    4. 8th November 2005 EGOS Workshop 2005 Slide 4 Why Modelling? Improve Interoperability Platform Independent Standardise Data Types (Information Viewpoint) Standardise Interfaces / Services (Functional Viewpoint) Manage Complexity Abstraction for Clarity Overview of Interactions Ease of Reuse Improve Communication Visualisation via diagrams and relationships Share and discuss requirements, designs, solutions Enhance Robustness Auto-generate products (apply patterns, avoid manual mistakes) “Single Source“

    5. 8th November 2005 EGOS Workshop 2005 Slide 5 EGOSMF Concepts Based on RM-ODP Apply MDA and use UML Single Source Approach Platform Independent Model (PIM) Platform Mappings Support the Formal Definition of Requirements (Enterprise Viewpoint) Information / Data (Information Viewpoint) Interfaces / Services and Components (Functional Viewpoint) Protocols, Bindings, etc. (Communications Viewpoint) Deployment (Physical Viewpoint)
