specification
A standard template should be developed and used for a specification, arguing that this leads to requirements that are presented in a consistent and therefore more understandable manner.
Validation
Examines the specification to ensure that all requirements have been stated unambiguously; that inconsistencies, omissions, and errors have been detected and corrected
negotiation
It isn’t unusual for customers and users to ask for more than can be achieved, given limited business resources. It’s also relatively common for different customers or users to propose conflicting requirements, arguing that their version is “essential for our special needs.”
Elaboration
This task focuses on developing a refined requirements model that identifies various aspects of function, behavior, and information.
