Requirement

A requirement in software development refers to a specification that outlines the features, functions, and constraints the software must meet to fulfill user and business needs. Requirements guide the design, development, and testing of the software, ensuring it meets expectations.

Key components include:

• Functional Requirements: Define what the software should do, such as user actions and system behavior.
• Non-Functional Requirements: Specify qualities like performance, security, and scalability.
• User Requirements: Focus on the needs and expectations of end users.
• System Requirements: Describe technical aspects, such as architecture and integration.
• Business Requirements: Outline organizational goals the software must achieve.
• Regulatory Requirements: Ensure compliance with legal standards like GDPR or HIPAA.
• Traceability: Ensures each requirement is tested and verified throughout development.
• Change Management: Tracks and manages any updates or changes to requirements.

Well-defined requirements ensure the software meets intended goals, avoids scope creep, and delivers quality.
