Chapter 2 : Approach to define Entities
Define Enterprise scope: definition at Group level, Company level or lower level?
Define Entity Domains: Actors, Products, Contracts, Organization,
Look for existing Glossaries: internal or external glossaries (from inter professional initiative or Package provider)
Define links between Entities: relation (“has”) and inheritance (“is”). Progressively build the Entity Model: Entities are defined altogether.
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
