Functional Vs Non Functional Requirements (NFRs) While building any application, the focus is often on the Functional requirements. These are capabilities and features that the users expect from the application. The functional requirements could vary from one group of users to the other and from one domain to the other.
Non Functional Requirement (NFR)
A non-functional requirement is a requirement that specifies criteria that can be used to judge the operation of a system, rather than specific behaviors. They are contrasted with functional requirements that define specific behavior or functions. The plan for implementing functional requirements are detailed in the system design.

A single non-functional requirement, such as a security requirement, may generate a number of related functional requirements that define system services that are required. In addition, it may also generate requirements that restrict existing requirements. Non-functional requirements arise through user needs, because of budget constraints,

The definition for a non- functional requirement is that i t essentially specifies . how the system should behave. and that it is a constraint upon the system's behaviour. One could also think of non- functional requirements as to . quality attributes. for a system.
