Avoiding Bias in Centralized Marketing Data: The Path to True Measurement Ownership

A "single source of truth" sounds like the end of measurement chaos, but there is an uncomfortable reality most teams discover too late: a single source of truth can still be a single source of bias, because centralizing marketing data is not the same as owning measurement.

What you end up with isn't a neutral performance foundation. It's a well-organized version of the same distortion.

Organizing data creates order.
