Marketing and data engineering use the same words for different things, and the cost of that shows up six weeks later as a segment refreshing daily instead of hourly.

This is a six-part field guide for closing that gap. Every part is one page you can print and take into a meeting.

The six guides

2. How to write a data request someone can act on · Published 24 September 2026<br> Six questions to read your own draft against, before you send it. Download the one-page PDF

3. What real time actually costs · Published 5 October 2026<br> Five speeds, what each one is for, and the correction window each step gives up. Download the one-page PDF

4. Same customer, different records · Week of 6 October<br> Two ways identity goes wrong, and which mistake each use can afford.
