Chapter 2 Requirements model basics
A requirements model is a documentary model that helps you list and define precisely what actions must be implemented during a development process.
Requirements are listed in document views; their links with design objects (objects from other types of models), external files or other requirements are managed in traceability matrix views; and they can be globally assigned to users and groups in user allocation matrix views.
A requirements model sets and reminds what is at stake and what must be done during a development process.
A requirements model is the reference model which defines the tasks and orientates the work of all users and groups involved in a development process.
