Request Model

A repeatable model of handling a particular category of service request. A request model defines specific agreed tasks that need to be followed to fulfill the service request of this category. Request models can be very simple, with no requirement for authorization (for example, password reset), or can be complex with many sequential or parallel tasks that require authorization (for example, provision of an existing IT service).

Request models are the catalog of service requests from the fulfillment perspective. Usually, the request models are referenced in the connector of a Front Office catalog item (svcCatalog, connector "Open New Request").

Request models define the delivery workflow, through the list of their tasks, controlled by the task planner. Each task defined in a request model has a task category, which defines the role and behavior of the task (labor, product purchase, CMDB synchronization, and so on).
