Design Verification Plans (DVP&Rs)

Xfmea allows you to add a design verification plan and report (DVP&R) analysis for any item in the system hierarchy. A DVP&R is a worksheet that is used to track the progress of design verification tests. The lessons learned from the design FMEA can be a valuable input to the DVP&R (and vice-versa).

To add a DVP&R, select an item in the System panel then choose Insert > Other > Add DVP&R.

The DVP&R analysis tab will open in the Analysis panel. In addition, the DVP&R icon will appear in the corresponding column in the System Hierarchy tab of the System panel (if that column has been selected for display on your computer). To hide or display columns, right-click the column headers in the System panel, then click Customize Columns to select which columns you want to display. These settings are stored per computer/username in the System Hierarchy page of the Application Setup, so any project that you open on this computer will have the same columns displayed.

The DVP&R analysis contains two tabs: a Header tab and a Worksheet tab. The Header tab contains general information about the entire analysis that will be displayed in the header of the report output while the Worksheet tab contains the analysis data. A DVP&R can have zero, one or many plan records. Each plan can be associated with one or many report records. The background color in each cell of the DVP&R worksheet identifies the record type (plan = blue and report = green).

Typically, DVP&Rs are used in one of two ways:

As a stand-alone analysis. In this case, you:
- Add the DVP&R analysis.
- Define the header information on the Header tab.
- Use the Worksheet tab to record all of the test plans and reports that need to be tracked.
In tandem with a Design FMEA. In this case, you:
- Create an FMEA for the item.
- Add the DVP&R analysis to the item. Xfmea automatically transfers the controls and/or actions from the FMEA to be the starting point for the new DVP&R.
- Define the header information on the Header tab.
- Use the Worksheet tab to record all of the test plans and reports that need to be tracked. This may require that you edit or add to the data transferred from the DFMEA.
