What type of requirements identify broad characteristics of a system, often deemed nonfunctional by analysts?

Nonfunctional requirements are essential in the context of software development as they specify the criteria that can be used to judge the operation of a system, rather than specific behaviors. These requirements often encompass a variety of attributes such as performance, scalability, security, usability, and reliability. They define "how" a system performs its functions rather than "what" functions it performs.

These characteristics are crucial for ensuring that the system meets the needs of its users and remains effective under different conditions. For instance, a nonfunctional requirement might specify that the system must handle a certain number of transactions per second, or that it must be accessible to users with disabilities. By focusing on these broader characteristics, developers can ensure that the system not only meets its primary functional goals but also delivers a satisfying user experience and meets regulatory or organizational standards.
