Operations are the tasks used to create and deliver products and services for customers. The concept includes all support functions required to ensure that the products and services are provided in a timely manner. Thus, the materials management, production, warehousing, and delivery functions may be considered the "core" operations functions, while accounting, engineering, sales, and marketing may be considered "support" operations.

The operational results of a business are closely watched, since they are the best indicator of how well an entity's strategy is succeeding in the marketplace.
