Your first 90 days as a new manager should move through three stages: first listen and clarify what is expected of you and the team, then establish the routines that let the team work well, and finally review performance and agree development priorities. The most common mistake is changing things before you understand them; the second most common is carrying on as a high-performing individual instead of managing.
This plan is for people moving into management for the first time, whether promoted from within the team or hired from outside. For a general plan for any new job, see our 30-60-90 day plan guide.
Days 1 to 30: listen and clarify expectations
With your own manager
- Agree what success looks like for you and the team at 90 days and at a year.
- Ask which decisions you can make alone and which need their input.
- Agree how often you will meet, and what they want to hear about.
With each team member
Hold a one-to-one with everyone in your first two weeks. Useful questions:
- What is going well that we should keep?
- What gets in the way of doing your job well?
- What do you want to learn or do next in your career?
- How do you like to receive feedback?
Listen more than you speak. Take notes. Do not promise changes yet.
If you were promoted from within the team: acknowledge that the relationship has changed. Be friendly but clear that you now have a different role, including in performance conversations.
Days 31 to 60: establish team routines
By now you should see patterns. Put in place the routines a team needs to run without you in every conversation:
- Regular one-to-ones, weekly or fortnightly, that belong to the team member as much as to you
- A short team meeting with a consistent agenda: priorities, blockers, wins
- Clear ownership: who owns which work, written down
- A first delegation: hand over one recurring task you still do yourself. See how to delegate effectively
Make one or two visible improvements from what you heard in the first month. Small, fast fixes build trust.
Days 61 to 90: review performance and development priorities
- Agree goals for the next quarter at team and individual level. Our guide to team goals vs individual goals has a worked example.
- Give specific feedback to everyone, both what to continue and what to change.
- Address any serious performance issue you have seen, privately and with examples, rather than waiting for the annual review.
- Agree one development goal with each person, connected to what they told you in month one.
- Review with your own manager: what you have learned, what you have changed and what you plan next.
A 30/60/90-day plan template
| Days 1 to 30 | Days 31 to 60 | Days 61 to 90 | |
|---|---|---|---|
| Focus | Listen and clarify | Establish routines | Review and develop |
| With your manager | Agree expectations and decision rights | Share early observations | Review progress and next quarter |
| With your team | One-to-one with everyone | Regular one-to-ones and team meeting | Goals, feedback and development goals |
| Your own work | Learn the numbers and processes | Delegate one recurring task | Stop doing one thing that is no longer your job |
| Evidence of progress | Notes from every one-to-one | Routines running without reminders | Agreed goals for every team member |
Adapt it to your organisation, and review it with your manager at day 30 and day 60.
Common first-time manager mistakes
- Trying to be everyone's friend, or overcorrecting into being distant
- Solving every problem yourself instead of coaching others to solve it
- Changing processes in week one
- Avoiding the first difficult conversation
- Measuring your own worth by your individual output
Getting support
Moving into management is a change of job, not just a promotion. Leadership training for new managers can give you frameworks and practice in delegation, decision-making, motivation and performance conversations, with a personal action plan to apply them. For shorter, skills-first training, see Practical Leadership Skills.

The bottom line
Listen before you change things, build routines before you optimise them, and have the performance and development conversations early. Ninety days is enough to set the pattern for how your team works with you.
