Product requirements

In the quality management standard DIN EN ISO 9000:2005 requirement is defined as " a requirement or an expectation that or set the usually assumed or required ." The term usually refers to the definition that the presence of an expected feature is more the rule than the exception. Thus, for example, when buying a car a " solid rust protection" expected although this was not explicitly formulated. Furthermore, the standard foresees the use of a determiner for the term requirement. This modifier is for the purpose to limit the range described by the term requirement. For example, the term "product request" is used to describe a requirement to a product and at the same time to achieve a clear separation of the product creation process ( process requirements ).

Requirements can be formulated by various interested parties such as the clients of a product, the engineers responsible for the development, etc. The requirements are generally recorded in writing, for example, checklists, specification sheets, request lists, questionnaires, etc.

In software technology, special requirement descriptions have been established which are placed on software, see: Requirements ( computer science ).
