Hello everyone,

I'm having some problems understanding a non conformity we got related to the traceability process that states that we "Effectiveness is defined as 99.5 % - 105% of the target material within 4 hours"

 

How can the recovery percentage be more than a 100%?

 

Any information would really help

 

thanks in advance!

The reason is we are all human and make mistakes

 

Maybe a lot got entered as 102 cases when it was only 100 or was 105

 

Or a case got damage and was thrown out, but not removed from inventory

 

Or on paper you received 5000 units of X but in reality received 5100 units (cause no one actually counted at receiving)

 

Finished goods made-inventory should equal 100%

 

Finished goods-inventory+key stroke error = 105%

 

I add to have our software zero'd out this year----discovered it had carried over inventory since the software was installed (8 years ago) and it was telling us we didn't have something when we actually did

 

I hope that helps

Short answer... It can and cannot be more than 100%.  Traceability should be determined in the amount that can be traced, the accuracy in trace and the speed at which the trace was completed.  105% would be achievable if the inventory was not accurate to begin with and would show a whole different type of issue with the system.  You could get that if you receive more product back than you initially shipped or you misshipped different product to throw off inventory.  The target should be 100% within 4 hours.  Too much is an inventory issue, too little is a trace issue.

Hello giovsteph,

 

IMO, during recall/withdrawal, traceability is conducted to trace the source of RM and track the FG. If you have 100 bottles affected, but on your traceability you have 105 bottles to recall, it is better recalling 105 bottles than recalling 95 bottles only. Where is the 5 bottles that could affect consumers?

 

No standard are giving the quantified result of traceabiliy, what is low and what is high, what is acceptable and what is not.

 

regards,

redfox

if you have over 100% then its likely that you dont have full traceability since you have an unaccounted excess.

 

perhaps it could also be that you have obtained more information that what was actually required. hypothetically, it may be a product that increases in weight or quantity without other inputs (maybe just exposure to air makes it heavier).

When a traceability exercise isperformed, only the relevant materials are inspected and +/- 100% would be expected

 

If cartons need liners, and employees damage and throw out 20/day or 100/week or 400/month or 4800/year and you aren't aware of that your tracability on packaging would be out, but you don't know where they've gone

 

Dry ingredients could get spilled and no one weighed the spillage so it looks like you've used it but you actually haven't

 

The entire idea of the exercise is to improve!  And you cannot do that if you don't know where the issues are and you can't do that until you perform the exercise

 

Exposure to air makes it heavier?  I would hope any material that could do that (let's say flour for the sake of argument) is properly stored so that doesn't occur
