About Evaluating Risk in an ACA

Within an ACA, you can evaluate the unmitigated risk associated with a failure of the following items:

The systems that are represented by the ACA System records that belong to the analysis.
The equipment and locations that are represented by the Equipment and Functional Location records that belong to the analysis.

To assign the unmitigated risk value to ACA System, Equipment, and Functional Location records, you can use any of the following methods:

Assign the risk values in ACA using the Risk Matrix that is configured for the site that is associated with the ACA.

-or-
Assign the risk values in ACA using fields in the ACA System record. This option will cause the Risk Matrix to be locked for the ACA System record and the individual Equipment and Functional Location records to which it is linked.

When you evaluate the unmitigated risk in ACA, a Risk Assessment record is created and linked to the corresponding record (e.g., the ACA System record).

If a Risk Assessment record is already linked to a record when it is added to the ACA, that Risk Assessment record is also added to the ACA.

Note that after you evaluate the unmitigated risk for an ACA System record, any Equipment or Functional Location records that you link to the ACA System record will inherit the unmitigated risk of that ACA System record. Also, as long as the Risk Matrix has not been locked by an administrative user, any Equipment or Functional Location records that were already linked to that ACA System record will not inherit the updated unmitigated risk. They will retain their own individual unmitigated risk. If the Risk Matrix has been locked by an administrative user, however, any Equipment or Functional Location records that were already linked to the ACA System record will continue to inherit the updated unmitigated risk.

Note: This section of the documentation assumes that a Risk Matrix has been configured by an administrative user.
