Why Changing Teams Doesn’t Automatically Work

Changing teams is often described as a reset. You arrive somewhere new carrying what you’ve already proven, assuming that capability plus opportunity will naturally turn into performance. In sport, business, and leadership roles, moves are framed as progress. A clean break. Fresh energy. A chance to build on what already works.

That assumption is rarely spoken out loud, but it sits underneath most transitions.

When performance doesn’t follow, the language tightens. People talk about adaptation. About settling in. About needing time. Sometimes that’s true. But very often those explanations sit on top of something more fundamental that never quite gets named.

The real question is not whether someone can perform, but under what conditions their performance previously made sense. Because what usually changes in a move isn’t just the logo on the shirt or the name on the door. It’s the architecture that quietly held everything together.

Performance doesn’t travel as a single unit. Skill moves. Experience moves. Reputation certainly moves. What doesn’t move nearly as easily is coherence. The fit between how someone thinks, how decisions are made, how responsibility is framed, and what the system quietly legitimises under pressure.

All of that resets when you change teams, whether anyone intends it to or not.

Early on, this is easy to miss. New environments are generous. Differences are tolerated. Rough edges are reframed as freshness. There is goodwill on both sides and a shared desire for the move to work. At the same time, orientation is being rebuilt from scratch. Who matters. What really counts. Where judgement is allowed and where it isn’t. How much context is spoken, and how much is simply assumed.

None of this is written down. All of it matters.

This is why early signals are so misleading. Some people ride the lift of novelty. The energy of a new environment carries them while coherence hasn’t yet been tested. Others struggle early, not because they lack ability, but because they are recalibrating how to operate in a system that hasn’t made itself legible yet.

In both cases, short windows are over-interpreted. Early success is taken as proof of fit. Early friction is taken as evidence of weakness. In reality, neither tells you very much about whether coherence is actually forming.

You can see this clearly in elite rugby.

Blair Kinghorn’s move to Stade Toulousain worked not because he suddenly became a different player, but because the environment legitimised what he already brought. Toulouse expected decision-making autonomy, spatial intelligence, and game understanding from the backfield. Players were trusted to read, adapt, and shape what unfolded in front of them. Kinghorn’s way of seeing the game wasn’t something to be managed or simplified. It was required. Coherence increased quickly, and performance followed.

By contrast, Siya Kolisi’s move to Racing 92 never quite settled. Not because of effort, leadership, or talent, but because expectations were misaligned. Kolisi brings moral authority, relational leadership, and meaning as much as physical output. At that moment, Racing needed something more transactional and role-bound. Neither position was wrong. But the system didn’t know where to place what Kolisi naturally carries. The cost landed on the player. You saw frustration, constraint, and eventually disengagement. The move failed without anyone being at fault.

The same pattern appears beyond rugby.

In business, founders who are brilliant at creating organisations often struggle once those organisations stabilise. They are told to step back, professionalise, and trust process. Sometimes that is necessary. Sometimes it removes the very sense-making that held the system together in the first place. Performance doesn’t collapse immediately. It erodes quietly as coherence thins.

You see it again at board level. Start-ups recruit board members who have succeeded in large, established companies, assuming experience will translate. Or they recruit mirror-image entrepreneurs and double down on vision while missing containment. In both cases, success in one system is assumed to guarantee fit in another. The phase shift is underestimated. Fit is treated as static rather than situational.

I’ve lived this myself.

When Richard Burns and I moved to Peugeot Sport as reigning World Champions for 2002, we arrived believing the next challenge was shaping performance together. Building the team. Refining how things worked. With hindsight, Peugeot’s expectation was different. They wanted a fast driver to drive. Execution, not architecture. Same ambition, but different assumptions about what kind of contribution was legitimate.

At the time, we called it culture. In reality, it was expectation and role mismatch. Effort went up. Frustration followed. Performance didn’t travel because coherence didn’t.

This is where transitions become expensive.

As weeks pass, individuals often adapt harder than systems. Instincts that once steadied them are suppressed. Higher-cost ways of operating are over-used because those are the ones the environment seems to reward. Standards remain high. Commitment doesn’t disappear. But the work feels heavier than it should.

It’s also true that some people appear more resilient to change than others. They settle faster. They seem less troubled by the loss of familiarity or the absence of shared understanding. That difference is often described as resilience. In practice, it’s usually about cost.

Some people can operate for longer in environments that don’t quite fit because the mismatch asks less of them. Others are being asked to work through parts of themselves that are higher-cost, less reliable, or simply not meant to be load-bearing for long periods. From the outside, both can look like effort. From the inside, they feel very different.

Frustration rises, as explored in the previous piece. Not as resistance, but as information. During transitions, frustration often signals that coherence hasn’t yet re-formed. Instead of being read, it is reframed as part of settling in. The message is subtle but clear. Try harder. Fit yourself to what’s here. Don’t overthink it.

In the short term, that can work. In the longer term, it is costly.

Systems personalise the explanation because transitions create vulnerability on both sides. Organisations want reassurance that the decision was sound. Individuals want to justify the move. That shared pressure pushes interpretation toward mindset, resilience, or attitude rather than structure and fit. The question becomes whether the person is adaptable enough, rather than whether the environment is coherent enough.

None of this means every move should work. Some roles genuinely aren’t right. Some environments won’t fit. But assuming fit without rebuilding coherence is a gamble. When it fails, the cost is usually carried by individuals long before it is acknowledged by the system.

Changing teams exposes assumptions faster than almost anything else. It reveals what was previously doing the unseen work. Shared language. Aligned decision-making. Clear role legitimacy. Unspoken norms about pace, authority, and judgement.

When those things are missing, effort doesn’t disappear. It just becomes harder to sustain.

This is what the TDI series has been circling throughout. Not how to fix people. Not how to optimise performance. But how easily systems assume coherence, and how quickly things strain when that assumption isn’t tested.

Changing teams makes those assumptions visible.

When misalignment keeps repeating across people, roles, and transitions, what’s missing isn’t intent or capability. It’s a common language for noticing what’s actually happening. That’s where this series stops, and where the next body of work needs to begin.
