Stakeholder dialog is central to these needs. Additionally, analysts must be able to analyze the developing requirements. The needs can be supported through a dialog support system and its meta-model. We have defined a dialog support system and its dialog meta-model. Each statement is either passive information or an active operation.
Statements are instances of the dialog statement model.
As the dialog expands, dialog goals can be compared against the dialog to determine their status. The meta-model can be instantiated to define a typical process model, with a distinction of process and product. Consider information statements as products, operation statements as actions, and dialog goals as defining a process model. As such, the dialog meta-model is a process model with an explicit representation of the process goals and enactment history. Such a meta-model is suitable for modeling the process of requirements development.
