Overview
The steps in this tool mentor match those in the task. Links to topics in Rational XDE™ online Help are marked with
.
This tool mentor assumes that a Use-Case Model, populated with actors and use cases, has already been created by
following the steps outlined in Tool Mentor: Finding Actors and Use Cases Using Rational XDE.
This tool mentor consists of the following steps:
Sharing of common use cases is accomplished by adding relationships between existing use cases or creating new use
cases. To do this, follow these steps:
-
Open the Use-Case Model.
-
Navigate to the package containing the use cases. See Rational XDE™ Model Structure Guidelines.
-
In Tool Mentor: Finding Actors and Use Cases Using Rational XDE, a
use-case diagram was created containing all the use cases and actors. Navigate to this diagram.
-
Refactor the use cases, creating new ones as applicable. The procedure for creating new use cases using Rational
XDE is described in Tool Mentor: Finding Actors and Use Cases Using Rational XDE.
Detailing these new use cases is described in Tool Mentor: Detailing a Use Case Using Rational XDE.
-
Add relationships between the use cases. The following sections describe how to add each kind of relationship.
-
Document each relationship. See Documenting Model
Elements .
Create additional use-case diagrams and package them as needed to manage the complexity. Reference: Adding Diagrams
Grouping Model Elements in Packages

-
Open the Use-Case Model.
-
Navigate to the package containing the actors. See Rational XDE Model Structure Guidelines.
-
In Tool Mentor: Finding Actors and Use Cases Using Rational XDE, a
diagram was created to capture all the actors. Open this diagram.
-
Refactor existing actors, and create new actors as applicable. The procedure for creating actors is explained in Tool Mentor: Finding Actors and Use Cases Using Rational XDE.
-
Add generalizations between actors. See Adding
Generalization Relationships .
-
Optionally document each generalization relationship. See Documenting Model Elements
.

Diagrams .
There is no Rational XDE specific guidance for this step.
