Although manufacturing output is projected to rise, increases in productivity among industrial production managers and the workers they supervise will limit growth in employment of these managers. Productivity gains among managers will stem from the increasing use of computers for scheduling, planning, and coordination. Productivity gains among workers will limit both the number of employees in factories and the need for supervision. In addition, more emphasis on quality in the production process has redistributed some of the production manager's oversight responsibilities to supervisors and workers on the production line. Because production managers are so essential to the efficient operation of a plant, they have not been greatly affected by recent efforts to flatten management structures. Nevertheless, this trend has led production managers to assume more responsibilities and has limited the creation of more employment opportunities.
