You may be measuring assignment success too early

Recent industry research reinforces this shift. ECA International highlights that employee experience now spans the full assignment lifecycle, from preparation through to repatriation, and is directly linked to early termination and performance outcomes. EY’s 2026 mobility research shows that 80% of employees are more likely to stay with their employer following a positive mobility experience, while 95% say trust influences their willingness to relocate again. These are not peripheral measures. They are indicators of assignment success, retention and programme effectiveness.

The move is working. The assignment is not

Global mobility services have become more structured, more consistent and more reliable in delivering the move itself. Processes are clearer, compliance is stronger, and relocation is rarely where assignments fail. The issue is not whether the move happens. It is whether the assignment works once it has.

This is where the gap is becoming more visible. Organisations continue to invest in international assignments to deploy talent, support expansion and drive business growth, but the conditions required for those assignments to succeed are not always fully supported once the employee has arrived. The expectation is often that performance begins immediately, despite the reality that the individual is navigating a new environment, new systems, and a different way of living and working.

Where assignment risk actually sits

Recent research highlights where this risk sits. AXA Global Healthcare has identified that family concerns, cultural adjustment and social isolation are among the most common drivers of early assignment termination. These factors sit outside traditional relocation delivery, yet they directly influence whether an assignment is completed successfully.

This is reinforced by wider industry data. ECA International notes that employee experience now spans the full assignment lifecycle, including preparation, relocation, adaptation and repatriation, and is directly linked to performance outcomes and early assignment failure.

At the same time, employee expectations have shifted. EY’s latest global mobility research shows that 80% of employees are more likely to stay with their employer following a positive mobility experience, while 95% say trust influences whether they would accept another assignment. This places greater emphasis on how the assignment is experienced, not just how it is delivered.

Why delivery alone is not enough

The challenge is that many global mobility programmes are still structured around delivery. They are designed to manage relocation, immigration and compliance effectively, but not always to support what follows. Once the employee arrives, support often reduces, while expectations increase. The employee is expected to perform quickly, integrate into the business and settle into a new environment, often at the same time.

This is where service areas that are often treated separately begin to converge. Relocation may deliver the move, immigration may secure the right to work, and policy may define the framework, but the employee experiences all of this as one journey. For senior or complex moves, VIP support may be introduced, but even then, continuity beyond arrival is not always consistent.

When these elements are not connected, gaps begin to appear. The move is complete, but the experience is fragmented. The employee has what they need on paper, but not always what they need to operate effectively in reality.

The gap between what is measured and what matters

This creates a disconnect between what organisations are trying to achieve and how programmes are structured to support it. Mobility is being used as a strategic tool to deploy talent, but the support model does not always reflect the realities of international working and living.

There is also a measurement gap. Organisations tend to track what is visible and easy to report, such as cost, timelines, compliance and policy adherence. However, the factors that determine whether an assignment works are less visible. They sit in areas such as cultural integration, family stability, confidence, wellbeing and the ability to operate effectively in a new environment.

ECA’s recent data shows that a majority of organisations now place significant importance on employee experience when assessing mobility success. However, this is not always reflected in how programmes are designed or delivered in practice.

What this means for global mobility

If talent experience is part of how success is measured, it needs to be treated as part of how assignments are managed. That means extending focus beyond relocation delivery and into what enables the employee to function, contribute and remain engaged throughout the assignment.

A successful assignment is not just compliant, delivered or on time. It is one where the employee can perform effectively, the family is settled and supported, and the assignment runs its course without disruption. Anything less introduces risk, not just to the assignment itself, but to the wider objectives it was intended to support.
