01
The situation
Before
Each ERP had its own vendor master; category managers compared spend by hand; the same supplier group appeared as eleven vendors, and the agreements were negotiated eleven times.
02
What was built
The domains
Golden suppliers from three ERPs matched on VAT IDs, DUNS and verified bank accounts, placed in a legal hierarchy from registry data and a purchasing hierarchy by category; the credit-cap business rule over open purchase orders; the on-time-receipt measure on the golden supplier by month.
03
How it runs
Day to day
Category managers pivot spend and on-time performance by supplier group and category; the steward queue handles new vendors from any ERP; the agreements are on the group.
