do not always say so, especially to a new manager they do not yet trust. Silence is not a signal of health. It is often the absence of a signal, which is a problem in itself. The fix: ask directly. "What is getting in your way?" and "What is one thing I could do differently?" are simple questions that surface issues you would not otherwise hear. Build asking into your regular 1-1 rhythm. Track sentiment in your catchups and use Key Themes to spot if the same concern keeps appearing across your team.
Building the habits that prevent these mistakes
What the five mistakes have in common is that they are all habit failures, not intelligence failures. Avoiding them does not require exceptional skill. It requires consistent practice of a small number of things: holding the 1-1, having the conversation, tracking the actions, involving people in their goals, and actively listening for signals of disengagement.
The practical foundation is a reliable operating rhythm. Set a regular 1-1 cadence for each person. Take brief notes after each meeting so you can follow up. Keep a single list of open actions and review it weekly. Check in with each person on their goals at least once a quarter.
None of this is complicated. The difficulty is consistency under pressure, when the week is busy, when the project is on fire, when the easier path is to cancel the 1-1 and skip the difficult conversation. Building the habits before the pressure arrives is what separates managers who improve quickly from those who repeat the same mistakes for years. Use a Journey to structure your first 90 days with clear milestones, so you build the right habits from the start rather than learning by trial and error.
Stay on top of your management rhythm
Track 1-1s, actions, and team goals so nothing slips through the cracks.
