Managing Computation Rules
Computation rules are defined to compute the BIA results.
They help implement the algorithm that computes:
• the RTO (Recovery Time Objective)
The Recovery Time Objective (RTO) determines the maximum tolerable amount of time it takes to bring critical systems back online, possibly in a Degraded Mode. It is related to downtime, representing target time following an incident for Product or service delivery resumption, or Activity resumption, or Resources recovery.• the business impact
Listing Computation Rules
To access computation rules used within a Business Impact Analysis:
In the navigation bar, select Administration > Business Continuity > Computation Rules.Computation rules are of several types and can be accessed via a drop-down list:
Computation Rule Types
A computation rule is supplied by default within each category.
You may create your own rules within each category. Answer score computation rule
This rule is used to compute the score of each impact type within a Business Impact Analysis (BIA).
Impact type computed value =
Weight of the impact type * Weight of the impact type value * Weight of the downtime period
RTO computation rule
This rule is used to compute the RTO (Recovery Time Objective) within the framework of a BIA.
Business impact computation rule
This rule is used to compute business impact within the framework of a BIA.
