Which of the following BEST measures the impact of business interruptions caused by an IT service outage?

The best measure of the impact of business interruptions caused by an IT service outage is the

sustained financial loss. This is the amount of money that the enterprise loses due to the disruption

of its normal operations, such as lost revenue, increased expenses, or reduced profits. Sustained

financial loss reflects the extent and severity of the business interruption, and theeffect on the

enterprise’s objectives and performance. Sustained financial loss also helps to determine the

recovery objectives and priorities, and to justify the investment in risk mitigation and business

continuity strategies. Reference = Risk and Information Systems Control Study Manual, 7th Edition,
