I have been tasked with reviewing and analyzing our corrective actions and root causes. One of my thoughts is to develop "categories" the "wordy" root causes can be fit into. Examples: Failure Mode not defined on PFMEA Failure Mode defined on PFMEA - Inadequate Controls I would like to come up with a list of 10 or so categories so moving forward we can assign them to one category. We would then be able to more effectively determine where our system is weak and where to best allocate resources. Does this approach make sense? if so, what other categories could be added?
