UML activity diagrams?
- UML activity diagrams are well suited to model action sequences.
- It depicts the control flow between activities or actions.
- In case of a sequential progression of actions, a subsequent action is executed once every precedent action terminates.

This is depicted as a circle with a cross or ‘X’ in the circle. This node indicates the termination of a control flow.
Merge of Alternative control flows
This is depicted as a diamond with two input control flows. This indicates a point in the action sequence steps where two control-‐flows meet and proceed to the next step as the same control flow.
