In a newly developed production control system, a safety control ought to be included as a means of ensuring a more rational control system for achieving efficiency. Such a system does not hold any meaning in itself unless accompanied with appropriate ways to make it practicable. A firm would have a number of function groups. Each of these groups would have specific functions or duties to perform. Their production activities would be planned at the level of departmental management. The planning will take such forms as production, quality and safety planning, and so far as each department would order the line from its own standpoint, scientific production activities could not be expected. All the programmes must, therefore, be integrated and coordinated by a supervisor.
