A useful result of a process.
This result can include files, documents, products, parts of a product, services, process descriptions, specifications, and invoices. A key distinction between a work product and a product component is that a work product is not necessarily part of the end product. (See also “product” and “product component.”)
In CMMI models, the definition of “work product” includes services, however, the phrase “work products and services” is sometimes used to emphasize the inclusion of services in the discussion.
