Identify common business requirements
Understand the requirements that are common to more than one business use case, or that describe optional or
exceptional behavior. Understand. Review each completed business use case and note any commonality or exceptional behavior
that's not tightly coupled with the rest of the business use case. |
Organize business requirements in business use cases
Move the identified business requirements to more appropriate business use cases to make understanding and
managing the business use cases easier.
Use <<include>> and <<extend>> relationships between business use cases to maintain the
appropriate scenario flow across use cases.
|
Establish generalizations between actors
Model common characteristics between actors. Write a brief description of the actor-generalizations, and include them
in use-case diagrams for further clarification. See Guideline: Using Actor Generalization for more information.
|
Organize the business use-case model into packages
If the business use-case model has a large number of elements, consider organizing the business use cases into use-case
packages. Focus on making the business use cases easy to locate for someone unfamiliar with the model. |
Evaluate results
Discuss the incorporation of include-, and extend-relationships with the customers and stakeholders, and assure they have a
clear understanding of the system based on the updated business use case model. |
