The decision in the W&W Group to introduce data quality measures had an impact on a wide variety of positions. The issue of the quality of personal master data should be pursued as part of a holistic approach. The processes for the matching should be automated, versioning of the processes for traceability and simple usability for the data stewards to review possible matches should be created.
In addition, software for data quality and a clearing house for data should be established as part of the master data management approach. In the master data project, a central instance for consolidated personal data was created with the Uniserv Customer Data Hub. In doing so, W&W essentially pursued three goals:
- Group-wide data governance: establishing a group-wide standard for maintaining personal master data
- Central partner system: Introduction of a central group partner system based on a master data management platform
- Clearing house: Setting up a clearing house for personal master data
One of the priorities was the creation of a central office for data quality. The data quality, in turn, forms the basis for the 360-degree view of the customer.
When setting up data governance for personal master data, the focus was on the creation of a central, group-wide set of rules for maintaining personal master data. On the other hand, the establishment of the set of rules in the line organization, in sales and in projects, compliance with the set of rules during operation through quality measurements and the ongoing assurance of the quality of personal master data were elementary. The basic goal was to create a uniform procedure in the group with regard to the quality, input and maintenance of personal master data.
