Consequence Evaluation Records

Consequence Evaluation records are used to determine the consequence of failure while performing an RBI analysis. This topic provides an alphabetical list and description of the fields that exist for the RBI Consequence Evaluation family, whose records store information that is used to determine the probability and cost of failure. The information in the table reflects the baseline state and behavior of these fields.

The following families are enabled for site filtering, which means that the records in these families can be assigned to a specific site, and will then only be accessible to users who are assigned to the same site and have the appropriate license and family privileges. See the Site Filtering section of the documentation for more information on using this feature.
