Systems Engineering has terminology for this distinction.
Verification is "does this thing do what I asked it to do".
Validation is "did I ask it to do the right thing".
- crashabr 3y agoTangentially 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?
- rkangel 3y agoThey're fairly standard terms from "old style" project management - they show up in the usual V Model of Waterfall vein. E.g. see Wikipedia: https://en.m.wikipedia.org/wiki/Verification_and_validation https://en.m.wikipedia.org/wiki/Verification_and_validation
