Acceptable Outage
The Impact Rating Reference is a guide for determining whether the
department can tolerate a disruption to a business activity. Assume the worst
case scenario and normal day-to-day resources are not available.
IMPACT Rating Reference
Insignificant
No measurable impact
 Minor business disruption or security threat that causes no
material disruption to departmental services
 No impact on stakeholders
 Incident absorbed by routine management
Minor
 Localised business disruption or security incident
No slowing of business.
Only a small distraction
 Readily contained and absorbed through local unit
management intervention in contingency mode
Moderate
 Moderate business disruption or security incident resulting in
disruption to some of the department’s critical services
Will require action but
business is still largely
on track
 Some inconvenience to stakeholders
Major
 Significant business disruption or security incident resulting
in prolonged disruption to critical services across the
department
Will cause disruption
and require more
resources/time or will
reduce quality
Critical
Will stop key business
deliverable or process
and prevent
achievement of
objectives
 Minimal impact to stakeholders
 Cross management intervention is required and effort in
contingency mode
 Considerable impacts to stakeholders
 Substantial senior executive intervention is required and
effort in contingency mode
 Extreme business disruption or security incident resulting in
indeterminate prolonged suspension of critical services
across the department
 Debilitating impact on stakeholders
 Immediate senior executive and/or ministerial intervention is
required
 May require external assistance
Business activities with a ‘Major’ or ‘Critical’ impact rating will then sorted by
the length of time the department is prepared to operate without that activity.

Maximum
Acceptable Outage
Time
The maximum TIME a business activity can be disrupted before the disruption
is unacceptable to the department is categorised in the following intervals:

1 – 2 business days

3 – 5 business days

6 – 15 business days

More than 16 business days
These time intervals are called the Maximum Acceptable Outage (MAO).
Critical business activity
Delivering essential services in a disruptive event relies on quickly resuming
critical business activities within the maximum acceptable outage timeframe.
A Critical Business Activity
is any activity identified as having
a ‘MAJOR’ or ‘CRITICAL’
impact rating
and
a maximum acceptable outage
(MAO) time of
15 BUSINESS DAYS
OR LESS
All critical business activities are captured in a Business Continuity Plan.
NOTES:

When deciding on an appropriate MAO for a business activity, consider any interdependencies
and how their respective MAO rating may impact (see ‘Interdependencies’ factsheet).

Business activities may only be ‘critical’ during a specific time of year or circumstances.
