A person that mistakenly believes they are adding value is a member of the Value Add Group.
Typically, VAG's are bossy and like to delegate work to others, thinking that their direction is of enormous value.
Conversely, if a lazy person is aware of their lack of work ethic and still allows others to do their job, they are not a VAG, but a dick.
"He forwards every email to someone else so they can do the work, but then provides status updates to his manager to make it look like he's getting the job done. Such a VAG..."
From the mind of a VAG: "I am the overseer of this operation, so it is critical that I don't get bogged down in the minutia. I'll leave those activities for the lesser humans that don't have MBAs."
