DFMEA Overview A DFMEA is accessed via the eBOM\mBOM tree and is defined for a component (End Item, Assembly, Manufactured Item, Purchased Item, Feature and Item).
FMEA Structure
Functionalities
RPN
Description The user is allowed to enter description for each of the nodes in the FMEA except for the root node. Further, when a ‘Cause of Failure’ node is selected, the user is presented with a Cause, Design Control (Prevention and Detection), Recommended Action, and Action Taken list below. Different descriptions can be entered for each of the above.
Header Information Every FMEA has header information, which can be edited by selecting any of the FMEA nodes (when in edit mode). Note: The header information remains the same irrespective of the node that the user has selected.
Overview 1. Select a Component in the eBOM\mBOM Tree & go to the DFMEA tab. 2. Hit the edit button. 3. Edit information for ‘Responsibility,’ ‘Prepared By,’ ‘Core Team,’ and the Date fields. 4. To edit the information for the Target Completion Date and Responsibility (Cause) fields, the Cause node (or its children) should be selected.Edit information for ‘Responsibility,’ ‘Prepared By,’ ‘Core Team,’ and the Date fields. 5. Click on the save button and then on the “Ok” button to save all the changes.
Adding , Renaming & Deleting Functions 1. Click on the FMEA (Root Node) for a Component. 2. Hit the Edit Button & right click on the selected node. 3. Select ‘Add Function’ and a new tree node called ‘New Function’ is added. 4. Click on the ‘new function’ node, and click it again to edit it. 5. To rename a node, Right click on it and hit rename.Change the name and press enter. 6. To delete a node, Right click on it & hit delete. Select yes at the Confirmation screen.
Adding , Renaming & Deleting Failure Modes 1. Add a function for the FMEA for a Component 2. Right click on this new function. The Context menu should show ‘Add Failure Mode’ and ‘Delete’ 3. Select Add Failure Mode. A new tree node called ‘New Failure Mode’ is added. 4. Click on the ‘New Failure Mode’ node, and click it again to edit it. 5. To rename a node , Right click on it and hit rename.Change the name and press enter. 6. To delete a node, Right click on it & hit delete. Select yes at the Confirmation screen.
Adding , Renaming & Deleting Effect of Failure 1. Add a function & failure mode for the FMEA for a Component. 2. Right click on this new failure mode. Context menu should show ‘Add Effect of Failure’ and ‘Delete’. 3. Select it and a new tree node called ‘New Effect of Failure’ is added. 4. To rename a node, Right click on it and hit rename. Change the name and press enter. 5. To delete a node, Right click on it & hit delete. Select yes at the Confirmation screen. 6. Click on the RPN tab, the user can now assign a severity value to effect
Values for Severity Proplanner provides a standard set of values for severity.
Adding , Renaming & Deleting Causes of Failure 1. Add a function, failure mode, and effect of failure to the FMEA for a Component. 2. Right click on the ‘Effect of Failure. 3. Select ‘Add Cause of Failure’ and a new tree node called ‘New Cause of Failure’ is added. 4. To rename a node, Right click on it and hit rename. Change the name and press enter. 5. To delete a node, Right click on it & hit delete. Select yes at the Confirmation screen. 6. Click on the RPN tab, the user can now assign an occurrence frequency for that cause.
Values for Occurrence Proplanner provides a standard set of values for occurrence similar to the severity table.
Adding, Renaming& Deleting Design Control 1. Once the user has added a cause, Design Control (Prevention), Design Control (Detection), Recommended Control, and Action Control are automatically added. 2. Click on Design control and type in the description for the same. 3. To rename a node, Right click on it and hit rename. Change the name and press enter. 4. To delete a node, Right click on it & hit delete. Select yes at the Confirmation screen. 5. Click on the RPN tab, the user can now assign a detection value for that control. 6. After adding the detection value an initial RPN is calculated and displayed in the RPN text box under “Before”. Note: RPN or the Risk Priority Number is a product of the Severity, Occurrence and Detection values Values for Detection Proplanner provides a standard set of values for detection similar to the severity and occurrence tables.
After Analysis 1. The final step in FMEA is the After Analysis. This is done by defining the recommended action and the action taken. 2. Once the user has defined the design control, the user should click on Recommended Action, and Action Taken. 3. The user can assign new severity, occurrence and detection values for these changes; this is done in the after section of the RPN tab. 4. The rating tables are the same for both after and before, the objective is to lower the RPN in the after analysis. 5. Hit the save button and OK to save all the changes.
DFMEA Report To generate a report, select the DFMEA Report from the Report Menu. A printout of the report can be taken.
Compiled DFMEA Report A compiled DFMEA report is a roll up of all the FMEA's under the End Item or Assembly.
Sorting DFMEA report Proplanner 2.7 now allows you to sort your DFMEA report (either compiled or not) by a variety of ways. When you click on Reports command, the menu in Figure 5 will appear.
Instead of just being able to sort based on the RPN value ( Severity X Occurrence X Detection) you can now choose which values to sort by. For instance, if you would prefer to sort by the Severity value, just un-check the boxes next to Occurrence and Detection. The sort feature also gives you the option to sort based on values before or after actions and in either ascending or descending order.
