Business Impact Analysis Process Mapping Asset Mapping Storage Mapping Data Mapping
Identify each Department’s Business Processes Identify the criticality of each Business Process Identify the interdependencies between Business Processes and Departments
Identify the Data Elements (Variables) for each Application Identify how the Data Elements are utilized with each Business Process Identify how each Department utilizes the Data Elements Identify the Criticality & Sensitivity of the Data Elements
Identify the required Storage to support the Recovery Time Objective requirements of the Business Identify the location of the Critical and Sensitive Data Identify, using Cost Benefit Analysis, the need to segregate Data by Tier
Identify the Hardware and Software (HW/SW) for each Application Identify HW/SW utilized by each Business Process Identify the criticality of HW/SW
Business Impact Analyses provide Business Processes’ and Applications’ Recovery Time Objectives (RTOs) and Recovery Point Objectives (RPOs) Business Impact Analyses can also create a bridge between Business Processes, Data Elements, Storage, and Assets
