SOFTWARE ENGINEERING

Detailed explanation-1: -What are the key types of non-functional requirements? The most common ones are performance, scalability, portability, compatibility, reliability, availability, maintainability, security, localization, and usability.

Detailed explanation-2: -Nonfunctional Requirements (NFRs) define system attributes such as security, reliability, performance, maintainability, scalability, and usability. They serve as constraints or restrictions on the design of the system across the different backlogs.

Detailed explanation-3: -Non-Functional Testing is a type of testing used to evaluate a software application’s performance, usability, dependability, and other non-functional characteristics. It is intended to test a system’s readiness according to non-functional criteria that functional testing never considers.

Detailed explanation-4: -Non-Functional Requirements (NFRs) define the qualities, or overall characteristics, of a system and may impose constraints on the design or implementation. These qualities, many of which are documented in ISO/IEC Standard 25010, may include functionality, performance, security, and maintainability to name a few.
