What a Customer Data Platform Does—and What to Check
A customer data platform, or CDP, brings customer information from multiple sources into profiles that other workflows can use. Microsoft describes its Customer Insights product as a CDP that unifies customer data. The practical question is which records are combined and whether the resulting profile is accurate enough for the intended task.
Identify the data problem first
List the systems and the information each one controls. Define the decision that is difficult today: recognising a returning customer, reconciling preferences or preparing a consistent audience. A platform purchase should follow that use case rather than begin with a promise to collect every available field.
Review identity matching
Ask which identifiers are used to link records and how conflicts are handled. A shared address or similar name can belong to different people. Keep uncertain matches distinguishable and require a way to inspect or reverse an incorrect merge. Do not let one confident-looking profile hide disagreement between its source records.
Define source and update rules
Choose which system is authoritative for each field, how changes arrive and what happens when a value is removed. Retain the source and review date needed to explain a result. Combining records does not automatically establish permission to use every field for every marketing purpose.
Test the downstream effect
Follow a correction, withdrawal and duplicate-resolution event through to the audience or workflow using the profile. Check access, exports and retention. Judge the CDP by whether it improves the specified task with understandable controls, not by the volume of data it can accumulate or a claim that unified data guarantees more sales.
