One of the things I have learned is that a lot of middle management don't have tangible roles, so they make up for this by recognition, which is usually "presence." So they have meetings to be seen, stay relevant, and look important. Like, how do you measure management as a product? It's a social game, primarily. I'm not saying all or any large percentage of management is like this, but there are a LOT.
"What do you say you DO here, exactly...?" And they start to sweat.
Edit: Clarifying I know there ARE effective ways for an organization to do this, but that doesn't mean they do or even know how :/
