NFD is an acronym that stands for Non-Functional Requirement(s). It is a term commonly used in the field of software engineering and systems development to refer to the specific qualities or attributes that a system or software application must possess, beyond the basic functionalities or features it provides. NFDs are essentially the criteria or constraints that define how a system should perform in terms of reliability, security, usability, scalability, performance, maintainability, and other non-functional aspects.
Unlike functional requirements, which describe what the system should do, NFDs focus on how the system should behave or operate. They are set to ensure that the system meets the expectations and demands of its users and stakeholders, taking into account factors such as efficiency, responsiveness, accessibility, compatibility, and user experience.
NFDs are typically defined during the early stages of system design and development, often through collaboration with stakeholders and domain experts. They help to establish a clear understanding of the overall system requirements and guide the design decisions and implementation strategies. NFDs are often documented in requirements specifications and used as a reference to evaluate and verify the system's performance and capabilities throughout the development lifecycle.
