For example, consider a car manufacturer that offers an incentive program to employees to buy cars. To construct BVT customer records, the data steward identifies the contributing source systems as the customer relationship management (CRM) system and the human resources (HR) system. The data steward trusts the employee address and telephone number from the HR system more than the same information in the CRM system, because employees are required to notify the human resources department of any changes to their contact information.

Data Director

is a special type of contributing source system. Usually, data stewards set

Data Director

to the highest trust level of all contributing systems, which means that when a user edits data in

Data Director

, the edit is preferred over other source systems. You can also choose to override the automated BVT process and select a cell value you know is accurate.

For example, the following table shows data coming from two source systems and from

Data Director

:

Because

Data Director

has the highest trust score for telephone numbers, the updated telephone number is used. The data steward can add rules that cause the trust value to increase or decrease for a system. For example, if the telephone number is subsequently updated in the HR system, the system might prefer that telephone number because it was updated most recently.
