Leadership Transitions: One of the Most Overlooked Risks in Organisations

Leadership transitions are often treated as milestones in organisational life. A promotion is announced, a new executive joins, or a successor steps into a critical role.

The appointment is usually the culmination of an extensive process involving search firms, assessments, interviews and board deliberation.

Yet once the announcement is made, attention frequently shifts to the next priority.

This is where an important risk begins.

Leadership transitions are not routine events. They are periods of organisational sensitivity, and evidence suggests they are far more fragile than many organisations assume.

Key Insight

• Leadership transitions represent one of the most sensitive periods in an organisation's leadership lifecycle.

• Research suggests 30–50% of CEO transitions are considered unsuccessful within the first 18 months.

• Nearly half of senior executives leave their roles within a similar timeframe.

• The greatest risk is rarely selection. It is the integration period that follows.

The Scale of Leadership Transition Risk

Leadership turnover is not unusual, even at the most senior levels of organisations.

In 2024 alone, 156 new chief executives were appointed across Fortune 500 companies, illustrating how frequently organisations must navigate leadership change at the very top.

What is more striking is what happens after those appointments are made.

Research from McKinsey & Company suggests that between one-third and one-half of CEO transitions are regarded as disappointing or unsuccessful within the first eighteen months.

Analysis discussed in Harvard Business Review similarly notes that nearly half of senior executives leave their roles within the same timeframe, whether through dismissal, resignation, or mutual agreement.

In this context, failure does not necessarily mean dismissal. It may also include underperformance, loss of confidence from boards or stakeholders, or an early departure from the role.

Taken together, these findings highlight a persistent pattern: the greatest challenge in leadership change is rarely the selection process. It is the transition that follows.

Why Leadership Transitions Are Challenging

From the outside, senior leadership roles often appear to be natural progressions. A capable executive steps into a larger mandate and continues performing at the level that earned them the promotion.

In practice, the shift is rarely so straightforward.

When leaders enter a new role, expectations rise immediately. Visibility increases. Stakeholder relationships evolve. Decisions carry broader organisational consequences.

At the same time, leaders must interpret unfamiliar organisational dynamics, navigate internal politics, and establish credibility with teams that may have different expectations or loyalties.

These pressures create a uniquely demanding period.

Even highly capable leaders often find themselves grappling with questions that have less to do with technical capability and far more to do with judgement and influence:

• How quickly should early decisions be made?

• Which stakeholders require immediate attention?

• What signals establish credibility without destabilising existing relationships?

• How should strategy be interpreted within a new organisational context?

These questions rarely have simple answers.

Organisational Cost of Unstable Transitions

When leadership transitions falter, the consequences extend beyond the individual leader.

Strategic initiatives may lose momentum. Stakeholder confidence can weaken. Teams may experience uncertainty about direction and priorities.

In some cases, instability at senior levels can trigger broader organisational disruption, including the departure of key team members or delays in strategic execution.

Organisations are increasingly aware of these risks. Yet their responses often remain uneven.

Considerable effort is typically invested in selecting the right leader. Search processes are rigorous, and succession planning receives significant attention.

What is less consistently addressed is how leaders are supported once the role begins.

The Overlooked Phase: Leadership Integration

The early months of a leadership role are not simply a continuation of previous performance. They represent a period of integration.

Leaders must quickly develop an understanding of organisational context, align expectations with key stakeholders, and establish patterns of influence that will shape their effectiveness for years to come.

The challenge is rarely capability. More often it is the complexity of integrating into a new leadership environment while continuing to deliver results.

When this process is approached deliberately, transitions can become moments of renewal. Leaders gain clarity more quickly, relationships stabilise, and organisational momentum strengthens.

When it is left largely to chance, transitions may take far longer to stabilise and in some cases fail to do so altogether.

Why Leadership Transitions Matter

Leadership transitions are rarely neutral events.

Handled well, they create opportunities for renewal, alignment and strengthened leadership capability. Handled poorly, they can introduce instability at precisely the moment when organisations require clarity and direction.

The evidence suggests organisations would benefit from paying as much attention to leadership integration as they do to leadership selection.

After all, appointing the right leader is only the beginning. The real test lies in how successfully that leader steps into the role that follows.
