The output of BCM will be a business continuity plan (BCP). The BCP is a document
that provides the recovery details for the business to undertake during a disaster. Say, for
example, in a bank, the foreign exchange department is valued as critical, and in case of
a disaster, the business decides to shift its operations to another country. This document
consists of the details around how they plan to do it, not from an IT perspective but from
a business perspective.
The corresponding plan for the IT service provider is the IT service continuity plan
(ITSCP). It is derived from the BCP and aims to support the BCP activities. In the earlier
example, the business’s plan is to move foreign exchange operations to another country.
The ITSCP will support it by developing the list of activities it will take to shift operations
to another country. An ITSCP for this scenario could be something like “inform other
country’s IT team on the BCP invocation, route all traffic to another country, retrieve data
from backup, and perform tests.”
ITSCM covers all service assets, including infrastructure, applications, networks,
technical teams, and other items that contribute to a service. The BCM is responsible for
taking care of seats, users, and other items relating to business processes.
The scope of ITSCM process extends to the following items:
1. Development of ITSCM and ITSCP, and these would
eventually become a part of the customer’s BCM process and
BCP document
2. Business impact analysis (BIA) to identify business impact
when IT service is nonoperational
