The Cyber-planner gathers data from a number of sources to work out strategies and calculate decisions based on the probability of success.
A Cyber-planner first appeared in The Wheel in Space. The Cybermen looked to the Cyber-planner for orders when they were planning their invasion of the space station.
A modified Cyber-planner appeared in The Invasion. It was installed on Earth and acted as a communications platform between Vaughn and the Cybermen.
