Final answer:
A regional business moving personnel to maintain operations during a severe winter storm is implementing a business continuity plan, aimed at minimizing downtime and ensuring ongoing critical operations under adverse conditions.
Step-by-step explanation:
When a regional business is expecting a severe winter storm and takes actions to move various personnel to other locations in order to avoid downtime in operations, this is an example of a business continuity plan. A business continuity plan is designed to ensure that a company can continue to function in the face of disruptions, such as severe weather. The main goal is to minimize downtime and maintain critical operations under adverse conditions. This contrasts with a disaster recovery plan, which focuses on restoring IT systems after a disaster has occurred, an incident response plan that outlines how to detect, respond to, and recover from specific security incidents, and a risk avoidance plan which would involve taking actions to avoid the risk entirely.
