Thin Air, Clear Signals: Five Leadership Symptoms That Undermine Strategy Execution

Mountaineers learn to recognise the early signs of altitude sickness because judgement deteriorates before self-awareness does. Leadership teams face a similar problem. The behaviours that undermine strategy execution rarely announce themselves as problems. They look like commitment, focus or resilience until the team is already struggling for air. The following five symptoms are not diagnoses of failure. They are warning signs worth spotting before your team does.

1. Summit fever: the target becomes the truth

Summit fever is the determination to reach the top regardless of the evidence. In leadership terms, it is the moment a delivery target becomes more real than the customer signal, the risk register or the pilot data. A UK programme team might be pushing towards a launch date while the early user testing is politely described as mixed. The board deck says green because everyone has agreed to say green.

The antidote is a red-team hour. Within the next week, invite three people closest to the work to argue against the current plan. Give them a specific question: what evidence would persuade us to slow down, change course or stop? The purpose is not to manufacture doubt. It is to make doubt legitimate before it becomes expensive.

2. Hypoxia: honest feedback thins out

At altitude, hypoxia reduces the oxygen available to the brain. In organisations, it reduces the oxygen available to honest conversation. Leaders may still say that their door is open, but the meetings become smoother and the challenges quieter. A team that once debated priorities now agrees in public and grumbles in corridors.

The antidote is to lower the cost of dissent. Ask three people, individually, what they would say if they were not worried about the reaction. Then thank them for the answer without explaining why the concern is already covered. A short anonymous pulse question can also help: what is the one thing we are pretending not to know? The phrasing matters because it gives permission without requiring a named hero.

3. Tunnel vision: the next handhold fills the view

Tunnel vision is a natural response to difficulty. When the route is demanding, attention narrows to the next hold. In strategy execution, this appears as a team that is endlessly busy on the next sprint, the next report or the next quarterly deliverable, while losing sight of why the work matters. Activity becomes a proxy for progress.

The antidote is a horizon hour. Once this week, take the team's current task list and ask which items visibly connect to the strategic outcome and which have simply accumulated. Then remove or defer one low-value activity. The exercise is not about doing less for its own sake. It is about restoring peripheral vision. A team that can see the ridge ahead makes better decisions about the next handhold.

4. Exhaustion mistaken for commitment

There is a particular UK workplace tendency to admire visible tiredness. Late nights, full inboxes and weekend messages are read as evidence of dedication. Sometimes they are. Often they are evidence that the system is relying on individual endurance rather than good design. The team may be committed, but commitment is not the same as capacity.

The antidote is a recovery audit. Look at the team calendar for the next fortnight and identify the meetings that exist because they have always existed. Cancel one. Protect one block of focus time. Ask what would need to change for the work to be delivered without the regular surge. Tiredness is not a key performance indicator, however impressively it is displayed.

5. Snow blindness: the landscape disappears

Snow blindness occurs when the eyes are overwhelmed by glare and the contours of the terrain become invisible. Leadership snow blindness is the inability to see changes in the external environment because the internal plan is consuming all available attention. A team can become highly proficient at executing a strategy that the market has already begun to revise.

The antidote is a short external scan. Once this week, ask each member of the senior team to bring one signal from outside the organisation: a customer comment, a competitor move, a regulatory shift or a change in supplier behaviour. Discuss what it might mean for the current plan. The aim is not to react to every data point. It is to keep the contours visible.

Spotting the symptoms early

The common thread across these five symptoms is that they are easier to see in others than in ourselves. That is why a weekly discipline is more useful than an annual review. A red-team hour, a lower cost of dissent, a horizon hour, a recovery audit and an external scan are modest interventions. Together, they create a team that can notice the thin air before judgement becomes unreliable.

The best leaders at altitude are not the ones who never feel the symptoms. They are the ones who build routines that make the symptoms speak early. In strategy execution, that is not a sign of weakness. It is a form of clear-sightedness.
