Same Same But Different
The difference between solving data quality issues for party (customer, supplier and other business partner) master data and product master data was discussed 7 years ago on this blog in the post Same Same But Different.

Since then I have worked intensively with both party master data and product master data and the data quality challenges organizations have within these domains.
Building on the findings from 7 years ago and recent experiences, I think there are two areas it is worth emphasizing on:
- Data Quality Dimensions: All dimensions are important and they support each other in solving the issues. But there are some differences as explained in the post Multi-Domain MDM and Data Quality Dimensions. In my mind, uniqueness is the worst pain for party master data and completeness is the worst pain for product master data.
- External Data Sources: The use of data sources was examined in the post 1st Party, 2nd Party and 3rd Party Master Data. In my mind, extensive utilization of third party data is paramount for party master data quality and effective exchange of second party data is paramount for product master data quality.
A Sharing Concept
For solving both party master data and product master data quality issues you need Multi-Domain MDM for business ecosystems as proposed in the Master Data Share concept.
