Definition
The critical aspects of a system that are not directly visible to users but significantly impact the overall user experience, including performance, latency, scalability, high availability, security, compliance, recoverability, maintainability, and reliability, which must be carefully considered and addressed in solution design
Summary
Non-functional requirements play a critical role in software development by defining how a system should perform rather than what it should do. They encompass various attributes such as performance, security, usability, and reliability, which are essential for user satisfaction and system effectiveness. Understanding and implementing these requirements can significantly impact the success of a software project. Incorporating non-functional requirements requires careful planning, measurement, and management. Teams must navigate challenges such as ambiguity and trade-offs while ensuring that these requirements are met throughout the development lifecycle. By following best practices and continuously evaluating these criteria, developers can create robust systems that meet user needs and expectations.
