  7. ANSI/EIA-632 Process Requirements for Engineering a System 20Oct03 NDIA SED S3T2 RLEngwall

  8. Application Guidelines of ANSI/EIA-632 (What not How Oriented) • Decide Which of the 33 Processes Apply • Decide Which Requirements Apply for the Processes Selected • Establish Appropriate Policies & Procedures • Define Appropriate Tasks for Each of the Selected Requirements 20Oct03 NDIA SED S3T2 RLEngwall

  9. Application Guidelines of ANSI/EIA-632 (What not How Oriented) Continued • Establish Methods and Tools to Support Task Implementation • Representative Tasks Along With Their Expected Outcomes Are Provided in Annex C • Appropriate Processes Are Applied Recursively and Iteratively • Many Associate Tasks Are Concurrent And Highly Iterative And Have Interactive Dependencies That Lead To Alteration Of Previously Established Technical Requirements 20Oct03 NDIA SED S3T2 RLEngwall

  10. The ‘Newer’ 5000 MODEL User Needs & Technology Opportunities • Process entry at Milestones A, B, or C • Entrance criteria met before entering phase • Evolutionary Acquisition or Single Step to Full Capability (Program A B C FOC IOC Initiation) Concept & Technology Development System Development & Demonstration Production & Deployment Operations & Support Critical Design Review FRP Decision Review Concept Exploration Technology Development LRIP/OT&E Pre-Systems Acquisition Systems Acquisition Sustainment New 20Oct03 NDIA SED S3T2 RLEngwall

  11. Interdependency of DoD 5000 and ANSI/EIA 632 Processes 20Oct03 NDIA SED S3T2 RLEngwall

  12. Concept & Technology DevelopmentPhase A Technology Development Concept Exploration Concept Exploration Technology Development Enter:Validated & approved ICD • Activity:Paper studies of alternative solutions to the initial concept Exit:MDA selects preferred solution to be pursued Enter:Project leader understands solution as part of the integrated architecture and its DOTMLPF implications. • Activity:Technology development demonstrations Exit: Affordable increment of military-useful capability identified and demonstrated in relevant environment – normally can be developed for production within 5 years 20Oct03 NDIA SED S3T2 RLEngwall

  13. System Development & DemonstrationPhase B System Integration System Demonstration Critical Design Review System Integration System Demonstration Enter:PM has technical solution but has not integrated subsystems into complete system • Activities:System Integration of demonstrated subsystems and components. Reduction of integration risk. Exit: Demonstration of prototypes in relevant environment Enter:Prototypes demonstrated in intended environment • Activities:Complete development. DT/OT/LFT&E Exit:System demonstration in intended environment using engineering development models; meets validated requirements 20Oct03 NDIA SED S3T2 RLEngwall

  14. Production & DeploymentPhase C Full-Rate Production & Deployment LRIP FRP Decision Review LRIP Full-Rate Production & Deployment Enter:System matured for production • Activities:Low-rate initial production. IOT&E, LFT&E of production-representative articles. Establish full manufacturing capability. Exit:System operationally effective, suitable and ready for full rate production Enter:Beyond LRIP (ACAT I) and LFT&E reports (covered systems) submitted to Congress • Activities:Full rate production. Deploy system. Start support. Exit:Full operational capability; deployment compete 20Oct03 NDIA SED S3T2 RLEngwall

  15. Operations & SupportPhase Sustainment Disposal Sustainment Disposal Sustainment starts immediately upon fielding or deployment. • Activities: Maintain readiness and operational capability of deployed system(s). Execute operational support plans. Conduct modifications and upgrades to hardware and software. Measure customer confidence. Demilitarization & Disposal • Activities:Demilitarize and dispose of systems IAW legal and regulatory requirements, particularly environmental considerations. Use Defense Reutilization and Marketing Office support, as appropriate. 20Oct03 NDIA SED S3T2 RLEngwall

  16. EA/SD System Engineering Impact on Information Systems • Need toCapture System Information Once in Common Interoperable Format • Apply Distributed Tools for Collaborative Assessment & Optimization Including Pervasive Modeling & Simulation Throughout the System Engineering Product Life Cycle • Utilize ANSI/EIA-632 Technical Management and Technical Evaluation Processes Throughout the DoD Acquisition Process • A Broad, Extensible Representation Approach Is Key • Use EIA-927 Common Data Schema For Complex Systems 20Oct03 NDIA SED S3T2 RLEngwall
