is the way in which companies control and optimize the money they spend. It involves cutting operating and other costs associated with doing business. These costs typically show up as "operating costs" or SG&A (Selling, General and Administrative) costs, but can also be found in other areas and in other members of the supply chain. Whether it is the money spent on goods or services for direct inputs (raw goods and materials used in the manufacture of products), indirect material (office supplies and other expenses that do not go into a finished product), or services (temporary and contract labor, print services, etc.), a company needs a mechanism by which they are not only able to save money but control costs.
