| Summary: | Requirements analysis is the process of analyzing the requirements of various stakeholders that represent the specification of system behavior. This must be stated precisely in order to proceed to the design phase. It is noted that the current process of requirements analysis is not sufficient for identifying and representing the existence of multiple stakeholders, which could lead to various conflicts and overlapping requirements. Furthermore, the involvement of various stakeholders normally leads to inconsistencies and misinterpretation of requirements. Therefore, this study is conducted to enhance goal modeling representation, namely role-based goal modeling. Role-based goal modeling highlights each stakeholder’s role identification in discovering the intentions and requirements of various stakeholders including the integration of data elements in order to determine the dependency of data when dealing with multiple stakeholders. An Integrated Plantation System was selected as a case study for this research with participation from different stakeholders. Besides that, the Integrated Learning Management System and NIMSAD approaches were used to evaluate the proposed method. From the result, it is found that role-based goal modeling showed improvement in deriving high feasibility (five goals) and high adequacy (one goal) requirements for implementation. The integration of data elements indicates high complexity when multiple stakeholders interact with the same data element. In sum, role-based goal modeling can facilitate the process of analyzing and prioritizing requirements from multiple stakeholders in the early stages of the development process. |
