Choose the work that must continue
List the processes that matter most to customers, cash flow and staff. Identify the systems, devices, electricity and connectivity each process needs. Give each process an owner and an acceptable interruption window.
Plan practical alternatives
Consider backup connectivity, device battery capacity, protected backup power and alternative communication. Test the actual equipment under a realistic workload. Confirm that the alternative network can support the applications and security controls you need.
Keep data recoverable
Backup and continuity serve different purposes. A backup helps recover data. A continuity plan explains how people continue essential work during a disruption. Test both. Record how staff access contacts and procedures if email or the identity platform is unavailable.
Run a short exercise
Choose a scenario, such as the loss of the primary internet connection. Ask staff to follow the written plan. Record failed steps, elapsed time and dependencies. Fix the most consequential gaps and repeat the exercise.
Review after changes
New applications, employees and locations can change the plan. Keep a review date and named owner. Use the downtime calculator to discuss assumptions, rather than treating its output as a forecast.
