The highest managerial authority under the Taean system is the party committee. Each committee has approximately 25 to 35 members elected from the ranks of managers, workers, engineers, and the leadership of "working people's organizations" at the factory. A smaller "executive committee", about one-quarter the size of the regular committee, has practical responsibility for day-to-day plant operations and major factory decisions. The most important staff members, including the party committee secretary, factory manager, and chief engineer, make up its membership. The system focuses on co-operation among workers, technicians, and party functionaries at the factory level.
