New managers should spend their first 90 days learning the business, their team, the work system and the responsibilities that come with supervising others. The goal is not to prove authority quickly. It is to build enough context, trust and operating discipline to make sound decisions.
A practical first-90-day plan should help a new manager clarify expectations, understand performance measures, hold useful one-to-one conversations, delegate work, give feedback, manage risk and establish a small number of priorities.

What should a new manager learn in the first 30 days?
The first month should focus on listening and diagnosis. A new manager needs to understand why the team exists, who its customers are, how value is created and where the work currently gets stuck.
Start with five questions:
- What outcomes is the team accountable for?
- How are quality, service, cost, risk and employee experience measured?
- Which decisions belong to the manager, and which require escalation?
- Where do handoffs with other teams fail or create delay?
- What do employees need from their manager to perform well?
Meet each team member individually. Ask about responsibilities, strengths, barriers, workload and improvement ideas. Review current goals, customer commitments, recurring meetings, open risks and recent performance data. Avoid announcing a major reorganization before this evidence has been gathered.
New managers must also learn their legal and organizational responsibilities. In Ontario, a supervisor has duties under the Occupational Health and Safety Act. Role-specific orientation should therefore cover hazards, reporting, emergency procedures, accommodation, respectful workplace expectations, privacy, information security and any regulated requirements relevant to the team.
What should happen in days 31 to 60?
The second month should convert observation into a clear management system. The manager should agree priorities with their own leader, then explain those priorities to the team in practical terms.
This is the right period to establish operating routines:
- weekly team priorities and visible ownership;
- regular one-to-one meetings;
- a simple method for tracking commitments and risks;
- clear escalation routes;
- feedback that is specific, timely and connected to expected behaviour;
- decision records for important trade-offs.
The manager should learn to separate activity from outcomes. A busy team may still miss customer, quality or financial goals. Choose a small number of measures that show whether the work is becoming more reliable. Review them with the team, not only in reports sent upward.
Delegation is another early test. Good delegation defines the result, constraints, authority, check-in points and deadline. It does not prescribe every step. The manager remains accountable for the environment in which the work is performed, while giving employees appropriate room to make decisions.
What should happen in days 61 to 90?
By the third month, the manager should be ready to improve a limited number of issues with evidence from the first 60 days. Select one or two changes that matter to employees or customers and can be observed within a reasonable period.
Examples include clarifying a handoff, reducing approval delay, correcting an uneven workload, improving a weekly planning meeting or resolving a repeated quality problem. Define a baseline and a target before making the change. Assign an owner and review what happened.
The 90-day review with the manager’s own leader should cover:
- what has been learned about the team and operating context;
- progress against agreed outcomes;
- workforce, customer and risk concerns;
- relationships that need strengthening;
- capabilities the manager still needs to develop;
- the next 90-day priorities.
Which management skills matter most?
New managers need more than technical expertise. The Government of Canada’s Skills for Success resources highlight communication, problem solving, collaboration, adaptability and digital skills among the capabilities that support effective work. In a management role, these capabilities must be applied through conversations and decisions.
Priority skills include setting expectations, listening, coaching, resolving conflict, making decisions with incomplete information, planning work, managing performance, facilitating meetings and communicating change. Managers also need enough financial and operational literacy to understand how their team affects broader business results.
“The first 90 days should not be a performance. They should be a disciplined period of learning, relationship-building and increasingly confident decision-making.”

How should the employer support the transition?
A strong new-manager program combines structured learning with work-based support. A course alone is rarely enough. Employers should provide a written role mandate, an experienced mentor or coach, access to relevant data, regular check-ins with the manager’s leader and opportunities to practise difficult conversations safely.
Use the corporate training process to assess real needs, design role-relevant learning, enable application and embed new practices. Managers should work on live business situations and receive feedback on what they actually do.
Measure the transition through behaviour and results. Useful evidence includes the quality of objectives, frequency of one-to-one conversations, closure of agreed actions, employee clarity, escalation quality, customer outcomes and progress on the selected operational improvements.
Frequently asked questions
Should a new manager make changes immediately?
Only when safety, legal compliance, ethics or serious customer harm requires urgent action. Otherwise, diagnose the situation first and explain the evidence for any early change.
How often should a new manager meet team members?
Meet every employee individually during the first month. After that, set a regular rhythm based on the work, team size and level of support required.
What is the biggest mistake in the first 90 days?
A common mistake is acting as the team’s best technical expert instead of learning to create clarity, develop people and improve the system of work.
How should success be assessed after 90 days?
Assess understanding, relationships, management routines, risk control and measurable progress on agreed priorities. Do not rely only on whether the manager appears confident.
