Incremental delivery less realistic evaluation about practical use of software (True/False);

False More Realistic

functional requirements may be more critical than non-functional requirements. If these are not met, the system may be useless.

T

The software requirements document is the official statement of what is required of the system developers.(T/F)

Requirements engineering

The process of establishing the services that the customer requires from a system and the constraints under which it operates and is developed.
