The Goal Diagram

Goal diagrams show relationships, dependencies and conflicts between the goals of a system, as well as the intention and the weight which stakeholders have in regard to the goals. In doing so, they can increase the overall acceptance of a system by giving those involved a better understanding of the scope and goals that the system will have. They make it easier to assess the relevance of prospective goals and can be used as a possible starting point for the definition of requirements. The relationship between a goal, its stakeholders and their respective weights make it possible to prioritize goals more easily.
