-Storage:
It involves holding of goods in proper (i.e., usable or saleable) condition from the time they are produced until they are needed by customers (in case of finished products) or by the production department (in case of raw materials and stores); storing protects the goods from deterioration and helps in carrying over surplus for future consumption or use in production.
