A promotion to senior leadership is often the defining moment of a career.
It comes after years of consistent performance, loyalty, and visible results. For many, it feels like validation that the late nights, tough calls, and relentless drive were finally worth it. There’s excitement about shaping strategy rather than just executing it, about having a bigger platform, and about finally being at the table where key decisions are made.
At first, it seems like the natural continuation of success. After all, if the skills and discipline that got you here worked so well, why wouldn’t they carry you forward? Yet for many leaders, the reality turns out very differently.
- Korn Ferry found CEO failure rates of 40% as far back as 2005.
- Right Management Consultants reported that nearly 30% of new managers and executives leave within 18 months.
- McKinsey, in its 2014 Leadership Transitions paper, confirmed that failure rates among newly hired or promoted executives have hovered around 40% for more than a decade.
- The Corporate Executive Board (now Gartner CEB) sharpened the picture: out of nearly 30,000 leaders studied, 50% of executives fail within the first 18 months of promotion or hire. While only 3% fail outright, almost half underperform.
- The ripple effects are profound (with direct reports of successful leaders 15% more effective and 21% less likely to quit).
Put simply, if you gather 10 newly promoted leaders, five are already struggling. One of them is close to failing. Four are surviving but underdelivering. Maybe one is truly excelling.
Yet if you asked the group, most would tell you they are “doing great,” armed with a list of initiatives and practices they’ve rolled out.
ACTIVITY, however, is not the same as IMPACT.
It often seems as though the higher an individual rises in an organization, the thinner the air gets - with what looked like a reward quickly becoming a trap.
However, the reasons for these failures are often less about competence, intelligence, or drive but more about inadaptability, as well as the non-realization that at the top table, the job changes fundamentally.
Here are common reasons many leaders stumble after earning the role they worked so hard to attain.
1. The Identity Shock at the Top
Leadership promotions demand a profound redefinition of success. At this level, operational expertise and personal execution, which drive advancement at earlier stages, quickly lose currency. In one of our recent surveys across 3 Nigerian industries involving 216 managers and leaders, we discovered that more than 70% of newly promoted leaders fail to recognize that effectiveness is measured by enterprise outcomes, cross-functional tradeoffs and collaborations, as well as long-term value creation. And leaders who cannot recalibrate their identity around these new markers are usually bound to underperform.
2. The Politics of Alignment
Leadership at the top is political by design. Every major decision typically involves competing priorities, scarce resources, and trade-offs across stakeholder groups. It requires the ability to intelligently navigate unspoken politics to avoid isolation, limited influence, and/or an accelerated exit. Sadly, only about 8% of first-time leaders are ready and able to navigate this reality pre-promotion.
3. The Challenge of Leading Through Layers
At scale, leadership effectiveness depends on systems of delegation, empowerment, and accountability. We realized that about 35% of newly promoted leaders typically remain anchored in direct problem-solving and micromanagement. These create organizational bottlenecks that slow down execution and diminish team performance. Sustainable impact thus requires leading through others - and not around them.
4. Emotional Intelligence & Trust
At this level, influence runs on trust.
A common reason executives fail is the inability to build and sustain trust. While technical brilliance may earn a promotion, without emotional intelligence (self-awareness, composure, and the ability to read people), relationships deteriorate quickly. At this level, influence runs on trust.When it breaks down, peers stop collaborating, teams disengage, and critical information no longer reaches the leader. By the time the erosion is visible, recovery is rarely possible.
5. The Relentless Need to Relearn
The requirements of senior leadership evolve faster than most leaders anticipate. This is because the executive environment is defined by shifting markets, evolving technology, and constant disruptions. This implies that enterprise roles demand continuous unlearning of outdated practices as well as acquisition of new capabilities such as cultural stewardship, external orientation, digital fluency, and strategic foresight. We noticed that more than 40% of new leaders who failed failed because they assumed that past playbooks would carry them through new contexts and therefore did not maintain this learning trajectory.
6. The Loneliness Factor
Promotion into executive roles is often more isolating than leaders anticipate. In our focus group sessions, two senior leaders noted that the peer group shrinks, and informal support that once offered candid feedback disappears. More often than not, new executives discover that there are fewer safe spaces to process doubts and test ideas - with those without cultivated external peer networks defaulting to making high-stakes decisions in a vacuum.
This often produces two predictable failure patterns and outcomes - leaders doubling down on rigid decisions to project certainty, or delaying choices out of fear of being wrong - both of which erode confidence in the leader’s judgments.
Getting It Right
Promotions into executive and leadership roles are still disproportionately based on track record within a function rather than demonstrated enterprise leadership potential. Succession pipelines reward operational heroes but fail to stress-test adaptability, influence, and collaboration - which are the very traits needed at the top.
Those who transition successfully develop the ability to:
- Shift focus from personal output to enterprise impact and strategic influence.
- Identify key players, understand their priorities, and secure coalitions early.
- Cultivate mentors, peers, and networks to test ideas and process doubts.
- Focus on shaping outcomes through others, not doing it all yourself.
- Read the room, manage relationships, and preserve credibility at every level.
- Continuously unlearn outdated habits, adopt new practices, and stay ahead of change.
- Communicate clearly, act with composure, and ensure perception aligns with intent.
