Which approval is most important for ensuring system resources for a disaster recovery plan?

The most important approval for ensuring system resources for a disaster recovery plan is from IT management. IT management holds the key responsibility for overseeing the technological infrastructure of an organization, including the systems and resources required for disaster recovery. They have the expertise to evaluate the necessary resources, implement recovery strategies, and ensure that proper technical measures are in place to restore operations in the event of a disaster.

Furthermore, IT management is typically equipped to align the disaster recovery plan with the organization's overall IT strategy and budget. Their approval ensures that the necessary funding, personnel, and technological resources are allocated and managed effectively, which is crucial for the successful implementation of the disaster recovery plan.

While approvals from executive management and the board of directors are significant as they provide organizational support and often budgetary authority, it is IT management that directly deals with the specifics of resource allocation and operational resilience. The steering committee may offer guidance and oversight, but IT management is integral in executing the technical aspects of the disaster recovery plan.
