While there isn’t a specific timeframe for reviewing a business continuity plan, it should be reviewed from time to time to make sure it’s still up-to-date and relevant to existing applications and services. How often you review the plan depends on a lot of things—some say at least every year or every other year, while others say only when the organization undergoes a major change in its services or operations. A more frequent review might also be smart if the organization is located in an area where natural disasters or other disruptions are common. And if the organization provides critical services to customers, such as a hospital or law enforcement agency, it’s smart to review the plan more often than others might.
