Chapter 2 : Approach to define Entities
- Define Enterprise scope: definition at Group level, company level or lower level?
- Look for existing Glossaries: internal or external glossaries (from inter professional initiative or package provider)
- Define links between Entities: relation (“has”) and inheritance (“is”).
- Define Descriptors: Entities with simple life cycle (like Person, Address, Organization, …), also called referentials
- Define Operations: Entities which represent Inputs (they must be prepared then executed).
- Define Multi Execution Processes: Entities with complex life cycle which represent the more complex Activity of the Enterprise
