GDP measures the monetary value of final goods and servicesâthat is, those that are bought by the final userâproduced in a country in a given period of time (say a quarter or a year). It counts all of the output generated within the borders of a country.
Product audit â An examination of a particular product or service (hardware, processed material, software) to evaluate whether it conforms to requirements (that is, specifications, performance standards, and customer requirements). Process audit â A verification that processes are working within established limits.
There are three discrete types of audits: product (which includes services), process, and system. However, other methods, such as a desk or document review audit, may be employed independently or in support of the three general types of audits. Some audits are named according to their purpose or scope.
