Integration of Organisational Models and UML Use Case

The fundamental step in systems implementation is requirements gathering. This step is categorized into early phase requirements elicitation and systems modelling. Requirement elicitation involves gathering stakeholders’ intentions, goals, rationale and organizational context that can be modelled with agent-oriented conceptual modelling such as i*. On the other hand, systems’ modelling is portraying abstract version of interaction among inter-related components within a whole system via UML languages such as Use Case diagrams. The co-evolution of Agent-Oriented conceptual model such as i* and Use Case Diagrams aims to close the gap of capturing organizational requirements and system requirements. However, changes made in i* must be reflected in the Use Case diagram to ensure consistency in requirements. Therefore, this paper proposes a methodology supporting the co-evolution of these two otherwise disparate approaches in a synergistic fashion.
