What are non-functional requirements?
Answer Posted / rahul
In general, functional requirements define what a system is supposed to do whereas non-functional requirements define how a system is supposed to be. Non-functional requirements are often called qualities of a system. Other terms for non-functional requirements are "constraints", "quality attributes", "quality goals" and "quality of service requirements". Qualities, that is, non-functional requirements, can be divided into two main categories:
Execution qualities, such as security and usability, which are observable at run time.
Evolution qualities, such as testability, maintainability, extensibility and scalability, which are embodied in the static structure of the software system.
