{{Template:BL-OR-5 banner}}


'''Impact Tolerance''':

'''''Notes (1):''''' represents the point beyond which the [[Levels of Harm|harm]] caused by an operational disruption to the business service becomes intolerable.

'''''Notes (2):''''' do not factor in the frequency at which operational disruptions are likely to occur.

'''''Notes (3):''''' focus on limiting the impact the organisation can tolerate from a single disruption.

'''''Notes (4):''''' is different from the [[Recovery Time Objective (RTO)| recovery time objective]], and the maximum acceptable outage as defined in [[Business Continuity Planning (BCP)| business continuity planning]] as these are time-based.

'''''Notes (5):''''' focus on outcome-based objectives: how much, when, and for how long.

'''''Notes (6):''''' should relate to a single disruption as the concept is designed to identify how quickly an organisation can restore delivery of important or critical business service after an operational disruption.

'''''Notes (7):''''' in another view by the Monetary Authority of Singapore is the [[Service Recovery Time Objective]] (SRTO) which is the target duration of time to restore a specific business service from the point of disruption to the point when the specific business service is recovered to a level sufficient to meet business obligations.

'''''Notes (8):''''' should not set at excessively high levels.  Regulatory authorities will perceive that this organisation is  
able to manage its service continuity for all scenarios without any investment.

== '''''Impact Tolerance Versus [[Recovery Time Objective]]''''' ==

'''''Notes (1):''''' Impact Tolerances are expressed by reference to specific outcomes and metrics and differ from the recovery time objective (RTO) and the [[Maximum Acceptable Outage (MAO)| maximum acceptable outage]] as defined in business continuity planning, as these are time-based.
