Back in June, while writing about composable CDPs, I asked a question and then, like a distracted person, walked straight past it.
When two systems disagree about something like a customer's email opt-in status, which value wins, and is that rule written down anywhere?
I gave it one line of answer. In packaged systems the vendor sorts it out for you, in composable systems the work goes to your data team. Both true, but neither one tells you which number is right. That has bothered me on and off ever since.
