Service Center

Definition and scope

Service Centers are in charge of the delivery of services to one or several customers.
Service Centers may be hosted on customer premises or at the service provider’s offices (remote service providing).
Service Centers are steered by the service provider.
These added-value services are carried out from start to end and they are industrialized and measurable.

Setting up a service center allows the following:

  • Improve the way customers and subcontractors work together
