A work order represents one single failure occurrence (event) for the asset specified on the work order. There are three main Failure Code Types: Failure Code, Cause Code, and Resolution Code. When creating a work order, these failure codes are specified on the work order, such as Compressor Shaft Damage (Failure), Vibration (Cause), and Replacement and Re-calibration (Resolution), respectively.

User-defined Failure codes, Cause codes and Resolution codes are organized into multiple tree structures called Failure Code Sets, which are then assigned to asset groups. Each set provides asset group-specific information on the possible failures of an asset group, the possible causes of each failure, and the possible resolutions for each cause. Assets within an asset group inherit the assigned Failure Code Set. At the work order level, Failure Tracking codes are entered to report a failure, its cause, and resolution. The assigned Sets provide a disciplined methodology to collect failure data on assets. Inquiries on failure data are performed, based on user-entered criteria, such as date range, asset groups or assets, departments, or areas. Mean Time Between Failure (MTBF) and Mean Time To Repair (MTTR) are calculated with each inquiry.

   To define failure codes:

1. Navigate to the Failure Sets page (Maintenance Super User: Failure Analysis > Failure Tracking Setup).

2. Choose Define Failure Codes.

3. Select the appropriate Code Type, such as Failure Code (See: Failure Code Types).

4. Enter the Code, for example, Mechanical.

5. Enter the Code's Description, for example, Mechanical Parts Failure.

6. Optionally enter an End Date, to apply an expiration for the current code.

7. Optionally choose Save to create the codes and remain on the current page.

8. Click the Apply button to create the codes and return to the previous page.

   To define a failure set:

1. Navigate to the Failure Sets page.

2. Choose Create Failure Set.

3. Enter the Name for the failure set.

4. Optionally enter a Description for the failure set.

5. Optionally enter an End Date, to apply an expiration for the current failure set.

6. Optionally select an existing failure set from the Copy From Failure Set list of values.

   If the failure set that you are creating is similar to an existing failure set, you can copy failure codes from an existing failure set, aiding in multiple failure set entry. To copy the failure hierarchy from another failure set, you can use the Copy From Failure Set field. The list of values includes active failure sets. Click the Go button and the failure combinations of the selected failure set appear. You can delete any unwanted combinations.

7. Select a Failure code. The code's Description defaults.

8. Select a Cause code. The code's Description defaults.

9. Select a Resolution code. The code's Description defaults.

10. Optionally enter an End Date, to apply an expiration for the current group of codes.

11. Assign the current failure set to an Asset Group or Rebuildable Item.

    Asset numbers or rebuildable serial numbers within an asset group or rebuildable item, respectively, inherit the assigned Failure Code Set.

    1. Select an asset group from the list of values.

       The asset group's Description defaults from its definition.

    2. Select whether Failure Code entry is required on work orders created for assets within the current asset group.

       For example, select Yes from the Failure Code Required list of values to ensure that Failure Codes are entered when creating work orders for assets within the current asset group. The Failure Code Required value defaults to the work order, but you can optionally change it.

12. Optionally click the Save button to create the failure set and remain on the current page.

13. Click the Apply button to create the failure set and return to the previous page.
