Leadership - Not Checklists

Leadership behaviours drive performance more than governance structures. Nowhere is this more visible than in the quality of the board–CEO relationship and the strength of the chair.

That is one of the defining insights from the 2026 IESE Survey on Boards of Directors. The research makes one point unmistakably clear: in a world of technological disruption and geopolitical volatility, leadership dynamics at the top are the primary drivers of board performance and enterprise value.

One theme stands out: the quality of leadership relationships. The relationship between the Board, the Chair, and the CEO is the strongest determinant of performance. Directors overwhelmingly highlight Board–CEO collaboration as the most critical factor, with 95% rating it essential. This includes the Board’s ability to challenge and support the CEO, contribute to leadership development, and maintain a disciplined cadence of strategic dialogue.

The Chair’s leadership is equally decisive. Directors emphasise that effective Chairs set the tone for constructive debate, cohesion, and clarity – 94% identify the Chair’s leadership as a key factor in board functioning. Boards also stress the importance of dedicating sufficient time to strategic discussions. Leadership discipline, not governance mechanics, creates the conditions for high‑quality decision‑making.

The survey also exposes leadership gaps, particularly around CEO succession. Directors point to a lack of urgency (67%), unclear processes (54%), and overly close CEO–Board relationships (48%) as the main obstacles. Succession challenges are less about frameworks and more about leadership courage, independence, and the willingness to confront uncomfortable truths.

Leadership mindset also shapes organisational resilience. Boards report increasing flexibility, more frequent strategy reviews, and deeper engagement with governments as key responses to geopolitical uncertainty. Sustainability, too, is framed as a leadership issue: 63% of directors emphasise corporate purpose and culture as the anchor for long‑term sustainability goals.

Taken together, the findings reinforce a simple truth: leadership behaviours have a greater impact on corporate outcomes than formal governance mechanisms. For Boards, this means how they challenge, support, question, and guide – not the structures they operate within.

For CEOs, the message is direct:
Your relationship with the Board is now one of the biggest determinants of your strategic freedom. The quality of challenge, trust, and alignment at the top will shape your ability to execute, innovate, and lead through disruption.

For Chairs, the implication is unmistakable:
Your leadership is the single most powerful lever for Board performance. The tone you set determines whether the Board becomes a strategic asset or a constraint.

For investors and PE partners, the stakes are commercial:
Weak leadership dynamics are now a leading indicator of value erosion long before financials show it. Board-CEO misalignment, succession hesitation, and passive chairmanship are early warning signs of strategic drift.

Leadership dynamics are now your greatest source of competitive advantage – or your most dangerous blind spot. If collaboration at the top, chair strength, and succession courage are the true drivers of performance, they cannot be left to chance. This is the moment to take a hard look at the leadership relationships that shape your organisation’s future.

We see it every day: leadership gaps turn into strategic risks quickly, and organisations accelerate just as fast once those gaps are closed. If you are ready to raise your leadership game, we’re here to help you make that shift with clarity, pace, and impact.

Leadership is an asset and should not become a liability.
