The Risk Priority Code (RPC) was used to prioritize failure modes, when two or more failure modes have the same RPN. They proposed a new method to prioritize failure modes, when there is a disagreement in ranking scale for severity,
occurrence and detection.
An Analysis of Variance (ANOVA) was used to compare means of RPN values.
SPSS(Statistical Package for the Social Sciences) statistical analysis package is used to analyse the data.
The results presented by them are based on two case studies.
It was found that the proposed new methodology/approach resolves the limitations of traditional FMEA approach.
FMEA does not attempt to give comprehensive answers to the frequently answered questions (FAQs), which are addressed in the main document.
