How does business continuity relate to a service business?

Service companies must consider how they will manage their delivery of their committed service even in the event of a disaster.  Business Continuity as it relates to a service will ensure that customers are notified and suppliers are engaged in order to make arrangements to continue to meet the service delivery time frames even in the event of a disaster.  Additional preparation is required for a service being that the service to be delivered may rely on vendor engagement.
