Health care domain faces an era of unprecedented pressure in order to improve the quality and effectiveness of care. Subsequently, Hospital Information Systems (HIS) have become mandatory in order to improve the quality of both health care and managerial processes, while simultaneously reducing their cost. However, due to complex nature of HIS, variety of end users and professional disciplines related to the production process of care, stakeholders require an in-depth analysis of requirements. This paper proposes a novel approach for modeling HIS requirements based on the System of Systems (SoS) paradigm. The language used is SysML due to its vocation to be a modeling language dedicated to complex systems. The billing system serves as an experiment for modeling and requirements association.
