What are the non-functional requirements of software?

Non-functional requirements are global constraints on a software system e.g., development costs, operational costs, performance, reliability, maintainability, portability, robustness etc.

What is the meaning of non-functional requirements?

In systems engineering and requirements engineering, a non-functional requirement (NFR) is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviours. They are contrasted with functional requirements that define specific behavior or functions.

What does NFR describe?

If you think of functional requirements as those that define what a system is supposed to do, non functional requirements (NFRs) define constraints which affect how the system should do it. While a system can still work if NFRs are not met, it may not meet user or stakeholder expectations, or the needs of the business.
