Supply: The main element of operations management is supply. Continuous supply of inputs is required to transform them into output.
Efficiency: You have learned that a continuous supply of inputs is an important element of operations management. We can further divide this to include another parameter, that is, efficiency.
Quality control: A system that maintains a desired level of quality in a product or service is quality control. It deals with detecting defects in the operations that are involved in the production process. It also decreases the operational cost by reducing the losses due to defects.
