Configure Projects for RPN Metrics
There are two minimum requirements to configure a project to use RPNs or related metrics for risk assessment and prioritization. In a secure database, these tasks can be performed only by a user with the "Edit project properties" permission for the project.
- Select or create the appropriate severity, occurrence and detection rating scales.
- Enable at least one of the metrics in the project’s interface style.
If you want to use the customizable Risk Ranking logic in the FMEA, system hierarchy or risk matrix, you will also need to define the logic in the project's interface style. (See Risk Ranking Logic.)
Select or Create Rating Scales
The default library shipped with XFMEA/RCM++ provides a variety of rating scales that have been published in the literature and popular FMEA standards. You can customize any of these scales or create your own.
To view, edit or select the rating scales for the current project, choose Project > Management > Edit Project Properties.
On the Configurable Settings tab, the FMEA Scales (Severity, Occurrence, Detection) are used for FMEA RPN metrics and item risk; the Criticality Scales (Severity Class, Failure Prob) are used for criticality analysis; and the MSR RPN Scales (Severity after MSR, Frequency, Monitoring) are used for Supplemental FMEA for Monitoring and System Response (FMEA-MSR).
Enable Metric(s) in the Interface Style
To enable the applicable RPN metrics for the project, choose Project > Management > Configurable Settings > Interface Style.
For FMEA metrics (calculated for the failure cause), use the table on the FMEAs > RPNs page of the interface style. For Item Risk metrics (calculated for items in the system hierarchy), use the Item > Properties page.
