There is an ancient Greek paradox that feels increasingly relevant for our times. If a ship has every plank replaced over time, is it still the same ship?

This is the Ship of Theseus.

At first glance, this may sound abstract and removed from the everyday reality of quarterly targets and transformation agendas. But this is precisely what is unfolding inside organisations everywhere. Restructures, shifting strategies, and technology rewiring how work gets done. Over time, every plank is being replaced. And yet still, we insist we are steering the same ship.

I was speaking with a client recently, a seasoned executive not given to unnecessary drama. On paper, much of what they were responsible for looked sound. The plans were clear, performance was consistent, the strategy made sense. But underneath all that, they felt something was off. Progress felt heavier than it should, parts of the business were quietly deteriorating, and the collective mood and tone in rooms was shifting. What looked tidy in the reporting felt much messier when they were actually in it.

It is a pattern I am seeing a lot and it is rarely a capability issue. It is what happens when leaders are operating in an environment that no longer rewards linear thinking. The planks have been swapped out, but we are still navigating by the old charts.

The Illusion of Continuity

If everything is changing, what exactly are we leading?

Too many of us are still operating under assumptions that no longer hold. The most common is the belief that beneath all the disruption, there is a stable core waiting to be revealed. If we can just get through this restructure, this strategy cycle, this wave of change, we will find solid ground again.

But the ground has shifted. The hull looks the same from the outside and the name on the bow has not changed. But below the waterline, almost nothing is where it used to be. And yet the expectation on leaders remains the same: be decisive, be clear, be right. It is a standard built for a ship that no longer exists.

The Story We Are Still Inside

Here is where most of us get caught. The strategy can be sound and the numbers can look convincing, but the system is no longer responding the way it used to. We are pulling the levers that always worked, but nothing is moving the way it should.

More often than not, our default reaction is to treat this as an execution problem. Tighten the plan, gather more data, and push harder for alignment. It is the leadership equivalent of tightening our grip on a wheel that is no longer connected to the rudder.

But the real issue is rarely execution. Every organisation operates inside a shared story: who we are, what works, what success looks like, and how things get done here. Most of the time, we inherit and absorb that story rather than question it. We drink the Kool-Aid and over time, the story starts to feel like reality itself.

But these narratives do not just describe reality, they actually shape it. They influence what gets noticed and what gets ignored, and what is allowed to be true versus what is quietly sidelined. And when the environment shifts but the story underneath does not, we find ourselves making sense of the present through the lens of the past. We are reading new sea conditions through a map drawn for entirely different waters.

The longer we hold onto that map, the wider the gap becomes between what we believe is happening and what is actually unfolding around us. The version of reality that takes hold inside an organisation is not always the one that’s the most accurate, but the one that gains the most traction. Which means we are not just interpreting reality. Whether we recognise it or not, we are shaping it.

What Effective Leaders Are Actually Doing Differently

The leaders I see navigating this well are not the ones with the best data or the most conviction. They are the ones who have learned to make sense in motion.

Sense-making is not about finding the right answer, because there is no right answer. It is about constructing a coherent enough understanding to act, even when the picture is incomplete. It means seeing patterns before they are obvious. Holding competing interpretations without rushing to resolve them. Interrogating the assumptions beneath the data rather than just the data itself. And offering others a way forward when the path is not yet fully clear.

This is not indecision, it is disciplined interpretation and it is a very different skill from the one most of us were promoted for.

Three Practices That Strengthen It

·Separate signal from story. Too often, we collapse observation and interpretation into one move. But we need to slow that down. We need to get clear on what we actually know, what we think we know, and what meaning is being layered on top. The distinction matters more than it seems.

· Pay attention to the edges. Formal reporting tends to stabilise reality, but the edges reveal where it is shifting. We need to listen for informal conversations, workarounds, repeated tensions, and subtle changes in tone. The system often tells us what is changing before the data does.

· Offer provisional clarity. People do not need false certainty, but they do need orientation. We need to name what seems to be happening, what matters most right now, and what we are watching closely. Sometimes “here is what I think is going on, and here is what I am paying attention to” is enough. Clarity does not have to be final to be useful.

The Ship Is Always Changing

My view is that many of us are still trying to preserve the original ship. We’re still holding tightly to legacy structures, familiar narratives, and inherited assumptions. This is not because we are naïve, but because those anchors once worked for us. They provided orientation and helped us make sense of the world. And letting go of something that once served us well is a lot harder than it sounds.

But it is apparent that the ship has already changed so much. Every plank has been replaced, the crew is different, and the waters are different. The story that once made sense of it all no longer fits.

Perhaps the Ship of Theseus was never really about the ship. Perhaps it was about our deep need to believe that something essential remains unchanged, even when the evidence says otherwise. The planks will keep being replaced and the waters will keep shifting. The leader’s task is not to preserve what was, but to make sense of what is emerging, while still out at sea.

Where in your organisation are you still making sense of the present through a story that no longer fits?
