The New Manager’s Guide to Leading a New Team in the First 90 Days

Stepping into a management role for the first time is exciting. It also comes with a steep learning curve that can feel overwhelming if you are not prepared.

The first 90 days in your new position will set the tone for everything that follows. How you build relationships, establish credibility, and align with organisational goals during this window will determine whether you thrive or struggle in the months ahead.

For mid level managers, this period presents unique challenges. You are often caught between senior leadership expectations and the day to day realities of your team. You need to prove yourself quickly while still learning the landscape. And you must balance the urge to make immediate changes with the patience required to truly understand how things work.

This guide breaks down exactly what you should focus on during each phase of your first 90 days. Whether you are managing a team for the first time or stepping into a new organisation, these strategies will help you build a solid foundation for long term success.

Days 1 to 30: Learn, Listen, and Lay the Groundwork

Your first month is not about making sweeping changes. It is about absorbing information, building relationships, and understanding the context you are operating within.

Align Expectations with Your Own Manager

Before you can lead your team effectively, you need to understand what success looks like from your manager’s perspective. Schedule a meeting in your first week to clarify their expectations.

Ask questions like:

• What are the immediate priorities for my role?
• Are there specific metrics I should be working toward?
• Do you expect significant changes, or are you satisfied with current operations?
• How often would you like us to meet for updates and support?

This conversation will give you a clear sense of direction and help you avoid wasting time on initiatives that do not align with organisational priorities.

Meet Your Team as Individuals

One on one conversations with each direct report should be a top priority during your first few weeks. These meetings are not about reviewing performance or discussing projects. They are about getting to know each person.

Ask about their strengths, the areas where they feel they need support, and their career aspirations. Listen more than you speak. Take notes. Show genuine interest in their perspectives.

These early conversations build trust and give you invaluable insight into team dynamics, existing challenges, and potential opportunities for improvement. For more guidance on building strong foundations with your team, explore our article on managing a new team.

Learn the Landscape

Spend time understanding the organisational policies, procedures, and tools that govern how work gets done. Review relevant strategic plans and understand how your team’s work contributes to broader company goals.

Create a reference document that includes key contacts, common terminology, and processes you will use repeatedly. This will save you time and reduce the friction of constantly asking basic questions.

Connect with Key Stakeholders

Your success as a manager depends on relationships beyond your immediate team. Identify peers in other departments and key stakeholders whose work intersects with yours. Schedule brief introductory meetings to understand their priorities and how you can collaborate effectively.

These connections will prove invaluable when you need cross functional support or buy in for future initiatives.

Days 31 to 60: Contribute, Build Momentum, and Establish Systems

By your second month, you should have enough context to begin contributing meaningfully while continuing to strengthen relationships.

Start Adding Value

Use the knowledge you have gathered to begin making tangible contributions. Participate actively in team meetings, support projects where your input can make a difference, and start tracking how your work impacts relevant metrics.

This is not about dramatic changes. It is about demonstrating competence and building credibility through consistent, valuable contributions.

Deepen Stakeholder Relationships

Continue nurturing the relationships you started building in month one. Regular communication with your manager, ongoing learning from experienced colleagues, and continued engagement with cross functional contacts will strengthen your network and support system.

Establish Performance Tracking

Develop a clear system for tracking team goals and individual performance. This might include regular one on one meetings with each team member, documented expectations, and shared visibility on key metrics.

Clear expectations eliminate ambiguity and ensure everyone understands what they need to achieve. For guidance on effective performance conversations, our article on giving and receiving feedback offers practical strategies.

Identify Quick Wins

Look for opportunities to make small improvements that demonstrate your value without disrupting established workflows. These quick wins build confidence within your team and signal to senior leadership that you are making progress.

Days 61 to 90: Lead with Confidence and Plan for Growth

Your third month marks the transition from learning to leading. By now, you should be operating with greater independence and beginning to shape the direction of your team.

Take Ownership of Projects

Shift your focus toward higher level contributions. Begin leading small projects and demonstrating your ability to guide colleagues through complex tasks. Show that you can think strategically while still managing day to day execution.

This is where the groundwork you laid in previous months pays off. The relationships you built, the systems you established, and the context you gathered all contribute to your ability to lead effectively.

Propose Meaningful Improvements

Based on your observations over the past two months, you should have identified areas where processes could be improved or workflows could be more efficient. Now is the time to propose those enhancements.

Approach these recommendations thoughtfully. Present data where possible, acknowledge potential challenges, and be open to feedback. Demonstrating that you can identify and solve problems is a key marker of managerial capability.

Demonstrate Measurable Impact

By the 90 day mark, you should be able to point to specific ways you have added value. Track metrics that demonstrate your impact and identify opportunities for long term growth and development.

This evidence will be important during any formal review conversations and will reinforce your credibility with both your team and senior leadership.

Common Challenges Mid Level Managers Face

The transition to management is rarely smooth. Here are some of the most common pitfalls and how to avoid them:

Trying to change too much too quickly. Your eagerness to prove yourself can backfire if you attempt sweeping changes before you understand the full context. Take time to learn before you act.

Neglecting your own development. Managing others requires skills you may not have fully developed yet. Communication, delegation, conflict resolution, and coaching are all competencies that require ongoing attention. Learn more about what makes a good manager to guide your growth.

Getting caught in the middle. Mid level managers often feel squeezed between senior leadership expectations and team realities. Our article on surviving middle management offers practical advice for navigating this challenge.

Underestimating the power of coaching. Many new managers focus exclusively on directing and forget the value of developing their people. Workplace coaching is one of the most effective tools for building a high performing team.

How Customised Training Accelerates Your Success

The strategies outlined above provide a solid framework, but every organisation and team is different. Generic advice only takes you so far.

Our workshops are not one size fits all. We work with you to understand your unique context and build training that addresses the specific skills you need to develop.

Final Thoughts

Your first 90 days as a new manager will be demanding, but they also represent an incredible opportunity. The habits you build, the relationships you establish, and the credibility you develop during this window will shape your trajectory for years to come.

Focus on learning before leading. Prioritise relationships over quick wins. Build systems that create clarity and accountability. And invest in your own development as intentionally as you invest in your team.
