Because we are using the same UML concepts (except for slightly different stereotypes) to model a business that we use to model a system, we can use the same tools. Rational Rose provides all we need to produce the visual models described earlier.
Just as in software engineering, you can use the Rational RequisitePro tool to capture textual aspects of the business models and to maintain dependencies between and among model elements in different models.
To generate and maintain documentation of the models, you can use the Rational SoDA tool.
