Add the probable causes by creating the defects that cause the problem

You must add the defects that define why the problem occurred. For each defect, you can create a chain of defects that describes why the earlier defect occurred. You add the primary defects for each reason. Then, you must add secondary and tertiary defects that describe what caused the primary defects.

For example, if the Problem Solving process is created to resolve the problem of the car wiper not working, you must add the defects that describe why the car wiper is not working. The following might be possible reasons:

• The wiper blade is not working properly

• The wiper blade is not fixed properly on the wiper arm

• The width of the wiper blade is not proportionate to the wiper arm

• The dimensions of wiper blade and wiper arm are not considered during Design Failure Modes and Effects Analysis (D-FMEA).

Procedure

1. From Launcher, click Changes .

If this option is unavailable, search for it. You can pin it from the search results for future access.

2. From the CHANGES folder, select and open the Problem Solving process that you want to edit.

3. Click the Root Cause Analysis work mode.

Note You must have already created the problem description defect before creating the defect.

4. In the left pane of the Root Cause Analysis work mode, select the defect where you want to add the new defect, and do the following:

Choose More Commands

New Defect.

You can also right-click the defect, and choose Defect.

In the Root Cause Analysis Tree panel, select the defect and click Defect in the work area toolbar. You can open this panel by choosing More Commands

View  > Show RCA Tree . This panel can be opened from all Problem Solving tabs, except the Root Cause Analysis work mode. The panel displays the entire Root Cause Analysis tree structure containing the problem description defect and its child defects, 5Whys, and Ishikawas that you have added. You can also open the linked failures and defective items from the Related Failure and Defective Item columns, respectively. The panel allows you to retain the context of root cause analysis while navigating to different locations in Teamcenter.

Specify a name for the defect and optionally, enter a description.

Siemens Industry Software Inc. recommends that you do not use the following characters to avoid errors:

Single quotation mark (')

Double quotation mark (“)

Note If Teamcenter Copilot Quality is available, you can prompt it to create suggestions for your quality data.

From the Analysis Dimension list, select the dimension of the analysis being done in the defect:

Occurrence: Select this option to identify why the problem occurred.

Non-Detection: Select this option to identify why the problem was not detected earlier.

From the Analysis Type list, select the type of analysis that you want to perform:

Specific: Select this option to identify why the specific problem occurred.

Detection: Select this option to identify why the problem was not detected earlier.

Systemic: Select this option to identify why the system allowed the problem to occur.

(Optional) Select the Reoccurring check box if the defect is a reoccurring defect.

(Optional) Specify the Category of the defect.

Add the required failure.

Click Add.

The defect is added under the defect selected in the left pane.

Add the required defective item.

Repeat the steps until you have added all the required defects.
