Launching an Impact and Lineage Analysis

You analyze the impact of a change to your model from the Impact and Lineage Analysis dialog box, which lets you review your analysis through:

1. Open an impact and lineage analysis in any of the following ways:
   
   

   • Select an object in the Browser or in the diagram and press ctrl+F11.

   • Select one or more objects in the diagram and select Tools > Impact and Lineage Analysis.

   • Right-click an object symbol in the diagram and select Edit > Impact and Lineage Analysis.

   • Right-click an object entry in the Browser and select Impact and Lineage Analysis.

   • [when deleting an object] Click the Impact button on the Confirm Deletion dialog box.

   • Open an object's property sheet, click the Dependencies tab, and then click the Impact Analysis button.

2. [Optional] Enter a name for your analysis result. This will be the name of the generated model (see Reviewing an Analysis in an IAM Model).
3. Select an impact rule set for your analysis. You can choose one of the following predefined rule sets:
   
   

   • Conceptual Impact Analysis – to restrict the analysis to objects impacted by modeling changes on the initial object, such as a modification on a requirement definition.

   • Data Impact Analysis – to identify the use, if any, of a value contained in the initial object.

   • Delete Impact Analysis – [default when deleting an object] to restrict the analysis to objects that are directly impacted by the deletion of the initial object.

   • Global Impact Analysis – [default when not deleting an object] to identify all the objects that depend on the initial object.

   • None – no impact rule set is selected.

4. Select a lineage rule set for your analysis. You can choose one of the following predefined rule sets:
   
   

   • Conceptual Lineage Analysis – to justify the modeling existence of the initial object, and ensure it fulfills a well-identified need.

   • Data Lineage Analysis – to identify the origin of the value contained in the initial object.

   • Global Lineage Analysis – [default when not deleting an object] to identify all the objects that influence the initial object.

   • None – [default when deleting an object] no lineage rule set is selected.

5. [optional] Click the Properties tool next to each rule set to review it (see Editing analysis rules).

   The analysis displays in the Impact and Lineage tab of the dialog box (see Reviewing an Analysis in Preview). You can click the Generate Diagram button to graphically view the analysis in its default diagram (see Reviewing an Analysis in an IAM Model).
