A general introduction to PERT COST, an innovation in the field of management. This technique employs a networking, statistical and scheduling methodology using advanced data processing procedures. The PERT COST technique is based on the principle that planning must be developed in a manner that facilitates its use as a management control tool and a management control system must use as its base the planning that governs the program. Accordingly, PERT COST can be used in both the planning and control functions of management. (Author).
