Why do I have a hunch I'm safe in assuming that one of the "Sources of the One True Data" doesn't want to have responsibility if the "One True Data" is wrong.
I've met a lot of "The Buck Stops Here with Me, but Where the Blame Stops is a Lot More Negotiable" people in my time.
I'm even more cynical than that: the project's point is to move the source of truth to my department, from the current sources. I think the current sources are engaging in some attempts at job security by trying to sabotage my efforts. This will not succeed because (unlike them) I can prove every one of my numbers by pulling the actual detail data straight from the source. Challenge one of my figures and I can provide millions of rows of detail to prove I'm right. Challenge one of their figures and they get mad and can't explain where they got it from. Which is why the powers that is want to move the data to my group in the first place.
