Before you can perform an impact analysis on the designs
in your project area, you must first create an impact analysis configuration.
Before you begin
You must be logged in to the product and have a project dashboard
open.
About this task
Impact analysis diagrams are driven by impact analysis configurations.
Configurations can limit the linked artifacts that are included in
an impact analysis diagram. For example, a configuration can specify
the following limitations:
- Restrict links to only upstream or downstream artifacts.
- Upstream links are those that lead to the target artifacts in
an impact analysis.
- Downstream links are those that lead away from the target artifacts
in an impact analysis.
- Restrict the depth of each link followed.
- Restrict the kinds of links that are followed.
- Restrict the kinds of artifacts that are included in the diagram.
Procedure
- On the project dashboard, in the Analysis menu,
click .
- Optional: In the editor, click in the title
field and type a name for the new configuration.
- Optional: On the General tab,
enter a description of the impact analysis configuration.
- To specify the depth of the impact analysis, complete the
following steps:
- To include artifacts that are upstream from the target
artifact, specify the number of levels to check or select the Unlimited check
box.
- To include artifacts that are downstream from the target
artifact, specify the number of levels to check or select the Unlimited check
box.
By default, both Unlimited check boxes
are selected, which means that all links lead to and from the target
artifact will be included in an impact analysis.
- On the Filters tab, define the filters
to apply to the impact analysis configuration.
- To exclude the artifact types and list types specified
in the corresponding sections, select the Ignore selected
artifacts and links check box. To include only the artifact
types and link types listed, clear the Ignore selected
artifacts and links check box.
- To limit the impact analysis to specific types of artifacts,
in the Filtered Artifacts section, click the Add icon.
- In the Add Filter (Artifact) window,
select a domain and a value from the respective lists and click Add. The new filter is displayed in the Artifact
Type list.
- To limit the impact analysis to specific types of links,
in the Filtered Links section, click the Add icon.
- In the Add Filter (Link) window,
select a domain and a value from the respective lists and click Add. The new filter is displayed in the Link Type list.
- On the Project Linking tab, in the Cross
Domain Links list, select the types of links to include
in the impact analysis.
- Click Save. The new impact analysis
configuration is included in the list of available configurations.
