Dont you think that is is not correct to go only by the RPN numbers when doing FMEA. Two problems having same RPN numberswould cost the copany 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 Infact combinations of RPN and Quality Costing would be abetter. I am right now working on combining the RPN number and concept of Quality Costing and your advice can help me in my thesis.

Thanks

There's no problem with that. You can have a line item with an RPN of 300 which would be too expensive, or it may be a technology issue, or what ever, to address beyond what you already do to control and isolate the problem line item. You do not have to operate only on the top numbers. You DO have to be ready to explain which ones you're operating on and why and why any high numbers are not being acted on. I would expect comments within the FMEA.
