Topics to Consider

You may want to examine these additional topics:

• Collaboration diagrams—Another type of interaction diagram (like sequence diagrams) where the model elements are the center of focus instead of focusing on the message flows (as in sequence diagrams).

• Generalization association—An association that indicates that one thing is a “type of” another thing (e.g., a truck is a type of vehicle). How might this be used with business actors?

• How might each of your business model diagrams be affected if a corporate business goal was for your business to be the low-cost supplier versus being the top service provider?

• You can find many of the concepts in this chapter (e.g., business use case model, business analysis model) further elaborated upon in the Rational Unified Process. [RUP2]
