1. Identify What the Business Cannot Operate Without
Start with the activities that generate revenue and the resources required to support them. Identify the people, systems, equipment, facilities, vendors, records, and banking relationships that must remain available for the business to continue operating. Then determine how long each one can be unavailable before the disruption begins affecting revenue, customers, or contractual obligations. This is not just an equipment list. It is a prioritized map of what actually keeps the business running.
