Data

Collection, quality, joins and the gaps nobody mentions until the numbers disagree.

Marketing numbers come from many systems, and each one collects, cleans and joins data in its own way. This topic covers the work under a dashboard: how data is collected, where it loses quality, how records are joined across tools, and the gaps that stay hidden until two reports disagree. The pieces explain the mechanics first, so you can judge the numbers you already have.
