The document discusses master data synchronization between retailers and suppliers. It proposes that EDI (electronic data interchange) combined with GDS (global data synchronization) can provide a successful solution. GDS allows automatic interchange of product information between partners using a central data pool to store standardized attributes. Implementing GDS reduces errors from inaccurate master data and makes the new item listing process more efficient. The presentation promotes a GDS working group between Baltic retailers and vendors to develop industry standards and a collaboration model.
