Non-Functional Requirements: Examples and a Complete Guide

In software development, non-functional requirements are an essential aspect that often gets overshadowed by functional requirements. However, they are just as crucial for ensuring the overall success of a system. Non-functional requirements (NFRs) focus on the "how" rather than the "what" of a system, addressing aspects such as performance, scalability, security, usability, and maintainability. Understanding these requirements is key to developing systems that not only meet user needs but also perform optimally under various conditions. This article explores examples of non-functional requirements and their significance in the development process, along with a guide to managing and testing these requirements.
