...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...

Microsoft Severity Rating System
Pavement Condition Rating Procedures and Indices (March 27, 2003) Equipment Mn/DOT currently collects pavement condition data using a Pathway Services, Inc. Video Inspection Vehicle (VIV) as shown in Figure 1. There are five lasers mounted across the front bumper, one in each wheel path, one in the center, and two outside each wheel path. The PACP Quick Rating is a shorthand way of exppgressing the number of occurrences for the two highest severity grades in a specific segment 1.The first character is the highest severity grade occurring along the pipe segment. 2.The second character is the total number of occurrences of the highest severity grade. After 9 a letter code isused. The first system was developed by the Bureau of Public Roads (BPR) before 1960. This system posted arbitrary ratings for downhill slopes as warnings about the severity of descent for road users (Hykes, 1963). The BPR rating system was developed by surveying grades and placing them in three categories:.
Generally this short hand form of risk rating is used to determine which hazard should take priority over another in terms of deciding what to do and when. To calculate a Quantative Risk Rating, begin by allocating a number to the Likelihood of the risk arising and Severity of Injury and then multiply the Likelihood by the Severity to arrive at the Rating. The number to be allocated is set out. The CDR® Dementia Staging Instrument in one aspect is a 5-point scale used to characterize six domains of cognitive and functional performance applicable to Alzheimer disease and related dementias: Memory, Orientation, Judgment & Problem Solving, Community Affairs, Home & Hobbies, and Personal Care.
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?
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?
