Dont you think that it is not correct to go only by the RPN numbers when doing FMEA. Two problems having same RPN numbers would cost the company different amount of money in terms of rectification and lost sales....Moreover it is also possible that for one process the RPN number is low but the cost due to error would be high. In fact combinations of RPN and Quality Costing would be better. I am right now working on combining the RPN number and concept of Quality Costing and your advice can help me in my thesis.
