BCM policy and a DR policy

Answer:

First it is important to note that both Business Continuity Management (BCM) policy and Disaster Recovery (DR) policy are top-level documents, covering management intentions. For operational purposes, i.e., detailed step-by-step activities and responsibilities, you also have to consider Business Continuity (BC) plans and Disaster Recover (DR) plans.

Considering that, the Business Continuity Management (BCM) policy is a more comprehensive document, covering management intentions regarding keeping processes and services running at minimum agreed levels after a disruptive event, and returning them to normal operation as quick as possible, while the Disaster Recovery (DR) policy focuses on management intentions regarding only the recovery of infrastructure (e.g., physical and IT infrastructure).

Reg arding documentation, you can have a single document to cover both issues, being the DR policy a section of the BCM policy.
