(a) The mobilisation phase — This phase aims to notify the recovery teams (e.g. via a call-out tree) and to secure the resources (e.g. recovery services provided by vendors) required to resume business services.

(b) The alternate processing phase — This phase emphasizes the resumption of the business and service delivery at the alternate site and/or in a different way than the normal process. This may entail record reconstruction and verification, establishment of new controls, alternate manual processes, and different ways of dealing with customers and counterparties; and

(c) The full recovery phase — This phase refers to the process for moving back to a permanent site after a disaster. This phase may be as difficult and critical to the business as the process to activate the business resumption process.
