Why the right strategy and CEO don’t guarantee execution (part 1) 

(Part one of a two-part series that explains why the right strategy and CEO don’t guarantee execution – and what to do about it) 

A great strategy and CEO is not enough 

When execution falls short, boards look first at strategy. Is it clear enough? Ambitious enough? Well communicated? 

If strategy holds up to scrutiny, attention turns to the CEO. Capability, judgement, stakeholder management, pace. Most boards have a sophisticated framework – formal and informal – for evaluating whether the person at the top is performing. 

What boards look at far less often is the system through which the CEO operates. 

That gap is where a significant amount of organisational underperformance resides – and it is largely invisible until results have already deteriorated. 

The capability paradox 

Here is a pattern that appears with striking consistency across organisations. 

The CEO is strong. Experienced, strategic, credible with the board and external stakeholders. By any reasonable measure, they are performing well. 

Yet the organisation is not translating strategy into consistent execution. Priorities fragment across functions. Important decisions get revisited. Accountability is uneven. Transformation moves slower than it should. 

The instinct is to keep looking at the CEO – harder, more closely, with more structured criteria. But the answer is rarely there. 

The reason is straightforward: CEOs do not deliver outcomes directly. They deliver outcomes through the executive team. And the effectiveness of that team is not a function of how capable its individual members are. It is a function of how they operate together. 

This is the distinction that most performance frameworks miss. 

The right people can still be the wrong team 

The dominant idea in leadership thinking for the past two decades has been selection. Get the right people. Remove the wrong ones. The rest follows. 

This is not wrong. Who is on the executive team matters enormously. 

But it is incomplete. And in practice, an over-reliance on selection thinking produces a specific failure mode: organisations that have assembled highly capable leadership teams that do not function as teams at all. 

Research into senior leadership groups consistently finds that many executive teams are teams in name only. They are collections of functional leaders who meet regularly, share information, and return to their own domains. Interdependence is shallow. Enterprise thinking competes with functional loyalty. Collective accountability is nominal. 

In this environment, individual capability is largely beside the point. You can have five outstanding executives and still have a leadership group that fragments priorities, avoids difficult decisions and leaves cross-functional tensions unresolved. 

The question that matters is not just who is on the team. It is how the team works. 

What separates effective executive teams from capable ones 

The research on this is consistent and clear. 

Effective executive teams align around a small number of clearly defined priorities – and maintain that alignment under pressure. This sounds straightforward. In practice it requires genuine discipline, because the natural gravity of a large organisation pulls constantly toward proliferation. More initiatives, more committees, more competing demands. Effective teams resist that pull. Less effective ones don’t. 

Effective teams also make decisions that stick. Not because they avoid debate, but because debate happens openly inside the room rather than being suppressed and re-emerging as passive resistance outside it. The difference between genuine alignment and managed consensus is not visible in the meeting itself – it shows up in what happens to decisions afterwards. 

And effective teams are characterised by something harder to observe and harder to build: the combination of psychological safety and high-performance expectations. Both together. Safety without standards produces comfort without progress. Standards without safety produce compliance without candour. The teams that perform best hold both – they debate hard and trust each other enough to do it honestly. 

This last element is where many executive teams are weakest, and where the gap between appearance and reality is widest. Teams that look cohesive from the outside are often managing significant undercurrents of conflict, competition and withheld challenge. The CEO usually knows it. The board usually doesn’t. 

The CEO’s actual lever for performance 

This has a direct implication for how CEOs should think about their own role. 

The most important thing a CEO does is not set strategy. It is creating the conditions in which the executive team can translate strategy into execution. That means defining the purpose of the team clearly, establishing what collective accountability looks like in practice, and addressing misalignment and any dysfunction directly rather than managing around it. 

It also means modelling the behaviours the team needs – openness to challenge, willingness to deprioritise, accountability for outcomes rather than activity. 

CEOs who treat the executive team as a byproduct of hiring decisions – rather than as something that requires active, ongoing investment – tend to find that individual capability doesn’t aggregate into collective performance. The team becomes a coordination mechanism rather than an engine of execution. 

What this means for boards 

For boards, this reframe has practical consequences. 

When execution is uneven, the first question should not be “is the CEO performing?” It should be “is the executive team operating effectively as a collective?” These are related but distinct questions and conflating them leads to misdiagnosis. 

It also means that supporting the CEO includes supporting the CEO’s ability to build and sustain an effective executive team. That is not a soft or secondary responsibility – it is central to whether the organisation can execute. 

Boards that assess CEO performance in isolation from executive team effectiveness are assessing an incomplete picture. The CEO’s judgement, strategy and stakeholder management all matter. But they are filtered through a collective leadership system – and that system can amplify or undermine everything the CEO is trying to do. 

The quality of that system deserves direct scrutiny.
