This chapter illustrates both the administrative and technical areas that make up a good preventive maintenance program. A procedural system of indexing scheduled work and quality control should be established by the supervisor in conjunction with the company’s standards of performance. Personnel assigned to the maintenance control system must be made familiar with all work items. The preventive maintenance program is a method of budgeting and controlling maintenance expense. The coding on the ticket will enable study of the shift for more effective coverage of the operation after evaluation of the time cards. Information on time tickets, such as the nature of breakdown and what action was taken to correct it, is only valuable to supervisory personnel for evaluation of satisfactory performance of maintenance duties. The initial organization and subsequent administration of the program is the responsibility of the supervisor of maintenance.
