Final answer:
Non-functional system requirements are important qualities of a system. Five examples include performance, reliability, security, scalability, and usability. These requirements are usually more important to the end-user or the developer, depending on the specific requirement.
Step-by-step explanation:
Non-functional system requirements pertain to the qualities and characteristics of a system, rather than its specific functionality. Here are five different non-functional system requirements:
- Performance: This requirement refers to how well a system performs its tasks. It can include factors such as response time, throughput, and scalability. Performance is usually more important to the end-user, as they want a system that is fast and efficient.
- Reliability: Reliability refers to the system's ability to consistently perform its intended functions without failure. It includes factors like uptime, failure rates, and fault tolerance. Reliability is important to both the end-user and the developer, as a reliable system ensures user satisfaction and reduces maintenance efforts.
- Security: Security requirements aim to protect the system and its data from unauthorized access, manipulation, and destruction. It includes aspects like access control, encryption, and authentication. Security is crucial for both end-users and developers, as it safeguards sensitive information and prevents breaches.
- Scalability: Scalability is the system's ability to handle increasing workloads and adapt to changes in demand. It includes factors like resource utilization, load balancing, and elasticity. Scalability is usually more critical to developers, as they need to ensure the system can handle future growth and accommodate increasing user requirements.
- Usability: Usability refers to how easily and efficiently users can interact with the system. It includes factors like user interface design, navigation, and user assistance. Usability is typically more important to the end-user, as they want a system that is intuitive, user-friendly, and meets their specific needs.
