Business Impact Analysis Concepts

The following concepts are used to carry out the business impact analysis:

  • Recovery Point Object (RPO): RPO is how much time a company can last without its data before it affects operations. This is also known as acceptable downtime; if a company agrees that it can be without data for three hours, then the RPO is three hours. If the IT systems in a company suffer a loss of service at 13:00 hours, then the RPO would be 16:00 hours. Any repair beyond that time would have an adverse impact on the business.
  • Recovery Time Object (RTO): RTO is the time that the company has been returned to an operational state. In the RPO scenario, we would like the RTO to be before 16:00 hours. If the RTO is beyond 16:00 hours, then once again it has an adverse impact on the business.
  • Mean Time to Repair (MTTR): MTTR is the average amount of time it takes to repair...
