3.6.1 Service Portfolio management:
A)Purpose of Service Portfolio Management
Purpose of is to make sure that the service provider
has got the perfect set of services so that it can balance
the investment in IT with the capacity to get the desired
business outcomes. It keeps a track of the investments in
services throughout their lifecycle
Service portfolio also makes sure that services are
defined clearly and linked to the achievement of business
outcomes, thus ensuring that all design, transition and
operation activities are in line with the value of services.
B)Objectives of Service Portfolio Management
To develop and maintain a Service Portfolio that provides
a complete picture of all services including their status.
To establish conditions and requirements for inclusion
of new services in the Service Portfolio.
To ensure a Service Catalogue is developed and managed
as part of the Portfolio.
Agree on the rules for transferring services to the
Service Catalogue as they move into transition and out of
the Catalogue and as they move into retirement.
To ensure that the Service Portfolio meets the functional
and performance requirements of its users and that its performance,
availability and security meet agreed requirements.
To ensure that management reports are produced in line
with agreed reporting requirements.
C)Scope of Service Portfolio Management
All services a service provider plans to deliver, those
currently delivered and those that have been withdrawn from
The primary concern of service portfolio management
is whether the service provider is able to generate
value from the services.
Service portfolio management will therefore track
investments in services and compare them to the desired
Service portfolio management evaluates the value of
services throughout their lifecycles, and must be able to
compare what newer services have offered over the retired
services they have replaced
D) Service Portfolio
A Service Portfolio is a complete list of services regardless
of where they are in their life cycle (i.e. planning, development,
production, retired). The Service Portfolio includes the service
pipeline, a service catalog, and a list of retired services.
1)Service pipeline includes services being created for a
given market space or customer.
2)Service catalog consists of services presently active in
the service operation phase, as well as those approved in the
pipeline. The service catalog provides a description of each
service, pricing and service level commitments, and terms and
conditions. The service catalog is an important tool in service
strategy because it is the virtual projection of your actual
and present capabilities. It also serves as a service-order
and demand-channeling mechanism, as well as a visualization
tool for SPM decisions. The service catalog provides a strong
link between SPM and service level management (SLM).
3)Retired services are services no longer offered.
