Failure Effects, Failure Modes, and Harm Hazards
You can create lists of failure effects, failure modes, and harm hazards to be associated with various parts in your system. This association allows you to see the impact a particular type of failure would have, or to see what parts could contribute to a specific effect.
• A failure effect occurs after a part fails. For example, one part in a computer monitor is a capacitor. If the capacitor fails open, the effect might be that the monitor displays wavy lines. If the capacitor fails short, the monitor might go blank. Failure effects depend on the type of failure, called the failure mode.
• A failure mode is a way that a part can fail. For example, one part in a computer monitor is a capacitor. A capacitor can fail open or fail short, which is the failure mode. Failure modes impact the ways a part can fail, and these impacts are called failure effects.
• Hazards are potential sources of harm, such as energy hazards, chemical hazards, biological hazards, operational hazards, and informational hazards. Harm occurs when people are injured physically, when their health is compromised, or when property or the environment is damaged.

As a best practice, use types to create failure effects and failure modes, rather than creating many objects to cover different classes of failure objects.
To show these objects in your quality context, set the Allow Failure Modes, Effects and Harm Hazard preference to Yes.

Importing from a Spreadsheet
You can import information for failure effects, failure modes, and harm hazards from a spreadsheet.
|
|
Non-integer values on import are rounded to integer values.
|
• To determine the quality container in which failure mode, failure effect, and harm hazard objects are created, use the Quality Container for FMEA Import from Spreadsheet preference. Add the name of the quality container in the Value field.
• To view the FMEA table that holds the imported spreadsheets, on the information page for the part, click a new tab. Click > > .
• To import information, do the following:
1. Click the initialize import job icon
. The
Import from Spreadsheet window appears.
2. Browse to the file.
3. From the Import Action list, select either ADD AND UPDATE or ADD ONLY. The other options are not supported.
4. Click Validate Spreadsheet.
▪ If the validation is successful, the “Validation Succeeded” message appears.
▪ If errors appear in the Errors and Warnings table, do the following:
1. Review the messages in the Errors and Warnings table.
2. Update the spreadsheet as needed.
3. Save the spreadsheet.
4. Browse to the spreadsheet and click Validate Spreadsheet.
5. Click Finish.
