Objectiver is a requirements engineering tool that uses structured modeling to identify project requirements and generate documentation. It includes goal, responsibility, object, and operation models to define goals, assign responsibilities, identify domain objects, and describe required behaviors. A demonstration of the tool modeling a user login process showed defining high-level security goals, assigning the user and system as responsible agents, and specifying operations like requesting and verifying login details.
