Creating and Using Impact Analysis

Impact analysis displays the interconnection of model elements using analysis graphs in a dynamic diagram. It therefore also visualizes the traceability of requirements, for example.

Impact analysis displays the interconnection of a model element through its relationships with other model elements using analysis graphs in a dynamic diagram. The model element's configurable analysis graph shows the current respective dependencies of a model element in an impact analysis diagram.

Impact analysis visualizes e.g. the traceability of requirements by displaying the corresponding relationships between a requirement and the system elements derived from it.

You can also visualize profile imports of system and partial model and also between profiles.

You can start a new impact analysis for a model element by selecting New Impact Analysis in the context menu. The model element is used as the start element. Alternatively, you can create an empty impact analysis diagram and drag a model element onto the diagram as the start element.

To increase the clarity of the analysis graph, you can:

• Identify the source and target nodes of a selected node
• Configure the content and appearance of the graph
• Determine the shortest path between selected nodes and display the distance from the first node
• Set certain nodes as end nodes in the graph

You can also implement a path analysis as well as analyze the way model elements are interconnected. This graphically visualizes the paths from a model element to one or more end elements.

You can save configuration for content and appearance so that you can reuse certain settings in other impact analysis diagrams.

An impact analysis diagram is dynamic and shows the analysis graphs of the start element at the current point in time after a refresh.
