McKinsey was doing some work for their dept. I asked him what they did. He said, "McKinsey asked us for lots of information. Then they put it into a dossier and gave it back to us."
Shifting context a bit, I used to experience school classmates complaining to me about some problem they had, and, when I repeated their information back to them, thanking me for being helpful.
That didn't feel like it was helpful to me, but other people seem to disagree. This can't even be explained by the internal communication barriers that exist within large organizations - an organization of one person has no such barriers.
