Goal-Oriented Strategic Modelling for Cancer Care in Systems of Systems Context Using the i* Framework

Cancer Care is considered as a System of Systems (SoS) which results from the collaboration of a set of independent socio and technical constituent systems, largely driven by stakeholders’ needs and goals at multiple levels in a cancer care organisation taking into consideration SoS high-level goals and the constituent systems-level individual goals. It’s challenging to manage these goals specially in such complex large-scale SoS arrangement. However, Goal-Oriented Requirements Engineering (GORE) is considered a promising approach in SoS context to adopt in order to identify, model and manage goals achieved by the overall SoS and its constituent systems. This paper is aimed at investigating the implications of using GORE approaches, and in particular the i* framework to model Cancer Care goals in SoS context. We propose a new process to extract i* elements and concepts from existing user documentation, a "Goals Referential Integrity (GRI)" model that is aimed at maintaining the integrity and consistency of both the SoS-level goals and the constituent systems-level goals, and a proposed i* Cancer Care Goal-Oriented model in Systems of Systems context applied to the Admission, Discharge, and Transfer (ADT) cross-sectional organisational processes of King Hussein Cancer Centre in Jordan.
