In foundries, continuous quality improvement through failure investigation and identification is based on the traditional failure mode and effect analysis (FMEA) using Risk priority Number (RPN). Prioritize the failure modes through RPN produces the result which does not match in practice. This research paper addresses a novel model named FEAROM to prioritize the failure modes through FMEA. The most popular technique ANOVA has been used for testing the equality of RPN values mean data through a statistical software package. An experimental study was carried out for a cast component in a steel foundry using investment casting method to validate the proposed model. It has been found that application of the proposed FEAROM model resulted in sound castings.
