What is a DFMEA?

A DFMEA per the AIAG/VDA FMEA Handbook begins with the Five Ts, consisting of determining the intent of the DFMEA, establishing the timing for the DFMEA, identifying team members, determining which tasks will be performed, and identifying which tool or software program will be used.

How do I identify DFMEA projects?

DFMEA Project identification includes a clear understanding of what needs to be evaluated. This involves a decision-making process to define the DFMEAs that are needed for a customer program. What to exclude can be just as important as what to include in the analysis. Below are some basic questions that help identify DFMEA projects.

What are block/boundary diagrams in DFMEA?

In the context of the DFMEA, Block/boundary Diagrams define the analysis scope and responsibility and provides guidelines for structured brainstorming. The scope of analysis is defined by the boundaries of the system; however. interfaces with external factors/systems are to be addressed.

What is the function analysis section of the DFMEA form?

The function analysis section of the DFMEA form is depicted in Figure 5. To assist with identifying functions, the new standard offers a P-diagram (parameter diagram), which graphically depicts inputs and outputs, control factors, error states, and noise factors (Yang and Basem 2009).

How does FMEA work?

When carrying out the FMEA, experts identify failures throughout the process chain and then try to graphically depict their CERs, which ultimately results in the failure net. After that, experts need to conduct the actual rating of the identified failure CERs in terms of their severity, probability of occurrence and detectability.

What is the difference between DFMEA and PFMEA?

DFMEA aims at analyzing the product design itself in terms of quality-critical aspects, while PFMEA was developed to investigate manufacturing or assembly processes and the potential failure CERs involved in these .
