University of Southern California Center for Systems and Software Engineering 5 ARB Session Outline DCR similar format to FCR, different focus: Less time for OCD, Prototype More time for Architecture, Plans General rule on focus: emphasize your projects high risk areas –At FCR (in most cases) this will involve establishing the operational concept (including system analysis) –At DCR (in most cases) this will involve the system design and development plan (especially schedule)

University of Southern California Center for Systems and Software Engineering 4 ARB Review Success Criteria FCRDCR For at least one architecture, a system built to arch. will: Support the Ops Concept Satisfy the Requirements Be faithful to the Prototype Be buildable within the budgets and schedules in the Plan Show viable business case Key stakeholders committed to support Foundations Phase (to DCR) For the selected architecture, a system built to the arch. will: Support the Ops Concept Satisfy the Requirements Be faithful to the Prototype Be buildable within the budgets and schedules in the Plan All major risks resolved or covered by risk management plan Key stakeholders committed to support full life cycle

University of Southern California Center for Systems and Software Engineering Commitment Review Success Criteria TRR / OCR Show value Product works as expected (or not with noted exceptions) Product will help users do job Show quality development e.g. relevant parts of your IOC documentation Process Show sustainability e.g. support requirements/plans Transition plan & status Show confidence that product is/will be ready to be used e.g. Transition plan & status See also value Determine whether client needs anything further to ensure successful Transition and Operation Changes in priorities for remaining features? Changes being made to operational procedures? More materials needed for training? Changes in system data or environment we should prepare for? Anyone else who should experience CCD? CCD

University of Southern California Center for Systems and Software Engineering 8 Development Commitment Review (DCR) More formal, with everything appropriate specifically tracing upward and downward No major unresolved issues or items, and closure mechanisms identified for any unresolved issues or items No more TBD's There should no longer be any "possible" or "potential" elements (e.g., Entities, Components, …) Persistant Information Classes with proper multiplicities No more superfluous, unreferenced items: each element (e.g., Entities, Components, …) either should reference, or be referenced by another element. Items that are not referenced should be eliminated, or documented as irrelevant

University of Southern California Center for Systems and Software Engineering 9 DCR ARB Session Overview Less time for OCD, Prototype More time for Architecture, Plan Fine-tuning based on FCR ARB experience Focus on changes since FCR Emphasize material that is relevant to 577B (or to end of class) Risk management still fundamental

University of Southern California Center for Systems and Software Engineering TRR Presentation Summary Specific requirements for your presentation: –Your product! i.e., fully working IOC version –Salesman-like discussion of your project’s usefulness Base on your business case, etc Why is system going to be really great for customer –Transition issues & transition plan if you delivered your product how did it go? –(you should have by presentation) If not, when? –Support issues How will you support product, once deployed? –E.g. next term, for instance –OK to say that »You will never touch it ever again »Everything’s up to customer
