I have a problem in BIA analysis. Analyzes an exemplary process: customer service at the financial point - stationary. The process is carried out, for example, in 10 locations in the country. In case of threats related to a specific point, e.g. a fire, only one facility loses. However, in the event of a ransomware attack or a complete failure of our ISP, none of the 10 work. What data related to the interruption of customer service should be taken into account in the analysis? Analyze the entire department or a single stationary service point? Please help!
