Managing the Control Plan
Compare and align updates between the source FMEA and generated
target Control Plan
After you generate a Control Plan from an FMEA, you might make updates to the source FMEA and the target Control Plan. To ensure that the target Control Plan and the source FMEA contain the latest data, you must compare and align the updates between them.
Some of the updates in the source FMEA can be:
Adding new system elements, functions, or Quality Characteristics
Editing existing FMEA properties, system elements, functions, or Quality Characteristics
Removing system elements, functions, or Quality Characteristics
Some of the updates in the target Control Plan can be:
Adding Inspection Definitions, Quality Characteristics, or reference objects
Editing Inspection Definitions, Quality Characteristics, or reference objects
Removing Inspection Definitions, Quality Characteristics, or reference objects
You can generate a summary of the differences between the source FMEA and the target Control Plan. You can review each difference, and then you can choose to align the update ensuring that the source FMEA and the target Control Plan contain the latest data.
Example
If you add an Inspection Definition to a function in the source FMEA, the summary notifies you that the Inspection Definition is missing in the target Control Plan. If you update an Inspection Definition in the Control Plan, the summary notifies you that the Inspection Definition exists only in the target Control Plan.
If the source FMEA is generated from an existing bill of materials (BOM) or bill of processes (BOP), the part from the product structure is added to the Inspection Definition as a reference in the FMEA. When you generate a Control Plan from this FMEA, the part is added to the Control Plan’s Inspection Definition as a reference. If you remove the part from the Control Plan’s Inspection Definition, you can add the part back to the Control Plan. To do this, generate a summary of the differences between the source FMEA and the target Control Plan, select the Inspection Definition where the reference object is modified, and align the difference.
Procedure
In the folder where you created the Control Plan, select and open the Control Plan that you want to compare and align with the source FMEA.
In the Overview, select the source FMEA in the Source FMEA section, and click Generate Difference Summary in the work area toolbar.
A notification is displayed in the Alerts panel when a summary of the differences is generated. Note The administrator must have started the Dispatcher services to generate a summary of the differences.
- To view the summary, click Alerts and click the generated summary in the Target Object section.
To view the summary, you can also click Show Difference Summary in the work area toolbar.
- Expand the summary to view the list of differences.The source FMEA and target Control Plan information is displayed, and you can compare and perform the alignment.
Example Exist only in Target indicates that the update is available only in the target Control Plan. In the example, an Inspection Definition is added in the target Control Plan, and it is indicated by Exist only in Target. Missing in Target indicates that the update is available only in the source FMEA. In the example, a function was added in the source FMEA, and it is indicated by Missing in Target.
- Select a difference to be updated in the target Control Plan, and click Align in the work area toolbar.
The target Control Plan is updated from the source FMEA as follows:
If the update is Missing in Target, then the update is added to the target Control Plan.
If the update is Exist only in Target, then the update is removed from the target Control Plan.
If the update is Structure Modified, then no updates are made to the target Control Plan.
A notification is displayed in the Alerts panel when the update is done. Note The administrator must have the Dispatcher services running to update the target Control Plan.
- Click Alerts to view the details of the alignment update. You can also download the logs of the alignment update from the Target Object section.
