    Question

    In requirement analysis, which of the following best

    defines functional requirements?
    A The constraints on the system design or implementation. Correct Answer Incorrect Answer
    B The specific behaviors or functions a system should exhibit. Correct Answer Incorrect Answer
    C The performance metrics like speed and reliability. Correct Answer Incorrect Answer
    D The rules governing system operation. Correct Answer Incorrect Answer
    E The documentation standards for system development. Correct Answer Incorrect Answer

    Solution

    Functional requirements describe the specific behaviors or functions a system must exhibit to fulfill its purpose. These requirements outline what the system should do, including inputs, outputs, processes, and interactions. Examples include login authentication, data processing, and user interface features. Functional requirements are derived from user needs and form the foundation for design and testing. They ensure the system delivers the intended functionality to meet business objectives. Why Other Options Are Incorrect: 1. Constraints on the system design or implementation: Refer to non-functional requirements, such as limitations on technology. 2. Performance metrics: Focus on non-functional aspects like speed and reliability. 3. Rules governing system operation: These may include business rules but are not functional requirements. 4. Documentation standards: Not related to system functionality. Functional requirements are essential for defining what a system should do, guiding development and testing efforts.
