  2. Introduction • This presentation will show a commercial example of applying MBASE principles in industry • The RAPID Value™ methodology is used to conceive and develop e-commerce solutions • initially developed at C-bridge, a USC-CSE affiliate • RAPID Value™ is closely allied with USC MBASE and the Rational Unified Process (RUP) • All are modern, risk-driven iterative lifecycle approaches to developing software systems. • the major lifecycle phases of all 3 methods can be mapped one-to-one • C-bridge extended the lifecycle concepts to the business world, and elaborated the best practices to rapidly deliver Internet systems

  7. RAPID Value™ Delivery Guiding Principles • Business Solution Focused • Risk-driven Iterative Process • Architecture-first • Timeboxing • Joint Application Development • Demonstration-based Approach • Project Communication using the Internet -Project Center and Knowledge Bank • Object Oriented Analysis, Design and Development

  8. RAPID Value™ Project Approach Iteration Scope, Listening, Delivery focus Lines of readiness Are we ready for the next step? Define Design Develop Deploy Build 1 Build 2 Production Pilot Program Release to Test Beta Program Generate Use Cases Stabilization Build Identify System Actors Object Domain Modeling Polish Design, Build Plan Document Business Processes Define basic development strategies Object Interactions, System Services Detailed Object Design, Logical Data Model

  9. Process Milestones • Process milestones are common anchor points around which plans and budgets are organized • milestones also represent “lines of readiness” • RAPID Value™ contains the following milestones for anchoring product elaboration • Business Vision (BV) • identify what to change, what to change to, and how to make the change happen • unique to the C-bridge RAPID Value™ process • Life Cycle Objectives (LCO) • establishing a sound business case • Life Cycle Architecture (LCA) • commit to a single architecture and elaborate it to cover all major risk sources • Initial Operational Capability (IOC) • commit to transition and support operations

  10. Milestone Element Life Cycle Objectives (LCO) Life Cycle Architecture (LCA) • Top-level system objectives and scope • - System boundary • - Environment parameters and assumptions • - Evolution parameters • Operational concept • - Operations and maintenance scenarios and parameters • - Organizational life-cycle responsibilities (stakeholders) • Elaboration of system objectives and scope of increment • Elaboration of operational concept by increment Definition of Operational Concept • Exercise key usage scenarios • Resolve critical risks • Exercise range of usage scenarios • Resolve major outstanding risks System Prototype(s) • Top-level functions, interfaces, quality attribute levels, including: • - Growth vectors and priorities • - Prototypes • Stakeholders’ concurrence on essentials • Elaboration of functions, interfaces, quality attributes, and prototypes by increment • - Identification of TBD’s( (to-be-determined items) • Stakeholders’ concurrence on their priority concerns Definition of System Requirements • Choice of architecture and elaboration by inc. • - Physical and logical components, connectors, • configurations, constraints • - COTS, reuse choices • - Domain-architecture and architectural style choices • Architecture evolution parameters • Top-level definition of at least one feasible architecture • - Physical and logical elements and relationships • - Choices of COTS and reusable software elements • Identification of infeasible architecture options Definition of System and Software Architecture • Elaboration of WWWWWHH* for Initial Operational • Capability (IOC) • - Partial elaboration, identification of key TBD’s for later increments • Identification of life-cycle stakeholders • - Users, customers, developers, maintainers, interoperators, general public, others • Identification of life-cycle process model • - Top-level stages, increments • Top-level WWWWWHH* by stage Definition of Life- Cycle Plan • Assurance of consistency among elements above • - via analysis, measurement, prototyping, simulation • - Business case analysis for requirements, feasible architectures Feasibility Rationale • Assurance of consistency among elements above • All major risks resolved or covered by risk management plan Description of LCO/LCA Milestones (Risk-driven level of detail for each element) *WWWWWHH: Why, What, When, Who, Where, How, How Much

  14. Types of RAPID Value™ Delivery • RAPID Value™ Delivery • normal duration is 24 weeks • this presentation describes the normal process • RAPID Value™ Delivery Fast Track • 16 weeks

  15. Critical RAD Success Factors • Prioritized requirements • A reasonable “ballpark” schedule estimate • Software design for ease of contraction • Schedule tracking for midcourse corrections • Better and fewer people • Teambuilding and shared vision among all stakeholders • Co-location • Learning, metrics, continuous improvement • Prepositioning • domain engineering, architecting • reuse everything: plans, specs, class libraries, middleware, tests, manuals • people and teambuilding, tools and facilities

  16. Timeboxing • Traditionally, size (~functionality) is the independent variable for software development while cost and schedule are dependent on it • Timeboxing treats schedule time as the independent variable (“design-to-schedule”) • development must be accomplished within a fixed timeframe • functionality descoping takes place to ensure that timebox is met

  17. RAPID Value™ Delivery -Diagnosis deliverables used to map Delivery methodology for implementation -Define stage will produce specific line items and use-cases based on business strategies -Design customized system elements with our proprietary technical frameworks -Complex IT Architecture installed for deployment -The Delivery methodology is iterative, meaning that we continuously refine our initiatives based on requirements

  18. Define Objective: develop a prototype of the user interface, define links to external systems, and document business use cases and workflow.
