MEF Services Lifecycle Process

Flows

MEF 50 is a specification document developed by the Service Operations Committee of the MEF that defines the Carrier Ethernet Service Lifecycle Process Model.

Abstract:

This document

specifies process

flows for the

Third Network lifecycle, including Product Service

Resource (PSR) Definition Lifecycle

and Product

Service Resource (PSR) Instance Lifecycle, examined from the perspective of external commercial product considerations and internal service and resource considerations. In addition, we examine these areas from the perspectives of TM Forum’s Strategy Infrastructure Product Lifecycle and Operations Lifecycle. The process model is composed of a series of

process flows woven together to form the

Third Network service lifecycle. Each

process flow is composed using

process elements that define processes performed within a Service Provider’s organization. At the core, a single

process describes functional activities or tasks required to deliver results or outputs. The

process flows are graphically defined using

UML activity diagrams and represent the process elements in an end-to-end

process view both across the Service Provider’s business, as well as between different

organizations such as the Service Provider and

partner or end

Customer. Therefore, each

process flow examines some specific scenario in which the

processes achieve an overall business purpose for the Service Provider (e.g.,

order handling of

Third Network services). The

TM Forum’s Business Process Framework, also

referred to as the enhanced Telecom Operations Map (eTOM) [1], has an extensive definition of

process elements and decomposition of these

process elements applicable to a Service Provider’s business. As such, this document leverages these

process element definitions as the building blocks to creating the

Third Network process flows. In a few instances,

process elements required for

Third Network did not exist in the eTOM framework and have been defined in this document.
