User requirements can generally be divided into two sets of requirements:
-
Functional Requirements: These describe what the system should do. They outline specific behaviors, functions, and capabilities that the system must provide to meet the needs of the users. Examples include user authentication, data processing, and reporting features.
-
Non-Functional Requirements: These define how the system performs its functions rather than what functions it performs. They include attributes such as performance, usability, reliability, security, and maintainability. Non-functional requirements ensure that the system is effective and efficient in meeting the functional requirements.
Both sets of requirements are essential for successful system design and development, as they collectively ensure that the end product satisfies user needs and expectations.
