10.6. Runtime View#
The runtime view describes concrete behavior and interactions of the system’s building blocks in form of scenarios from the following areas:
important use cases or features: how do building blocks execute them?
interactions at critical external interfaces: how do building blocks cooperate with users and neighboring systems?
operation and administration: launch, start-up, stop
error and exception scenarios
Remark: The main criterion for the choice of possible scenarios (sequences, workflows) is their architectural relevance. It is not important to describe a large number of scenarios. You should rather document a representative selection.
You should understand how (instances of) building blocks of your system perform their job and communicate at runtime. You will mainly capture scenarios in your documentation to communicate your architecture to stakeholders that are less willing or able to read and understand the static models (building block view, deployment view).
There are many notations for describing scenarios, e.g.
numbered list of steps (in natural language)
activity diagrams or flow charts
BPMN or EPCs (event process chains)
See Runtime View in the arc42 documentation.
