(ahem, slightly OT, sorry Rosemary)
Hi redfox,
Sorry, I probably phrased my previous post poorly.
Your risk assessment (RA) is being basically assessed for defects in 2 categories - safety and non-safety (“quality”).
IMO, ignoring legality aspects, from a FS POV, risks relating to safety factors are relatively of more importance than those relating to quality. (I hope BRC will agree despite their due diligence side-additions).
Accordingly, if one wishes to directly combine (ie add together) the risks from these 2 different categories so as to obtain a single score, it is statistically questionable whether an identical scoring scale is appropriate for both categories of defect.
In practice, the use of 2 identical scales can be applied but is then typically “adjusted” in more sophisticated RAs by using a “correction factor”. For example, in a simple format, if S is the required combined score of defects in the 2 categories –
S = (sum of scores of individual safety factors).(a1) + (sum of scores of individual non-safety factors).(a2)
Where a1, a2 are the “correction factors”.
Regardless, I daresay most (all?) FS auditors will be unaware (or uninterested) in such distinctions.
@Rosemary - IMO yr basic approach (Post 4) is not unreasonable but I do suggest you hv a look at some almost equally simple but perhaps slightly more elegant (no offence intended) BRC7 equivalents, eg this thread maybe posts 8,35 inter alia -
