I agree, the DMM's days are numbered. Except maybe in SAM, where the Foreman could be the layer they will eliminate, leaving the DMM to technical management of the checks.
To an extent, I can understand why they don't want to pay a DMM 200+ to people manage. They can pay an Ops Manager considerably less than that to sign the leave forms and fwd the odd email and he can also be "accountable" (sackable) if he doesn't tow the line for the CAMO.
