A single, trusted view of the customer
- Challenge
- Customer records were spread across many systems — duplicated, inconsistent and hard to trust.
- Approach
- Built the customer data and MDM capability on IBM MDM Server: standardised addresses against Royal Mail PAF; made the highest-quality source, the policy system, the trusted source for the golden record; tuned automatic-merge and review thresholds against known duplicates, with periodic sampling by data stewards who also worked the review queue; cleansed the data and managed reference data — then built a household view of each customer.
- Outcome
- Matching rates improved by 21%, and the business gained a trusted, household-level view of its customers.
