  1. Enterprise Software Architecture Modelling Tool Model-One

  2. Model-One

  3. Model-One Introduction • Flash-based enterprise software architecture modelling tool • Has visual tools for senior managers • Supported by detailed data for technologists • Different views show architecture changes over time • Driver for change • Shows areas of system redundancy • Shows potential alternatives

  4. Model-One Introduction • Architecture defined by: • Logical Components • Software Systems • Services (in a Service Oriented Architecture) • Small footprint – typically < 1 Mb • Portable – runs on any Flash-enabled browser • No database or web server required for distribution

  5. Model-One Methodology System Owners Adobe Flex Microsoft Excel Data gathering XML file produced Flash file produced Direct distribution Publish to internet / intranet Flash-enabled Web Browser End Users Web Server

  6. Model-One Methodology • Initial data gathering phase • Data held in Excel and transformed into XML • XML data read by Adobe Flex application • Flex application compiled into Flash object • XML data encapsulated within Flash object • Flash file distributed as required

  7. Model-One Architecture SYSTEM 1 supports COMPONENT 1 TRADE ENTRY S1 COMPONENT 3 TRADE PRICING offers provides to requested by COMPONENT 2 REPORTING requested by provides to S2 offers supports SYSTEM 2

  8. Model-One Architecture • Based around Service Oriented Architecture (SOA) • Logical components describe aspects of the business model • Each logical component offers a number of services • These services are requested by other components

  9. Model-One Architecture SYSTEM 1 SYSTEM y SYSTEM x S1 offers provides S2 to System ... provides S1 to System 2 SYSTEM 2 S2 requests S1 from System 1 offers

  10. Model-One Architecture • Systems support various components • Implied service relationships between systems because of components • Actual service relationships between systems also stored

  11. Model-One Logical View

  12. Model-One Logical View • Default starting view for Model-One • Typically 20-25 logical components • Components can be grouped as required • Actors (non-technology components) show people, teams, external groups • Tooltips show detailed component descriptions • Components can be clicked to show detailed information

  13. Model-One Component Details

  14. Model-One Component Details • Shows detailed information about logical component (can be altered as required) • Services offered by the component • Services provided by the component to other components • Services requested by the component from other components

  15. Model-One Component Details

  16. Model-One Component Details • Shows systems supporting this component • Filters available by system or timeline view • Can see which services offered by the component are actually used by the systems

  17. Model-One System View

  18. Model-One System View • Each logical component is supported by one or more software systems • Immediately shows areas of redundancy where there are many systems supporting the same logical components • Systems colour-coded to show fate across time • Multiple user-defined views available to show architecture changes over time

  19. Model-One System Details

  20. Model-One System Details • Like logical components, each system offers, provides and requests services • Unlike logical components, these are actual services • This can validate the notional services offered by the components

  21. Model-One System Details

  22. Model-One System Details • Impact tab shows what would happen if the selected system is demised • In this case, ALGO provides a number of services to MUREX • If one service is selected, then any alternative systems that can provide the same service will be shown on the right

  23. Model-One System Details • In this case, Prism offers the “Create Limits” service, so this system may be used as an alternative to support Murex if ALGO is demised

  24. Model-One System Details • However, for the “RM Functions – UI” service, there is no alternative system • This can drive analysis and bring out issues much earlier in the development cycle

  25. Model-One Process View

  26. Model-One Process View • Business process modelling view • Business scenarios with steps defined • Each step can be linked to a service within the model • Acts as validation for the model and a useful training tool

  27. Model-One Process View • Clicking on each step highlights the components and services used

  28. Model-One Process View • As each step is selected, the previously-used components remain active

  29. Model-One Functional View

  30. Model-One Functional View • Each system can be linked to two functional groups (user-defined) • This allows a system architecture diagram to be derived

  31. Model-One Links View

  32. Model-One Links View • Dynamic visualisation of system-service connections • Nodes (systems or services) rotate and move when selected • Clearly shows related systems and how they are linked

  33. Summary • Agile development methods mean user-requested changes (new data or visualisations) can be added easily • Small footprint and use of Flash ensures ease of distribution • Blends clean information visualisation with underlying data power • Clear driver for change projects
