Within the Planning phase the IT Emergency Manual is created. This can consist of various documents, depending on the size and number of data centres. In any case, equally applicable procedures for the IT Crisis Management must be described for all scenarios. Per outage scenario (e.g., Outage DC Room 1, Outage WAN, etc.) a scenario manual should exist. This should contain detailed technical descriptions on the recovery of IT services. These descriptions must be in agreement with the coordination plans for Business Continuity Management and the plans of the IT Service Providers.
