The pandemic has increased organizations’ interest in business continuity, as a way to protect themselves against disruption of their operations. However, in most cases, there is no time to wait for learning about business continuity processes, policies, procedures, and terms.

Now, think about how fast after a disaster you want your business to resume operations – this is the Return Time Objective (RTO). In recent days, the term MTPD (Maximum Tolerable Period of Disruption) is replacing the use of MAO (both terms have the same meaning).
