The First 90-180 Days: Why Transition Coaching is Critical for New Leaders

Bringing in a new leader—whether through an external hire or an internal promotion—is a major investment. The cost of failure, both human and financial, is simply too high. A leader who struggles to transition successfully can cause disengagement, disrupt productivity, and even drive turnover. Organizations that invest in structured support for new leaders help ensure smoother transitions, stronger team alignment, and faster impact.

The High Stakes of Leadership Transitions

When a new leader steps into a role, they face a steep learning curve. They must quickly grasp team dynamics, stakeholder expectations, business priorities, and organizational culture—all while proving themselves and making key decisions. Without the right support, misalignment, frustration, and performance issues can arise, leading to setbacks for both the leader and the organization.

The reality is that leadership transitions are not just about filling a position; they are about ensuring long-term success. A struggling leader can have a ripple effect—causing confusion, disengagement, and even talent loss within the team. On the other hand, a well-supported leader can energize their team, create clarity, and drive results more quickly.

What Helps New Leaders Succeed?

Leaders who integrate successfully into their roles tend to do a few key things well:

  1. Prioritize Learning Before Acting New leaders who take time to observe, ask questions, and listen before making major decisions tend to build stronger credibility and gain better insights into what needs to be done.
  2. Build Strong Relationships Early Success in leadership is largely dependent on relationships—with team members, peers, stakeholders, and customers. Leaders who proactively connect with key players gain valuable perspectives and establish trust more quickly.
  3. Clarify Expectations and Align Goals A clear understanding of what success looks like—both from the manager’s perspective and the team’s—is essential. When expectations are misaligned, leaders can spend months focusing on the wrong priorities.
  4. Understand Culture and Unwritten Rules – Every organization has its own norms, communication styles, and decision-making processes. Leaders who take time to understand these nuances are able to navigate more effectively and avoid early missteps.
  5. Establish a Leadership Brand and Communication Rhythm – Leaders who communicate consistently, set clear expectations, and reinforce team priorities create stability. The way a leader shows up in the first few months often sets the tone for their entire tenure.

Why Organizations Should Invest in Leadership Transitions

Supporting new leaders isn’t just about setting them up for personal success—it’s about ensuring the success of the entire team and organization. When leadership transitions are handled well, companies see higher engagement, stronger team performance, and faster results. Conversely, a poorly managed transition can lead to disengagement, turnover, and costly mistakes. FranklinCovey reports that the financial impact of a failed leadership transition can reach as high as $2.7 million per executive, making it a costly risk for organizations. 

Organizations that provide structured onboarding, coaching, or mentoring for new leaders send a clear message: leadership matters, and success is a priority. By investing in their leaders from the start, companies set the stage for stronger performance and long-term stability.

The first 90-180 days can make or break a leader’s trajectory. The question isn’t whether to support new leaders—it’s whether organizations can afford not to.
