About What-If Analysis

A What-If Analysis is a child analysis of a main RBI Analysis that allows you to calculate the risk associated with an RBI Component under hypothetical circumstances.

What-If Analyses allow you to analyze hypothetical situations to determine how operational and procedural changes would impact the risk associated with a subcomponent's failure on a certain date.

In baseline Risk Based Inspection:

The What-If Analysis is linked to the main RBI Analysis through the Has RBI Analysis relationship.
When you create a What-If Analysis, Meridium Enterprise APM copies the values from the records in the main RBI Analysis to new records in the child analysis.
The Analysis ID matches the Analysis ID of the main RBI Analysis.
The field values in the What-If Analysis match the field values in the main RBI Analysis. However, the following fields are not copied:
