A new manager onboarding plan sets out how a manager spends their first 90 days leading a team they have just taken over. A good one is built from the team's records and first conversations, not a generic calendar. It names who to meet first and why, what to ask each person, one or two dated changes, and what goes in a day-90 report to the manager's own boss.
Meet everyone in your first month, but not in org-chart order: read each person's record first, and let what you find set the order.

Read each person's record first
Before your first one-on-ones, ask HR for three records on each direct report. You want months at their current level, their last two performance ratings with dates, and their last two engagement survey scores.
Check how your survey reports results before asking for scores. The US Office of Personnel Management's survey of federal employees, for example, never gives an agency data that could identify one person's answers1. If yours reports only group results, use the other two records alone. Use individual scores only if people gave them knowing their manager would see them.
Ask the outgoing manager for handover notes, and ask HR who left the team in the past year and what their exit interviews said. If someone joined recently, get their 30-60-90 day onboarding plan and take it over.
Then read the records one person at a time. A team average can look calm while two people are struggling.
ExampleOne team, two storiesAn illustrative example written for this guide, using the template's made-up sample team.
Team engagement average: 75.1 at the last survey, 68.3 at this one, a dip of about 7 points.
Ines: 88 to 59, down 29. Lucas: 55 to 40, down 15.
The other five moved 4 points or less.
The average looks routine. On its own, a 7-point dip reads like a quiet quarter.
Two people carry the drop. Ines and Lucas account for most of it, and other warning signs put both in week one.
Keep these records private
Together, they show ratings and survey results for named people. Store your copy where only you and HR can see it, and check your company's rules on personnel records first.
Decide who to meet first
Every direct report gets a first one-on-one in your first month; the records decide the order. The template checks each person for three warning signs.
The template's three warning signs
Sign
Counts when
Ask about
Engagement drop
Down 15 points or more between the last two surveys
What has changed in recent months
Stale rating
Last formal rating over 12 months old, unless they joined under 6 months ago
When they last heard where they stand
Flat tenure
24 months or more at one level, rated Meets or better, with no promotion
What a realistic next step would look like
Two or more signs: week one. One sign: later in the month, with one pointed question. None: later in the month.
Why these three? Engagement is something a manager can move: Gallup estimates that managers account for at least 70% of the variance in engagement scores2 across business units. An old rating means a year without a formal word on where someone stands.
A stalled career is a common reason to leave. In a 2022 Pew Research Center survey, 63% of US workers who quit a job in 2021 cited no opportunities for advancement3 as a reason.
Adjust the thresholds to your company. With reviews twice a year, a rating over 6 months old already means a missed one. Where senior promotions usually take 3 years, 24 months at one level may be normal.
A flag is a question, not a verdict
A drop can be a hard month at home, and flat tenure with strong ratings may be a promotion case nobody made. Ask before you act.
Run the first one-on-ones
Most people get four questions, in this order:
What are you working on right now?
What's going well?
What's getting in the way?
What do you wish I knew about this team that nobody has told me yet?
The last question brings out what no record holds, such as friction between two people or a process that quietly fails.
With a flagged report, open with what you noticed, not a number. Never read a survey score back to anyone; it breaks the trust the survey depends on. Ask what would make next month feel different, and end with one thing you'll do before you next meet, with a date.
ExampleA first one-on-one with a flagged reportAn illustrative example written for this guide. Ines is from the template's made-up sample team.
Ines has three flags: engagement down from 88 to 59, a rating 13 months old, and 29 months at her level on two Exceeds ratings.
Opening: "Things seem to have shifted for you over the last few months. What's changed?"
Later: "You've been at this level a while, with strong ratings. Have you raised a promotion before? What happened?"
Before the next meeting: ask HR when her overdue review will happen, and tell her by Friday.
No score read back. The opening names a change she will recognize, not her survey answer.
One promise, one date. It ends with something the manager owes her, by a set day.
Write down one specific thing each person said before you walk into your next meeting. Lara Hogan, a coach for managers and author of Resilient Management, also asks each new report how they like to receive feedback and recognition4. The answers start a document she keeps for each person.
Sketch days 1 to 30 once the flags are done. They're mostly meetings: your team first, then the peers your team works with most. Write days 31 to 60 after the priority one-on-ones, from what they turned up. In week one, agree with your own manager what they expect by day 90. Keep each phase to a page.

Phase
What it's for
Done when
Days 1 to 30
Priority one-on-ones in week one, everyone else by day 30
Each priority talk has a next step, or the flag proved to be nothing
Days 31 to 60
One or two changes that came out of those talks, each with a date
The people affected can see the change
Days 61 to 90
A one-page report to your own manager
It covers what you inherited, what the records showed and what you changed
Keep a copy of the day-90 report for whoever leads the team next.
Make every item an action, not a theme. "Support career growth" gives you nothing to do on Monday morning. "Take Ines's promotion case to my manager by day 45" does. Before you take a case upstairs, test it against your company's promotion criteria.
Treat career and performance talks as core work. Google's Project Oxygen, which analyzed more than 10,000 data points about its managers6, lists supporting career development and discussing performance among 10 key behaviors of its highly effective managers. Their teams were more likely to have lower turnover.
Before your first week ends
You've read each person's records one by one, not as a team average
Anyone with two or more flags has a one-on-one in week one
Each priority meeting opens with a question drawn from its flag
Everyone else has a first one-on-one booked inside the month
Your own manager has told you what they expect by day 90

How to use this template
Use the files as they are: fill in the Team Register, mark the warning signs in the Early Signal Checklist, then write the plan. Or choose Edit with AI. River asks for each direct report's time at level, last two ratings with dates and, if your company runs a pulse survey, last two scores.
A partial set is fine: River needs time at level plus one other record, and marks whatever is missing. It builds the Team Register, flags anyone with two or more warning signs, and only then drafts the Manager Ramp Plan around what the flags show.

Common questions
What should a new manager onboarding plan include?
It should say who you'll meet first and why, and what you'll ask each person. Add the one or two changes you expect to make by day 60 and what you'll report to your own boss at day 90. Name people and dates, so every line is something you can put in a calendar.
How soon should a new manager meet each direct report?
Within your first month, starting with whoever needs you most. This template puts anyone with two or more warning signs, such as a sharp engagement drop or years at one level, into week one. Everyone else gets a meeting later in the month. Tell the team you'll meet everyone this month, so nobody reads the order as a verdict.
What if my company doesn't run an engagement survey?
Work from the other two records. Time at level and the date of each person's last rating still show who has gone a long time without a promotion or a performance conversation. Mark the survey column as missing, not zero, so an empty cell never reads as a low score. Then ask about morale directly in each first one-on-one.
Can I use this if I was promoted to manage my former peers?
Yes. With former peers, start by naming the change: in each first one-on-one, say what's different now that you're their manager and what stays the same. Use the same records and questions for everyone, so your first decisions rest on something other than old friendships.
How long does new manager onboarding take?
The plan covers 90 days, but learning the job takes longer. Meeting the team and making a first change fit in that window; skills like coaching and performance reviews take practice over the first year. US federal agencies, for example, must train new supervisors within one year of their appointment7, including how to mentor employees and conduct appraisals.
Is this new manager onboarding plan template free?
Yes. Download the three Word documents and two CSV sheets with no signup. Most come filled in for a made-up seven-person team, so you can see how the warning signs and the plan work before you add your own people. Edit with AI opens the same template in a free River workspace.
What does Edit with AI do?
It opens the template in a free River workspace, where River builds the register for you. Send what you have on each person: time at level, their last two ratings and any pulse survey scores. A partial set is fine. River flags who to meet first and why, then drafts your 90-day plan around what it found.
