Navistar Case Study

Integration of ReliaSoft XFMEA into Navistar’s Reliability Functional Excellence

Navistar has been on the Reliability Functional Excellence (RFE) journey for the past two years. RFE is centered around delivering an integrated end to end to support and enhance product development, launch and life cycle management. The first step in our RFE process was to strengthen our risk evaluation process. At the beginning of every new vehicle development program, a collection of new DFMEAs would be either be developed from scratch or existing DFMEAs would be located as a baseline and then modified for the specific program. Developing new DFMEAs for every program which was challenging with aggressive timelines and was not an effective solution to capturing previous knowledge. Selecting existing DFMEAs was also not optimum as the DFMEA quality was inconsistent as there was no defined approval or configuration control process. Additional time was required to clean up DFMEAs or worse, poor DFMEAs were used.
