Main Description

Overview 

The steps in this tool mentor match those in the task. Links to topics in the Rational XDE (TM) online Help are marked with helpbook icon.

This tool mentor assumes that a Use-Case Model has already been created in accordance with the XDE Model Structure Guidelines.

The following steps are performed in this tool mentor:

Find Actors

After finding the actors, record your results as follows:

  1. Open the Use-Case Model.
  2. Navigate to a package where actors are to be captured. See Rational XDE Model Structure Guidelines.
  3. Create a diagram to capture actors, selecting use-case diagram for the diagram type. Reference: helpbook iconAdding Diagrams.
  4. Add actors to the diagram. See helpbook iconAdding Shapes to Diagrams.
  5. Annotate each actor with a brief description. See helpbook iconDocumenting Model Elements .

Find Use Cases

After finding use cases, record your results as follows:

  1. Navigate to a package in which use cases are to be captured. See Rational XDE Model Structure Guidelines.
  2. Create a use-case diagram to capture use cases. Reference: helpbook iconAdding Diagrams.
  3. Add use cases to the diagram. See helpbook iconAdding Shapes to Diagrams.
  4. Provide a brief description and the outlined flow of events. This can be initially annotated on the model element. (See helpbook iconDocumenting Model Elements .) Alternatively, you can use the RUP-provided template for Artifact: Use Case and attach it to the use case in the model. See helpbook iconLinking External Files to Model Elements .

Describe How Actors and Use Cases Interact

Describe the interaction between actors and use cases by following these steps:

  1. Add previously created actors to the use-case diagram containing the use cases. See helpbook iconAdding Shapes to Diagrams .
  2. Add communicates associations between actors and use cases. (See helpbook iconAdding Association Relationships .) If an association is navigable in only one direction, select a directed association, click the consumer shape first, and then click the supplier shape.
  3. Optionally, describe the association. See helpbook iconDocumenting Model Elements .
  4. Optionally, add multiplicity of a role. See helpbook iconSpecifying Multiplicity in Association Ends .

Package Use Cases and Actors

Organize actors and use cases in packages.

Reference: helpbook iconGrouping Model Elements in Packages.

Present the Use-Case Model in Use-Case Diagrams

For the purposes of this tool mentor, it is assumed that diagrams have been created as actors and use cases are identified. See earlier steps for guidance on use-case diagramming using Rational XDE.

Develop a Survey of the Use-Case Model
