Tangentially related, but I've recently started distinguishing verification and validation in my data cleaning work:

verification refers to "is this dataset clean?" or the more precise "does this dataset confirm my assumptions about what a what a correct dataset should be given its focus"

validation refers to "can it answer my questions?" or the more rigorous "can I test my hypotheses against this dataset?"

So I find this interesting (but in hindsight unsurprising) that similar definitions are used in other fields. Would you have a source for your defintions?

They're fairly standard terms from "old style" project management - they show up in the usual V Model of Waterfall vein.
