Review sample of 2,000 cards
Unknown values go to a separate list
Challenge
The store was merging catalogs from several suppliers. Identical products landed in different categories, and material, colour and size values were written in different formats. Before loading into the updated catalog, the cards had to be brought into a single structure.
Solution
HUBBLE GROUP mapped supplier categories to the client's classifier and prepared rules for filling the mandatory attributes. On a pilot batch of 500 cards the team agreed the disputed cases and the acceptance criteria.
After the main set was processed, cards with missing or contradictory data were put into a separate list for the client. Unknown characteristics were not filled with guesses.
Result
40,000 cards were processed and delivered within four weeks as CSV for import into the client's catalog management system.
On an agreed review sample of 2,000 cards, 98.1% were accepted by the client's QA team on the first pass without rework. A card counted as accepted when its category and all mandatory attributes matched the guideline.
The remaining 38 cards were corrected and sent for re-review. The team also checked the main set for the error types that were found.
Basis of results
Sample review protocol and correction log. The 98.1% figure refers to the reviewed cards, not to an independent review of the entire catalog.
