Study Notes
Functional Requirements (FRs)
- FRs define what the software does.
- They describe the specific functions and behaviors the system needs.
- They detail features and how the system should operate.
- Typically framed using phrases like "The system shall..." or "The system will...".
- Examples include user authentication, data storage, and search functionality.
Non-Functional Requirements (NFRs)
- NFRs describe how the software should behave.
- They define qualities, performance, and usability constraints.
- They specify how the system performs or is used.
- Typically framed using phrases like "The system should..." or "The system must...".
