D. Volere Requirements Knowledge Model
The Volere Requirements Knowledge Model (Figure D.1) provides a language for the knowledge that you discover and accumulate during your requirements activities. We present it as a guide to the information you need to discover, and as a tool for communication between the various stakeholders on your project. The model can also serve as your specification for which requirements knowledge you plan to discover and trace. Your own process must define who gathers which information, to what degree of detail, and how it will be packaged and reviewed.
