FMEA RPN Corrective Action Plan

Where will you start implementing corrective actions. Meaning
will you choose a characteristic with a RPN number greater than say 200 and above and take corrective actions or where to start. I know there are customers and auditors asking to start corrective actions for characteristics with RPN number greater than 50. My opinion is that start with may be 250 or three hundred and implement corrective actions review your FMEA and go down in RPN number. I think this is a cyclic process.
Please give your opinion on this.
thanks

You need to consider all severities rated as 9 - 10 as a matter of course, so as t minimise the RPN on these failure modes. It si impossible to set a figure without knowing your rating values so I woudl suggest address the upper quartile of RPN's?
