s. In the diagram nodes are interactions of sequence diagrams, and the edges show the order in which these interactions occur. You can also use an interaction overview diagram to deconstruct a complex scenario that would otherwise require multiple if-then-else paths to be illustrated as a single sequence diagram.
Most of the notation for interaction overview diagrams is the same for activity diagrams. For example, initial, final, decision, merge, fork and join nodes are all the same. However, interaction overview diagrams introduce two new elements: interaction occurrences and interaction elements.
