In business continuity, you normally start by establishing which activities are critical in your business. You do this to ensure you’ll be able to recover or protect these things if disaster strikes. The process for identifying critical activities and the resources on which they depend is called business impact analysis (BIA). A BIA begins with a questionnaire and answers critical questions, such as: What protections do you currently have in place? What gaps in coverage exist? How quickly can the business regain its footing? What if we lost Warehouse X to a fire, or Office Building Y to a flood, or Network System Z to a hacker?
