Fulfillment functionality
FIGu RE 3.10.4 Fulfillment functions.
Order management provides the technical order management (interfacing with the customer is part
of the customer relationship management [CRM] systems). The first step is a prequalification check of
the customer order to ensure technical feasibility. Part of the feasibility check is to provide order valida-
tion for completeness and consistency. Once the order is determined to be feasible, complete, and con-
sistent, processing can start. Order management will decompose the order into the constituent services,
provisioning and activating them using the provisioning and activation functions.
Provisioning/engineering has the task of verifying the availability, suitability, and reservation of
resources prior to changing their state. For some services, design and analysis may be required to deter-
mine which resources to assign to the service. In addition, if specific service-level commitments are
required of the service, the provisioning and engineering function needs to ascertain that the resources
used can provide the necessary service levels. For other services, the provisioning and engineering
function may be relatively trivial (e.g., assign a phone number or a free Digital Subscriber Line Access
Multiplexer [DSLAM] port) and might even be performed as part of the order management or service
activation function.
