Overview

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:

Identify Common Requirements  To top of page

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:

  1. Open the Use-Case Model.
  2. Navigate to the package containing the use cases. See Rational XDE™ Model Structure Guidelines.
  3. 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.
  4. 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.
  5. Add relationships between the use cases. The following sections describe how to add each kind of relationship.
  6. Document each relationship. See .

Create additional use-case diagrams and package them as needed to manage the complexity. See and .

Establish Generalizations Between Actors To top of page

  1. Open the Use-Case Model.
  2. Navigate to the package containing the actors. See Rational XDE Model Structure Guidelines.
  3. In Tool Mentor: Finding Actors and Use Cases Using Rational XDE, a diagram was created to capture all the actors. Open this diagram.
  4. 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.
  5. Add generalizations between actors. See .
  6. Optionally document each generalization relationship. See .
