Study Notes
Functional Requirements
- Define specific behaviors or functions that a system must perform.
- Serve as a guide to what the system should do, typically including inputs, outputs, and user interactions.
- Can be directly tested using test cases to ensure the system meets specified functions.
Purpose of Functional Requirements
- Establish clear criteria for system functionalities, aiding in design and development.
- Ensure all stakeholders have a shared understanding of expected software capabilities.
Nonfunctional Requirements
- Specify criteria that judge the operation of a system, including quality aspects.
- Focus on performance, usability, security, reliability, and scalability rather than specific functionalities.
Aspects of Nonfunctional Requirements
- Performance: Response times, throughput, and resource consumption under load.
- Usability: User experience, accessibility, and interaction design.
- Security: Protection measures against unauthorized access and data breaches.
- Reliability: Consistency of performance and error handling.
Differences Between Functional and Nonfunctional Requirements
- Functional requirements are concerned with "what" the system does; nonfunctional requirements are about "how" the system performs its functions.
- Functional requirements can be directly validated through test cases; nonfunctional requirements often require indirect evaluation through metrics and usability testing.
