What is recoverability in non functional requirements?

Recoverability – Logical Requirement: The ability of the system to resume business functionality upon logical failure of application managed business data. A systems RPO is derived from this and other requirements.

Which is a non-functional requirement?

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. They ensure the usability and effectiveness of the entire system.

What is scalability in non functional requirements?

Scalability is a non-functional property of a system that describes the ability to appropriately handle increasing (and decreasing) workloads. Scalability competes with and complements other non-functional requirements such as availability, reliability and performance.

Is usability a functional or non-functional requirement?

Usability is a non-functional requirement. As with other non-functional requirements, usability cannot be directly measured but must be quantified by means of indirect measures or attributes such as, for example, the number of reported problems with ease-of-use of a system.

What is an example of a functional requirement?

In other words, a functional requirement will describe a particular behaviour of function of the system when certain conditions are met, for example: “Send email when a new customer signs up” or “Open a new account”. A functional requirement for an everyday object like a cup would be: “ability to contain tea or coffee without leaking”.

What is the abbreviation for 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 behaviors. They are contrasted with functional requirements that define specific behavior or functions.
