non-functional requirement

The quality of the source code is a non-functional requirement.

Non-functional requirements are often called "quality attributes" of a system.

Focus on integration, also testing of functional and non-functional requirements.

It usually has no performance or non-functional requirement details.

The plan for implementing non-functional requirements is detailed in the system architecture.

Sufficient network bandwidth may be a non-functional requirement of a system.

Therefore, AS have to meet growing functional and non-functional requirements.

It also addresses the non-functional requirements that have been set for the IS.

System Testing verifies that functional and non-functional requirements have been met.

In practice, non-functional requirements are important to success.

Each functional and non-functional requirement should be traceable to one or more business drivers.

The objective is to provide confidence that the developed product meets both the functional and non-functional requirements.

The idea was that each step would be a transformation that took into account various non-functional requirements for the implemented system.

This should be contrasted with non-functional requirements which specify overall characteristics such as cost and reliability.

Other non-functional requirements will trace to other system components and be verified at that level.

Within the application boundary, non-functional requirements are associated with relevant categories and their sub-categories.

Non-functional requirements, which are unverifiable at the software level, must still be kept as a documentation of customer intent.

Adherence to the non-functional requirements is also validated post-deployment by monitoring the production systems.

Where necessary, the system will be tuned to bring nonconforming tests into conformance with the non-functional requirements.

Functional and non-functional requirements: including usability, performance, safety.

Continuous testing includes the validation of both functional requirements and non-functional requirements.

But in non-functional requirements you often need more loosely defined criteria, like satisficeable or unsatisficeable.

These help to discover non-functional requirements.

Measuring the non-functional requirements improves the work effort estimation of software development based on functional sizing alone.

Non-functional requirement are mapped to the relevant sub-categories.
