The role-based goal model in this paper is being discussed in two aspects which are (i) on how to develop the role-based goal realization and (ii) on how to assess role-based goal realization graph. The reason for taken these two aspects into consideration is to demonstrate the differences in level of risk which later contribute to the selection of high feasibility and adequacy of requirements. There are four stages for developing the model are explained detail and include: (i) identifying of role and goal, (ii) formation of goal realization graph, (iii) assessment of confidence factor for each goal and (iv) determination of feasibility and adequacy of requirement.
