The scale is intended to be logarithmic, similar to the moment magnitude scale that is used to describe the comparative magnitude of earthquakes. Each increasing level represents an accident approximately ten times as severe as the previous level. Compared to earthquakes, where the event intensity can be quantitatively evaluated, the level of severity of a man-made disaster, such as a nuclear. Oct 25, 2019 Crash data was extracted from the Critical Analysis Reporting Environment (CARE) package from 2005 to 2015. Crashes that occurred one mile beyond the end of the downgrade were included with crashes within the downgrade section as recommended by the Grade Severity Rating System (GSRS) Users’ Manual.
...A couple of years ago we reviewed our Severity Occurence Detection Ranking.
A broad difference existed in using scales of 1 to 10.
As a improvement the scales were refined to 1 to 5.
Thus I have a Max RPN of 125.
This has worked fine and provides good repeatability of classification for different users and team members...

Severity Rating Scale
Out of curiosity and because it isn't clear from your initial post, are your criteria equivalent to the full range of the ratings suggested in the FMEA manual? Or do your criteria not use the full range, on the basis that your products would never use the higher values?Microsoft Severity Rating System
Re-worded: Are your '5' ratings the same description as '10' in the FMEA manual or are your '5' ratings the same as the '5' in the manual?
