Service Fulfillment Models

Service Fulfillment is the general Administration and Operation of existing services. 

There are three generally recognized administration models; 1) The Single Administration Model, 2) Split Administration Model and the 3) Unmanaged or Self-Managed Model. 

The Single Administration Model

Historically, the administration model most used is the single-administrator model, so called because one group manages all aspects of a service's administration, operation, delivery, and content.

Split Administration Model

In a Split Administration Model, responsibilities for a delivering a service are divided between a Service owner, who administrates the service itself, and a Data owner, who operates the service and is responsible for maintaining the information stored in it. This is also known as the split-IT or the delegated model.

The driving principal behind this model is that administration of a service is best performed as close to the users of the service as possible, and delegated whenever it can be.

The Unmanaged Model

Unmanaged services, sometimes called Self-Managed in IT Education circles, are ones that are not under the control of any IT organization. IT may have initially delivered or configured the service or product, but does not exercise administrative rights, enforce security policy, monitor quality of service or take proactive measures to ensure delivery.
