Purpose of a BIA (Business Impact Analysis)
A Business Impact Analysis is the “process of analyzing the impact over time of a disruption on the organization”. (ISO 22300:2021)
The purpose is to identify critical business processes for which you need to implement a Business Continuity Plan (BCP).
Process responsible users (BIA responsible users) must fill in a matrix to qualify the impact of the disruption (for each impact type and downtime period).
This matrix enables to compute, for each process:
• the RTO

The RTO (Recovery Time Objective) is the time frame identified for resuming disrupted activities.
• the business impact

A business impact is the outcome of a disruption.
