The Top Management Decision Simulation is an early serious game. It's a computer assisted game that's used to train managers for decision making. The game models idealized business transactions.
Development began in 1955 and somewhere in 1956 a playable version was avalaible. In May 1957 it was published.
It was featured in the AMA Management Development Seminar and the Executive Decision Making Program.
The game led to all kind of management games such as:
UCLA Executive Game n°2
IBM Management Decision-Making Laboratory
The Carnegie Tech Management Game
