Failures (Functional Failures)

In an FMEA or RCM, the failures, (typically called functional failures in RCM analysis), state the manner in which the item or operation fails to meet or deliver the intended function and its requirements.

To access the commands to add or edit failure records, right-click inside the FMEA hierarchy or worksheet, or use the Failures commands on the FMEA tab of the ribbon. (See FMEA Tab for a complete list.)

The properties enabled (and their display names) will depend on the interface style for the current project. To view or change these settings, choose Project > Management > Configurable Settings > Interface Style.

Note: The Mechanism of Failure field is available for both Failure records and Cause records. You can use the project's interface style to enable the field for either record type.

Note the following:

The Description is required.

The Name will be used in locations where the full description would be too long to display (e.g., diagrams).

If the field contains an asterisk (*) or is blank when you save the record, the software automatically uses the first 50 characters of the full description.

The #, ID, Source Record, Associated Records, History and ribbon commands are similar for any FMEA record type. (See FMEA Records.)

The Failure Probability and Severity Class fields are used in criticality analysis and will only be available if they are enabled on the FMEA > Criticality page of the project's interface style. Note that the application will not fully validate these factors until you perform the criticality analysis.

Tip: If you need to define the reliability/maintainability characteristics for this record, use the FMRA tab. These characteristics will be applicable if you wish to perform criticality analysis, use the FMEA occurrence ratings to calculate a preliminary baseline estimate of the system reliability, share system configuration/reliability data between RCM++/RBI and BlockSim or perform RCM cost/availability calculations.
