Production Excess is a term used to describe the amount of goods produced beyond what is needed or expected. OVERRUN is a related term which refers to the amount of goods produced in excess of the planned or expected quantity. This can be due to a variety of factors, such as an increase in demand, a change in production methods, or a misjudgment of the market. In either case, it can lead to a surplus of goods that must be sold at a discounted rate or disposed of.
