Lets consider a chain of supermarkets in the United States for our example. If you know that the standard output for a tire manufacturer in terms of rubber is $2.25 per unit, then you spend more than the industry average to produce a tire. Calculating and tracking your manufacturing efficiency rate helps you identify opportunities to improve your people, processes or products by measuring how well you manufacture now versus how efficient you could be based on established standards. It is common sense that when input increases, the output will also increase. Operational efficiency is a metric that measures the efficiency of profit earned as a function of operational costs.
