Why are simple context models normally used alongside other models such as business process models?

Because context models do not show the types of relationships between systems, and process models describe the human and automated processes in which particular software systems are used — together they give a more complete picture

Because context models are only used in agile development, while process models are used in traditional development

Because process models replace context models once the system boundary is defined

Because context models are too complex and need to be simplified by process models

Correct Answer

Explanation

Context models alone do not show the nature of the relationships between the systems in the environment. Process models (such as UML activity diagrams) complement context models by describing the human and automated processes in which particular software systems are used, showing how the system fits into real workflows.
