What is described in a context model?
Answer: Context models show what lays outside the system boundaries by illustrating the operational context of a system. This involves working with system stakeholders to decide what functionality should be included in the system and what is provided by the system’s environment. Social and organisational concerns may affect the decision on where to position system boundaries. Context models normally show that the environment includes several other automated systems. However, they do not show the types of relationships between the systems in the environment and the system that is being specified. Architectural models show the system and its relationship with other systems.
