Subject: Examples for Comparison
Has anyone out there compared the results from projects you've done WITHOUT using reliability software to ones that you HAVE used PRISM on? I'd like to take a system that was analyzed without PRISM and compare the failure rates with what PRISM predicts. If anyone has a sample system that I could create in PRISM, please contact me so that we could exchange information and results. Thank you for your help.

TRW Automotive (formerly TRW Chassis System Division) in Detroit, MI recently completed a 10 month in-house effort to identify improved methodologies for assessing reliability and determining warranty costs. The results of this study were published in the first quarter 2002 RAC Journal . The study consisted of acquiring a thorough understanding of the methodology itself, conducting a PRISM assessment on a system with demonstrated performance, and critically analyzing the PRISM results, including predicted vs. actual failure rates and predicted high failure rate contributors. Results of the effort were positive, with TRW training a team of internal PRISM experts and adopting PRISM methodology as a starting point in a comprehensive methodology to cover a wide range of electro-mechanical systems.
