During the administration of Salvador Allende in Chile, in the early 1970s, Beer was closely involved with a visionary project, Cybersyn, to apply his cybernetic theories in government. The project's ultimate goal was to create a network of computers and communications equipment that would support the management of the state-run sector of Chile's economy; at its core would be an operations room where government managers could view important information about economic processes in real time, formulate plans of action, and transmit advice and directives to managers at plants and enterprises in the field. However, consistent with cybernetic principles and the ideals of the Allende government, its designers aimed to preserve worker and lower-management autonomy instead of implementing a top-down system of centralised control. The system used a network of about 500 telex machines located at enterprises throughout the country and in government offices in Santiago, some of which were connected to a government-operated mainframe computer that would receive information on production operations, feed that information into economic modelling software, and report on variables (such as raw material supplies) that were outside normal parameters and might require attention. The project, implemented by a multidisciplinary group of both Chileans and foreigners, reached an advanced prototype stage, but was interrupted by the 1973 coup d'état.
