Why the updated QI?
Suppliers will not be scored until they have delivered a minimum of 50 batches. Suppliers who deliver less than 50 batches in 62 weeks will not be scored. This concerns approximately 0.2% of the batches offered.
- Class A: more than 98.5% of batches without deviation
- Class "B": 98.5% to 94.5%
- Class "C": <94.5%
- No score: if fewer than 50 batches have been supplied
Exactly how is the updated QI calculated?
- Formula: QI = (# lots - # lots with erroneous information) / (# lots)%.
- This concerns erroneous supply information for the fields product code, sorting code, inspection code and misleading photos.
- The period over which QI is determined is 62 weeks. Lots and claims observed before that term, e.g. 70 weeks will not be counted.
- Daily determination of QI (after completion of complaints procedure).
- 1 lot equals a maximum of 1 QI error.
- QI at company level.
- A grower has to have supplied at least 50 lots in 62 weeks.
- The QI is only calculated for auction supply.
In the formula: QI = (1,000 - (5 claims +2 observations))/1,000 = 99.3%
In words: The grower supplied 1,000 lots for which there were 6 claims pertaining to 5 separate lots. This therefore adds up to 5 errors. We adjusted 2 lots for auction and these also count. Thus, this ultimately means that 993 of the 1,000 lots were error free, that is 99.3%.
This grower therefore scores in class "A".
Grower B supplies one location. The grower supplies seasonal products and supplied 200 lots in 4 weeks. 2 claims came in regarding 5 separate lots and 3 adjustments were made.
But 56 weeks prior the grower had also supplied: 200 lots with 4 claims. These fall within the 62 weeks so will also be counted: QI = (400 - 9)/400 = 97.75%.
This grower therefore scores in class "B".
