摘要：Role-based goal modeling demonstrates an improvement on stakeholders� role representation and its data element in modeling a system to-be. Since the requirements might be contributed from multi stakeholders, several goals are possible to rely on similar sources of requirements. In another scenario, other stakeholders may interact with the outcome from other sub goals, where this demonstrates the occurrence of dependency. Dependency implies different feasibility and adequacy of each goal and sub goal. Data dependency happens when the data can either be an input or output from one goal to another goal. Consequently, the data has been changed or intervened from one goal to another. This paper discusses the integration of data element into role-based goal modeling from the aspect of: (i) how to form the data dependency in role-based goal realization graph and (ii) how to assess the new formation in terms of feasibility and adequacy. The conflict and priority of the data dependency will be determined in order to estimate the complexity and risk along the process. This new improvement of goal modeling will be validated using a real case study taken from Plant Integrated System.
