Failure Modes and Effects Analysis (FMEA)

The main output from TeamSET is a printed chart in a format developed by the FMEA teams at Chrysler, Ford, and General Motors, working under the auspices of the Automotive Division of the American Society for Quality Control (ASQC) and the Automotive Industry Action Group (AIAG). This format is not ideal for display on a computer screen, so in TeamSET it is split into two separate screens for data entry.

The first screen diplays the structured parts list from DFA, and is used to enter:

• A functional description of each part
• The potential failure modes for the part
• The effects of those potential failures
• An assessment of the severity of the effect
• All the possible causes for each failure mode

To simplify the input of data, user populated libraries are available for each of the text fields. These are available as pop-up lists, accessed by a single mouse click in the appropriate field, as shown on the screen image below (click on a blank area of the image to return to the original). Alternatively the appropriate text can be typed directly into the field if its inclusion in the library is not appropriate.

Clicking on the 'Analyze' button takes you on to the second screen

This screen is used to enter:

• Design controls
• Occurrence values
• Detection values
• Recommended actions
• Details of actions taken. This field defaults to a copy of the Recommended Actions, but may be edited if required.

The values for the numerical fields (severity, occurrence and detection) may be typed directly or selected from pop-up lists. The descriptions in the lists are based on the motor industry standards, but may be changed by the user to satisfy different industry requirements.

RPN

Reports

• Summary information showing how much of the FMEA analysis has been completed, how many RPN's and other values are above defined limits, and how many actions are outstanding and/or overdue.
• Failures listed in RPN order, from the highest down to a specified lower limit, for the whole product. This enables the project manager to see at a glance the highest risk areas in the product.
• Action lists for each individual or department named in the FMEA sheets.
