What is Requirement

1.

Represents a need that an Information System should fulfill. Requirements can be functional (what the software or component should do, a functionality), non-functional (how the system will do, that is, constraints or qualities) and environmental (imposed constraints such as legal restrictions or standards). This classification can be seen from the user point of view (understandable for stakeholders) or from the system point of view (on a technical and more detailed level).
