Control Function in Production Management:

Controlling is a sub system of the production system where a part of the output is monitored for feedback signals to give corrective action, if required. The management and control of inventory is a general problem to all kinds of organisations. Inventory control refers to the planning for optimum quantities of materials at all of the stages in the production cycle and evolving techniques which would make sure the availability of planned inventories.

Quality control assures that resulting product shall perform its intended function. Thus, this is concerned with the prevention of defects so that items can be made right at the first time. To attain this several activities are needed to perform. Inspection and control of raw materials ensure that they meet specification. Statistical quality control (SQC) attempts to evaluate machines, materials by observing capabilities and trends in variation so that continual analysis and production can be made to the wanted quality level.
