Global Mobility Operating Models: In-House, Outsourced or Hybrid?
Choose your Global Mobility operating model by looking at two things separately: the work that needs doing and the expertise needed to do it well. A steady workload may justify an internal role. A gap in specialist knowledge may call for external support. Both can be true in the same organization.
The number of international moves helps you estimate demand, but it does not tell you whether your team can handle the decisions involved. A capable internal team may need senior guidance on a particular project. An organization without a dedicated team may need someone to run the function.
Your operating model is the agreed setup for who leads Global Mobility, manages the work, provides specialist expertise and makes decisions. The choice should reflect your business needs, governance and organizational culture.
Separate workload from expertise
Start with the work you expect over the coming year. Include ongoing support for employees already working internationally, coordination with providers, policy maintenance, reporting and changes to existing arrangements. Counting new relocations alone can leave these activities out of the staffing discussion.
Then consider how predictable that work is. A sustained workload can support an internal position, whether full-time or part-time. Occasional peaks may call for additional capacity for a defined period. The useful measure is the time and capability required across the work, rather than a fixed number of moves per employee.
Assess expertise separately. Someone may be well equipped to coordinate assignments and support employees while needing additional advice on a complex compensation question or a policy redesign. Senior leadership may be needed to connect mobility with talent priorities, agree a direction with management or improve how the function contributes to the business.
Define the role you need before deciding to hire. Case coordination, specialist advice and strategic leadership require different capabilities. An internal hire should have a realistic scope and access to the expertise needed beyond that scope.
Compare the three operating models
These are broad approaches to organizing the function. The presence of an external tax or immigration specialist alone does not tell you which model you have.
| Model | How the work is organized | When it can fit | What needs attention |
|---|---|---|---|
| In-house | An internal team leads and manages the function, using external specialists where needed. | There is sustained work and the organization can recruit or develop the required capability. | Cover during absences, access to specialist knowledge and time for improvement alongside daily delivery. |
| Outsourced | An external partner runs most or all of the agreed function, working with internal stakeholders and specialist providers. | The organization needs a functioning service but lacks the internal expertise or capacity to provide it. | Scope, authority, availability, internal approvals and access to information must be explicit. |
| Hybrid | Internal and external teams share ongoing responsibility for defined parts of the function. | Internal capability is valuable, with continuing gaps in capacity, expertise or leadership. | Each party needs a clear remit, with agreed handoffs and a route for resolving issues between them. |
A hybrid arrangement can take different forms. An internal team might manage cases while an external partner provides ongoing senior leadership. Another organization might retain leadership internally and use external support for agreed operational activities. The allocation should follow the need.
Two organizations can need very different support
In one organization we support, there was no dedicated Global Mobility department and the necessary expertise was missing internally. Compliance was the reason for bringing us in. We now act as the organization's mobility function. The need was to provide capability that was not available in-house.
In another organization, a mobility team already existed. Our work focused on redesigning how the function operated and helping the existing team put the changes into practice.
These anonymized examples illustrate why the starting point matters. Establish whether you need someone to run the function, strengthen an existing team or deliver a specific improvement before choosing a model.
A specialist assignment does not require an ongoing arrangement
A policy review, a new policy or a complex question can be a defined assignment. Organizations of any size can need that expertise occasionally while continuing to manage their own mobility function. This is the role of Expertise On Demand.
Be equally clear about implementation. If your team lacks the knowledge or capacity to put advice into practice, include implementation support in the assignment. Agree what will be introduced, who will learn to use it and what marks completion.
Implementation is a temporary phase with an endpoint and a handover. Any need for ongoing support afterward should be assessed separately.
Where several parts of the function need to change together, the work may require a broader redesign of policies, responsibilities, processes and provider relationships. Decide who will lead that change and who will run the resulting setup. Those responsibilities may sit with different people.
Compare the full cost of the arrangement
Compare options against the same scope. An internal salary and an external fee are only parts of the picture.
For an internal model, include recruitment, training, systems and cover, as well as specialist services the team will still need. For an outsourced or hybrid model, include setup and transition, agreed service fees, additional work outside scope and the internal time needed to support the relationship.
Make that remaining internal work visible. Supplying information, making decisions, allocating costs and resolving questions with the business all take time. If these activities are missing from the comparison, an option can appear less demanding than it will be in practice.
Also distinguish the cost of running the mobility function from the costs of individual assignments. They belong in related but separate discussions: changing who coordinates an assignment does not, by itself, change the employee's compensation or relocation package.
Agree decisions and handoffs before you start
Preparing an assignment estimate, approving the budget and allocating the cost internally are separate tasks. Decide who owns each one. Apply the same discipline to policy exceptions, provider instructions and changes to an employee's arrangements.
Give the person or partner managing the work a clear mandate. Record which decisions they can make, which need internal approval and whom they should contact when a decision falls outside that mandate. Involve HR, Total Rewards, Finance, Payroll, Procurement and the business where their responsibilities intersect.
Then test whether the arrangement can be handed over. A colleague or replacement partner should be able to find the current position, the advice received, the decisions made and the next action. Agree access to records, cover for absences and how knowledge will transfer when an engagement ends.
Clear ownership becomes useful when it helps the next person act without having to reconstruct the case.
Start with a task map
Before choosing a model, list the recurring work and the projects your organization expects. For each activity, record:
- The expertise and capacity required. Include how often the work arises and whether it needs senior judgment.
- Who will do it. Name the internal role or external partner, including cover.
- Who can decide. Identify the approvals and limits that matter.
- How the work passes on. Specify the information the next person needs and where it will be kept.
Use the gaps to shape your choice. A defined question may need a specialist assignment. Several connected gaps may call for Global Mobility Transformation. Where ongoing responsibility needs to sit partly or largely outside your team, Full & Hybrid Support can be scoped around that need.
The resulting model should give your organization the capability it needs today and a clear way to adjust responsibilities as that need changes.
