Specify known fixed FR
If component or assembly failure rate is known (provided by manufacturer, by third-party database, field usage failure analysis, testing/QA failure analysis) you may specify it in the FR u (user-defined) or FR f (FR field) data fields on the item data screen. Be sure to set correct FR source switch.
To specify user-defined FR:
1. Open item data screen.
2. Set FR source switch to User-defined and specify your FR in the "FR u" field:
3. Press Ok to return to the product tree.
To specify field FR:
1. Open item data screen.
2. Set FR source switch to Field and specify your FR in the "FR f" field:
3. Press Ok to return to the product tree.
For both cases you may provide explanation about the FR source in the "Source of FR" text field.
Both Failure Rates (User-defined and field) may be imported using Import Wizard.
