Managing Computation Rules
To access computation rules used within a Business Impact Analysis:
*In the navigation menu, select Administration > Business Continuity > Computation Rules.
Computation rules help implement the algorithm that computes:
the RTO (Recovery Time Objective) 
the business impact
Computation rules are of several types and can be accessed via a drop-down list:
Answer score computation rule
RTO computation rule
Business impact computation rule
*Colors used to display the global business impact are defined here.
You may create your own rules within each category. A computation rule is supplied by default within each category.
Answer score computation rule
This rule is used to compute the score of each answer within a Business Impact Analysis (BIA).
= Weight of the impact type * Weight of the impact type value
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.
Business Impact Values
You can specify (connect) the business impact values to be used in the computation rule.
These values are used when computing the final value of a Business Impact Analysis (BIA).
*For more details on BIA results, see View Computed Business Impact.
To define business impact values and corresponding colors:
*In the navigation menu, select Administration > Business Activity > Business Impact Values.
