4. Copyright © 2003 Encapsule Systems, Inc. Languages Have Limitations Conceptual Requirements Subsystems Subsystem Interactions Interconnection Networks Data Flow Design Patterns Libraries Objects / Assemblies Programming Languages Expressive power of our programming languages starts to fail us No problem – good process, good tools

5. Copyright © 2003 Encapsule Systems, Inc. The Software Quandary Conceptual Requirements Subsystems Subsystem Interactions Interconnection Networks Data Flow Design Patterns Libraries Objects / Assemblies Programming Languages How to we efficiently describe the product requirements?

6. Copyright © 2003 Encapsule Systems, Inc. Software Design Today Conceptual Requirements “Pseudo” Design Spec. Subsystems Subsystem Interactions Interconnection Networks Data Flow Σ Programming Language Break a big design problem into smaller design problems that you think can be solved… Best effort

7. Copyright © 2003 Encapsule Systems, Inc. Software Production Today Product? Subsystems Subsystem Interactions Interconnection Networks Data Flow Design Patterns Libraries Objects / Assemblies Programming Languages Extremely difficult code that must be written by hand… No problem

8. Copyright © 2003 Encapsule Systems, Inc. Did We Succeed? Product? Test against design specification OK? $ Back to production $ Alpha test Beta release OK? $$$ Back to design $$$ NO

33. Copyright © 2003 Encapsule Systems, Inc. Aurora™ Process Roles  Requirements specification (CSDL Circuit creation)  Non-technical task performed by anyone  Application architecture (CSDL Module definitions)  Senior/Principle Design Engineering staff  Application Implementation (CSDL Processor definitions)  Junior/Senior Production Engineering staff

34. Copyright © 2003 Encapsule Systems, Inc. Aurora™ Platform Benefits  Lower development costs  Decouples requirements & technology  Decouples specification & implementation  Top-down holistic process  Superior technology re-use  Early testing = fewer defects  Clearly defined maintenance / migration

35. Copyright © 2003 Encapsule Systems, Inc. Modeling Tools Today  Leverage OO programming concepts  Good for OO (C++/Java) components  Poor for complex interconnect nets  Function of OO programming languages  Adoption problems (10% adoption) Aurora™ used in addition to, not in place of current tools.

36. Copyright © 2003 Encapsule Systems, Inc. Where Can This Be Useful? Potential markets for Aurora™:  Enterprise software  Multi-billion dollar space  Desktop software  Multi-billion dollar space  Development tools  Multi-billion dollar space  Embedded systems  100’s of millions dollars

37. Copyright © 2003 Encapsule Systems, Inc. How to Play? Business model selection:  Create and sell shrink wrapped product?  Compete against existing players  License core technology?  Partner with existing players  Sell integration services?  Use tool internally for competitive advantage  Operate as an Application Service Provider (ASP)  Give the tool away / sell models

38. Copyright © 2003 Encapsule Systems, Inc. Challenges  Short Term  Extensive market research required  Product completion  Limited funding  Long Term  Significant marketing effort  Evangelism + customer education  Ongoing fund raising efforts
