Show how the system executes, the dynamics of the system, its behavior in terms of its building blocks.

The following types of scenarios might be relevant for you:

• The most important use cases, features or functions
• System startup
• The systems´ behavior on its most important external interfaces
• The systems´ behavior in important error or failure situations

It’s important that the runtime view shows which building block is responsible for what activities or functions within the system. Therefore the mapping of (static) blocks to activities, process steps, functions or other dynamic elements is important.
