Start with demand and the work's complexity
A shared arrangement uses capacity across more than one client or workflow. A dedicated arrangement assigns capacity to your agreed work. Neither label tells you the hours, knowledge depth or management included. Ask for the actual operating arrangement.
List when contacts arrive, how long they take and which decisions require context. A small, irregular queue with well-documented answers has different needs from continuous technical work. If your demand is unknown, collect a sample before deciding that a particular staffing model is the answer.
Ask how knowledge and access are kept clear
In a shared model, ask how agents find the right client's instructions, separate records and recognise a request they should not handle. The question is whether the process gives the person enough context at the moment of work.
In a dedicated model, ask how knowledge is maintained when someone is away or the product changes. Assigning a person does not automatically solve backup, supervision or policy questions. Those responsibilities still belong in the scope.
Compare the management around the people
Check who controls schedules, priority, coaching and quality reviews. Some arrangements give you people to manage; others include the operating routine. Be clear about who reads the queue and who can make a staffing or process decision.
If you keep an internal specialist team, define which cases transfer and what evidence travels with them. A blended arrangement can work when its handoffs are deliberate. It becomes difficult when both teams assume the other is watching an unresolved case.
Choose a review point, not a permanent label
Agree what would justify a different arrangement: increased demand, deeper product knowledge, extended hours or repeated handoff problems. Review evidence about the workload and quality before expanding capacity.
For an initial discussion, prepare contact patterns, product complexity, working hours, access needs and the decisions you want to retain. Ask the supplier to explain the trade-offs in those terms. Culvion confirms availability and the delivery arrangement for the brief rather than promising every model for every schedule.
