In
engineering, a requirement is a singular documented physical and functional need that a particular product or service must be or perform. It is most commonly used in a formal sense in
systems engineering,
software engineering, or
enterprise engineering. It is a statement that identifies a necessary attribute, capability, characteristic, or quality of a system for it to have value and utility to a user.
In the classical engineering approach, sets of requirements are used as inputs into the design stages of
product development. Requirements are also an important input into the verification process, since tests should trace back to specific requirements. Requirements show what elements and functions are necessary for the particular project. This is reflected in the
waterfall model of the software life-cycle. However, when
iterative methods of software development or
agile methods are used, the system requirements are incrementally developed in parallel with design and implementation.
Requirements engineering is the set of activities that lead to the derivation of the system or software requirements. Requirements engineer...
