Even if it is verifiable and attainable, and eloquently written, if it is not necessary, it is not a good requirement.

If a requirement is not attainable, there is little point in writing it.

A good requirement should be clearly stated..

What are the functional requirements of a project?

Functional requirements define the basic system behaviour. Essentially, they are what the system does or must not do, and can be thought of in terms of how the system responds to inputs. Functional requirements usually define if/then behaviours and include calculations, data input, and business processes.
