Case Overview Architecture Goal & Challenge Architecture Goal & Challenge � Architecture Design Goal - ICOC architecture design for software solution development - Define software platform and identify core modules for business competency � Challenge - No reference architecture & concept only Architecture Process - Broad concept & lack of detail functionality - Rapid change of ubiquitous Technology - Ambiguous system role Architecture Driver - Seamless integration with external partner - System implement time is obscure 4 Arch.Process Architecture Design Approach Architecture Design Approach � Conceptual Architecture First. - Focus on system direction and scope with conceptual architecture � Based on SDS architecture design process with ADD - Phased architecting process for system of systems - ADD merged with SDS architecture design process � Data Flow Analysis as a supplementary technique - To derive system function - To define & verify role of internal module � Architecture designed according to the u-City road-map - Realistic feasible architecture for short-term - Additional long-term future architecture as a vision 5 �
Arch.Process SDS Architecture Design Process SDS Architecture Design Process � Designed for system integration project � Focused on system of systems � Phased approach from conceptual to actual design � Verification with executable architecture � Integrated with development methodology � Experience and reference based - but no reference & experience Data in this case.

Arch.Process Adopting ADD Adopting ADD � Why ADD - Rational process to define software architecture 1. Choose Module to Decompose � ADD 2. Refine Modules - Architecture design process - Quality scenario based a. Choose Arch. Drivers - Functional requirement Necessary - Providing architecture decisions b. Choose Arch. Patterns - Define interface to child modules c. Define Modules with Req. � ICOC Issues with ADD d. Define Interfaces - Insufficient functional requirement to instantiate module e. Verify & Refine Req. - System of Systems needs additional design effort 3. Repeat Step 2 due to many design issues 8 Arch.Process Tailored Architecture Design Process Tailored Architecture Design Process Business Scenario � Process & Requirement - SDS architecture design process to design application Initial Concept Reference Design architecture Development Decision Area - ADD merged Prototyping - Data Flow Analysis for ADD ADD compensation Conceptual Architecture Design � Input Architecture Decision Set - Prototyping Result.
