Functional Requirements

Functional requirements specify what a system or a component must do to fulfill its intended purpose. These requirements outline the essential functions that the system or component must perform, detailing inputs, outputs, behavior, and interactions. Functional requirements are critical in software development as they guide the design, development, and testing processes, ensuring that the system meets user needs and expectations. They include features such as data processing, calculations, and business rules. These requirements are often documented in a requirements specification document, serving as a reference for developers and stakeholders throughout the project lifecycle. Properly defined functional requirements help avoid ambiguity, reduce development risks, and ensure that the final product is functional, efficient, and user-friendly.
