The official definition for a nonfunctional requirement identifies how the system should respond: " A nonfunctional requirement is a assertion of how a system must respond, it is a limitation upon the systems tendencies. " nonfunctional requirements specify all the staying requirements not covered by the functional requirements. They designate criteria that judge the operation of a system, rather than specific manners, for example: " Display in the patient's essential signs need to respond to a change in the patient's status inside 2 mere seconds.
