In a nutshell, a computerized system will be replacing the old system of simply rotating between positions, where generous breaks were thrown into the mix. At Disney World, cast members go to their attraction and scan their ID through a computer. Cast members go to their computer- assigned position and stay there until they are bumped by another cast member. Next, instead of bumping the next cast member in the old rotation, just- bumped cast members walk back to the computer and scan their ID again.
Cast members continue the process throughout their assigned shift.
With rotations, Disneyland cast members now average about three breaks and a lunch per eight-hour shift. Cast Deployment is designed to wring out the excess breaks that evolved under the rotational system. WDW has it, it stinks. It gets rid of the old rotation system. And in deployment, you do not know when you will be released from a position.
