Final answer:
The BIA metric that can be used to express the longest time a business function can be unavailable without causing irreparable harm to the organization is Maximum Tolerable Downtime (MTD). It helps organizations determine the acceptable downtime for their critical functions in the event of a disruption or disaster.
Step-by-step explanation:
The BIA metric that can be used to express the longest time a business function can be unavailable without causing irreparable harm to the organization is Maximum Tolerable Downtime (MTD).
MTD refers to the longest period of time that a business function can be interrupted before it begins to cause severe damage to the organization. It helps organizations determine the acceptable downtime for their critical functions in the event of a disruption or disaster.
For example, if a business determines that its maximum tolerable downtime for its online ordering system is 24 hours, it means that the system can be down for up to 24 hours without causing significant harm to the organization.
The BIA metric that can be used to express the longest time a business function can be unavailable without causing irreparable harm to the organization is MTD, which stands for Maximum Tolerable Downtime.
The MTD is a critical part of business continuity planning and is used to determine the duration that a business process can be inoperative before the negative impact on the organization becomes unacceptable. This concept is integral to the development of recovery strategies and the prioritization of recovery efforts after an outage.
