Application of DFMEA to Real-Life Example

This chapter provides a case study of a Design Failure Modes and Effects Analysis (DFMEA) for an actual telecommunications project. As a result of conducting this DFMEA, design faults were identified that otherwise may not have been discovered. Design changes were introduced to prevent these faults from being discovered after product introduction. Using the initial and revised RPNs, the design improvements can be quantified. The lessons learned from this project were identified and used to improve the effectiveness and efficiency of the subsequent DFMEAs for this project.
