Information on Non-Functional Requirement
While a functional requirement defines the services and functions that
the system should provide, a non-functional requirement describes
the qualities or attributes that it must posses. A non-functional
requirement may also describe the constraints under which
the system should operate, and on the way in which
the system is to be developed. A non-functional requirement could also provide definitions of system interfaces and information
about the application domain of the system (for example, how
to carry out particular types of computation).
