Lists Wave · Supply assessment
Numbers you can plan around.
Who to leave out is settled at the same moment as who to include. Rows that cannot be verified are separated from rows that failed verification. What arrives is a file whose every column has a written definition.
Re-check scheduling
Deciding how often each part of a file needs looking at again, by how fast it goes out of date.
Decay review
Identifying the records that have stopped being current, and how many of them there are.
Recency statement
Saying how old each part of a file is, so decisions about what to use are made with that in view.
If you need this verified independently, say so at the start.
