Best Practices

• Secure executive sponsorship: BCP without leadership commitment will not be taken seriously
• Base recovery priorities on Business Impact Analysis, not assumptions or technical preferences
• Test the communication plan independently: it fails more often than the technology recovery
• Maintain contact lists as if your primary systems are unavailable (offline copies, mobile access)
• Conduct tabletop exercises quarterly at minimum: they are low-cost and high-value for identifying gaps
• Include non-IT scenarios in planning (pandemic, facility loss, key personnel unavailability)
• Define clear activation criteria so there is no ambiguity about when to invoke the BCP
• Keep the BCP document practical and actionable, not a shelf document written for auditors
• Update the BCP after every significant organizational or technology change
• Review and incorporate lessons from every exercise and every real event into the plan
