These diagrams provide detailed visual representations of various business processes within the Dealer Management System. They help in:
1. Understanding workflow sequences
2. Identifying process dependencies
3. Visualizing decision points
4. Mapping system interactions
5. Documenting business rules
6. Training new team members
7. Process optimization
8. Troubleshooting issues

The diagrams use different Mermaid syntax types (graph, sequence, state, er) to best represent each process type and relationship.
