RPNs aside for the moment, who should lead? What is your definition of lead? I look at this as someone with familiarity with the FMEA process, who knows the correct people to get involved (it is supposed to be a multifunctional activity, no?), and how to facilitate getting the job done, on track, on time, without a lot of side excursions into non-related topics. If that is you, so be it. Nobody says the leader has to be the one to come up with the information.
