Understanding Work Order Failure Tracking and Analysis
PeopleSoft Maintenance Management provides users the capability to track and analyze equipment failure incidents for various operational and regulatory needs, such as health, safety, and environmental compliance. These failure incidents are defined as failure events in a work order which are directly tied to a target asset that has failed in a work order task.
You can analyze these asset failures to:
Help prevent recurrence or minimize the number of future incidents.
Reduce associated downtime and repair costs.
Measure and track both asset reliability and maintenance and repair effectiveness.
Support repair versus replace decisions.
Support related planning and budget allocation activities for constrained maintenance resources.
To accomplish these goals, PeopleSoft Maintenance Management enables users to set up failure severity and failure impact codes to define data that describes, quantifies, and qualifies asset failure events from the various perspectives of the Work Order, Work Order Completion, or Technician Workbench components. You can analyze failure events based on specific detail or summary criteria in Failure Analysis inquiry, where you can discover trends and relationships affecting future failure occurrence, asset reliability, and maintenance and repair effectiveness measures. Failure tracking and analysis are optional activities that can assist supervisors and managers to carefully manage their assets.
You define failure severity and failure impact codes based on the requirements of your organization. When you perform a failure analysis, you can select failure severity and failure impact codes to search for specific failure events to analyze on the Failure Analysis page. PeopleSoft Maintenance Management delivers sample data that contains examples of these two types of failure codes. You can use this sample data to help you define your own failure codes.
You must set up failure severity codes for your organization before you can track failure events in PeopleSoft Maintenance Management. Each code describes the seriousness of the asset failure to your organization. For example, you could define failure severity codes as critical, high, medium, low, or none or with numerical values. You are required to select a failure severity code on the Work Order Failure Tracking page.
Failure impact codes are useful for identifying how the failure of an asset will affect specific organization circumstances or requirements such as hazardous conditions or materials, health issues, safety issues, and more. You can assign more than one failure impact code to a failure event on the Work Order Failure Tracking page. However, you are not required to set up or use failure impact codes to complete the Work Order Failure Tracking page.
Once the failure impact and severity codes are established, you can enter, maintain and review the data associated with an asset failure event in the Work Order Failure Tracking component. You can create a failure event directly from the Work Order, the Work Order Completion, and the Technician Workbench components. A failure event is defined based on the failure or problems of an asset selected for a work order task. While tracking failure events is an optional activity and is only appropriate for certain critical assets or classes of assets within an organization, defining failure events will enable your organization to obtain additional information that quantifies and qualifies the nature of an asset's failure.
When you create a failure event from the Work Order, the Work Order Completion, or the Technician Workbench components, the system automatically assigns the next Failure ID in the system to the failure event. You cannot override this value. When you save the Work Order Failure Tracking page, the system updates this failure ID number in the Last Failure ID field on the Definition page of the work order business unit associated with the failure event.
If you create a failure event from the Work Order Failure Tracking component, you can accept NEXT as the default for the Failure ID and the system assigns the next failure ID to the failure event. You can also override NEXT with a unique failure ID. A unique failure ID is not tracked on the Definition page of the work order business unit.
If you entered a unique failure ID for one failure event, and created the next failure event from the work order, which automatically assigns a failure ID number, when you save the Work Order Failure Tracking page, the number generated is automatically updated in the Last Failure ID field on the Definition page of the work order business unit.
In addition to failure ID, the Work Order Failure Tracking page consists of:
Information about the work order, work order task, and the asset associated with the failure event.
Problem reporting information.
Detail information describing the failure event.
Failure impact information.
Asset downtime information.
A list of causal parts.
Meter reading data.
Warranty claim information.
Much of this data is replicated form the work order task data. It appears in this component to enable you to review or update any of this data that may have a bearing on the failure event without returning to the work order. You can also this data as search values in the Failure Analysis component.
However, you can, at a minimum, log a failure event by selecting a severity code and the start date for the failure.
You can access the Work Order Failure Tracking page to update or review an existing failure event or add a new failure event from the:

The PeopleSoft Maintenance Management Failure Analysis component enables you to perform a meaningful analysis of system-calculated metrics based on the tracking of failure events associated with a work order task. You can easily search and group the asset failure event data that you want to analyze. When the system calculates the metrics and displays the data for the selected asset failure events, the resulting data may include:
Total Failure Count.
Mean Time (Days) Between Failure (MTBF).
Mean Time (Hours) to Repair (MTTR).
Mean Cost (Currency) to Repair (MCR).
Mean Reading (Meter Units) Between Failures.
To analyze one or more asset failure events, you:
Enter the search criteria for the failure event data that you want to analyze.
Select the appropriate analysis method by:
Selecting an analysis option from the available list of failure events.
The default option for a new search is Failure Event (Detail), which shows all of the failure events that match your search criteria. You can choose one of the summary options that provide different summary views of the detail failure event data.
Selecting the failure event data that you want to analyze from the search results.
Selecting the Show Totals button to display the failure event totals based on the selected analysis method.
Creating a chart based on the select data.
