Which is not non functional requirements?

Non-Functional Requirements are the constraints or the requirements imposed on the system. They specify the quality attribute of the software. Non-Functional Requirements deal with issues like scalability, maintainability, performance, portability, security, reliability, and many more.

What is reliability in non-functional requirements?

DEFINITION: Reliability is the extent to which the software system consistently performs the specified functions without failure. ELICITATION: Reliability requirements address the user concern for the system’s immunity to failure.

What is a valid non-functional requirement?

Functional requirements apply to the specific behaviors of a system, whereas non-functional requirements form measurable criteria that can be used to gauge the success of an overall system, solution, or product.
