Non-functional requirements (NFRs) are crucial aspects of a system that define its operation rather than its specific behaviors. They describe how a system performs certain functions and are essential for ensuring the system's overall quality, usability, and performance. In the context of a Prescriptive Design Requirement (PDR) for prescriptive delivery, non-functional requirements address various system attributes such as performance, security, scalability, and maintainability.

KEY VALUE: Automating the recalculation and updating of non-functional requirements allows the system to continuously adapt to changing conditions, optimizing performance without manual intervention and ensuring the solution meets all prescribed design standards. |
Purpose of Non-functional Requirements
Define system attributes and capabilities by describing how the system should perform and operate, rather than focusing on specific functional behaviors.
Ensure Overall System Quality through use of NFRs as a critical component for defining the system's overall quality, usability, and performance.
Enable continuous adaptation and optimization by automating the recalculation and updating of NFRs to allow the system to continuously adapt to changing conditions.
Promote horizontal and vertical scalability requirements that enable the system to scale effectively to handle increased workloads or resource needs.
Strengthen security and compliance using NFRs related to data protection, authentication, authorization, and regulatory compliance to safeguard the system.
Enhance user experience and satisfaction with NFRs focused on usability, accessibility, and reliability contribute to a positive user experience.
