Module Overview
Use activity diagrams to show business workflow, decision points, handoffs, and exceptions.
Use class diagrams to show core entities, relationships, and responsibilities.
Explain when a process view is useful and when a domain model is required.
Use diagrams to align business, architecture, and delivery language.
Theory
Activity diagrams help explain what happens across a process. Class diagrams help explain the important concepts and relationships that the solution must understand. Together they reduce ambiguity between business language, system behaviour, and data structure.
Workshop
Model a patient onboarding or service request workflow, then identify the core domain concepts that must be represented consistently across systems.
Create one activity diagram and one simple class diagram for the selected workflow.
Explain how your process and domain diagrams reduce delivery ambiguity.
