The BIA determines which supplier is time-critical

Not every contract needs the same depth. What matters is which external service supports a time-critical internal service and which fallback options exist.

Requirements must be verifiable

Do not demand a certificate across the board. Define which recovery targets, reporting channels, subcontractors, exercises and evidence are required for the specific service you consume.

  • BCM roles and documented plans
  • agreed emergency contacts and reporting deadlines
  • evidence of regular exercises
  • exit, replacement and data return options
