Whether you’re stepping into management for the very first time or you’re an experienced leader hiring new people into your team, those first six months of bringing a new team together as a cohesive group matter.

These are the months when old habits and operating practices will not work. When new players enter, new dynamics emerge. And as a leader whose job includes influencing and managing people, what made you successful as an individual contributor will not be enough now. Your success is no longer measured by what you do, but by how well others can succeed together when the sum becomes greater than the individual parts.

Over the years, I’ve seen the same patterns repeat themselves. Talented, capable, high-potential leaders fall into predictable traps not because they’re careless, but because no one ever taught them how different the role of a manager truly is.

Here are the five biggest mistakes I’ve seen new managers make in their first six months and what to do instead.

1. Relying on the Skills That Got You Promoted

Many new managers double down on what worked before: their expertise, work ethic, and ability to execute.

The problem? The moment your primary responsibility becomes leading others toward shared outcomes, the job fundamentally changes.

Instead of asking:

• How can I do this better?

You must start asking:

• How do I create clarity, alignment, and momentum with and through others?

This shift can feel disorienting. Without recognizing it, new managers often remain stuck in execution mode, which shows up as overworking, micromanaging, and unintentionally limiting their team’s growth.

Leadership isn’t about being the best player on the field anymore. It’s about designing the conditions for others to play well. It’s about moving from the star pitcher role to the coaching role.

2. Lacking Clarity on What Actually Drives Results

In the early months, many managers feel busy and overwhelmed but not effective.

Why? Because they lack clarity on:

• What truly drives business results
• What the real goals are (versus background noise)
• Where to focus their team’s limited time and energy

Without this clarity, teams spin their wheels. They chase activities instead of driving outcomes. Goals are set for the year without being broken down into achievable milestones with clear ownership.

The result is frustration, confusion, and stalled progress.

Strong managers learn to plan the work and then work the plan. That means translating strategy into shared priorities, priorities into actions, and actions into results generated by every team member taking ownership.

3. Avoiding the Human Side of the Work

New managers are often surprised by how much of their job involves human behavior.

They’re not therapists, but they are dealing with emotions, reactivity, and interpersonal dynamics every day.

One of the most common missteps is failing to truly understand what motivates each team member. Without that insight, managers:

• Misinterpret reactions
• Think everyone sees the world as they do
• Apply a one-size-fits-all approach to leadership

When leaders don’t take the time to understand what makes each person tick, individual and team performance suffer, and trust erodes.

People don’t leave teams and companies because of the work. They leave because they don’t feel seen, understood, or supported. 

You can be intentional about learning what makes your team members tick in your first 90 days in the role. (And it’s never too late to start if you haven’t already.)

4. Filling Every Minute With Meetings

Many managers equate leadership with availability. Their calendars quickly fill with back-to-back meetings, leaving no space to think and reflect without constant urgency.

But leadership without reflection is reactive leadership, often run by unconscious habits.

Without time to step back, managers lose sight of the bigger picture. They stop noticing patterns, risks, and opportunities.

That’s like starting to run from Michigan to Florida without ever stopping to buy a plane ticket that could have gotten you there a lot faster if you slowed down to build in time for planning and reflection.

Effective leadership requires protected space for reflection, sense-making, and course correction, not just constant motion.

5. Being Unaware of Your Blind Spots

Perhaps the most dangerous mistake is assuming everyone thinks, communicates, and works the way you do.

Every leader has blind spots. New managers often don’t know what their blind spots are yet, and they don’t realize how much those blind spots shape their decisions and can undermine credibility from the get-go.

Without awareness, leaders unintentionally:

• Misread situations
• Create friction through recycling drama patterns
• Reinforce unhealthy dynamics

Growth as a leader begins with self-awareness and the humility to seek feedback before small issues become systemic problems.

If This Sounds Familiar, You’re Not Alone

These challenges are incredibly common. And the good news? They’re addressable. There are skills to build. Conscious awareness of each issue alone can start to reshape your trajectory as a team.

Leadership is not about perfection. It’s about awareness, adjustment, and growth, especially in those first six months.

If you’re ready to reflect more deeply on what might be holding you or your team back, I invite you to start with awareness.
