These attributes do not tell what the system does but how well it does it. Nonfunctional Requirements (NFRs) are intended to specify ‘system qualities,’ various systems attributes that are not directly related to their functionality.
NFRs influence Teams, ART, Solution Train, and Portfolio backlogs. NFRs are persistent qualities and constraints typically revisited as part of the definition of done (DoD) for each Iteration, PI, or release.
Performance: How fast a system should respond to requests.Nonfunctional Requirements (NFRs) are system qualities that guide the design of the solution and often serve as constraints across the relevant backlogs.Īs opposed to functional requirements, which specify how a system responds to specific inputs, nonfunctional requirements are used to specify various system qualities and attributes, such as: Common proverb Nonfunctional Requirements
