3 6/17/2015 Background  Systems engineering needs and trends −Increasing focus on capability-based acquisition −Increasing focus on user/value −Increasing complex systems of systems Disproportional increase in complexity and interdependency Disproportional increase in needs for interoperability −Increasing COTS, Open Source, reuse, and legacy integration  New challenges in systems engineering and program management −Evolutionary, rather than revolutionary −Capability, rather than functionality −Lifecycle perspective, rather than acquisition focused −Heterogeneous, rather than homogeneous −Negotiation, rather than mandate

4 6/17/2015 Motivation for Net Centric SoS WBS  A step into continuing understanding of net centric SoS systems engineering and management −What is common, what is different? −New scopes and emphases Beyond traditional systems engineering considerations Emerging behaviors and risk from evolutional process −What is/belongs, what is/does not? −What works, what does not?  Time to step back and rethink −Systematic −Holistic −Mission and capability focused New Perspective Required for Net Centric SoS/FoS

5 6/17/2015 Motivation (cont.)  No standard or commonly-accepted WBS above system level −Traditional program/project management focuses on system and performance Build-to-spec, requirement-driven, waterfall-ish −Existing WBS constructs are system development focused – difficult to scale upward Development/acquisition centric, little attention to O&M Interpretabilities and independencies disregarded Enterprise context absent  Tool needed for integrated systems engineering and program management in net centric SoS programs −Facilitates the unification of SoS SE and PM −Emerging systems engineering method: Capability Planning  Basis for cost estimating

6 6/17/2015 Net Centric SoS WBS Goals  Provide −Standardized, yet flexible, prototypical WBS for net centric SoS engineering and management programs – a standard template to develop program- specific WBS −Reference model for SoS program management, systems engineering and cost estimating −Full SoS life cycle “cradle-to-grave” perspective and support −Systematic and holistic approach −Basic analysis framework for decision making −Clear, consistent and commonly accepted terminology definition −Tailorable and adaptable model

7 6/17/2015 Goals (cont.)  Integrate community-accepted best practices −General systems engineering and program management lifecycle −System-level WBS −Program and practice examples −Existing international standards ISO/IEC 15288: Systems Engineering – System Life Cycle Processes DoD : Operation of the Defense Acquisition System ANSI/EIA 632 Processes for Engineering a System MIL-HDBK-881: Work Breakdown Structure  Leverage leading development in net centric SoS systems engineering and processes, e.g., −Spiral development model −Capability-based acquisition −Capability planning and investment analysis practices

8 6/17/2015 Net Centric SoS WBS Scope  Target SoS/FoS type programs −With the charter to evolve mission capabilities of a SoS/FoS −Prototypical program lifecycle perspective  Consider −Program management and the supporting enterprise functions −Systems engineering and integration products −Development and O&M environments −Governance model  Capture three basic components of the SoS engineering and management practices −Systems Components and relationships Infrastructure −Processes Program management Systems engineering & integration Technology development Operations and support −People Management and acquisition authorities Teams Stakeholder community

24 6/17/2015 Program Office (cont.)  The supporting enterprise ensuring successful evaluation of the SoS capabilities based on mission −Provides Organizational or (DoD) MOTMLPF supports to projects −Provides infrastructure (e.g., IT) support  Lifecycle evolutionary perspective  Planning, managing, doctrine and oversight roles −Manages the three teams – Plan-Driven, IV&V and Agile  PM role in the stakeholder group includes a stakeholder liaison function −Emerging and important function for SoS/FoS programs  Reports to acquisition/service branch −To (commercial) general manager  System Integrator is a role, not an entity −It has four potential job descriptions simultaneously: On the three teams The systems engineering & integration/capability planning at the program level

25 6/17/2015 Outline  Background, motivation and goals −Relevant needs and trends in SoS system engineering and management −Development objectives  Basic foundations for the SoS WBS −Product-oriented structure −Scalable Spiral Model −Three-team construct  Net centric System of Systems (SoS) Program Work Breakdown Structure (WBS)  Implications and anticipated benefits  Conclusions

26 6/17/2015 Implications of Scalable Spiral Model  Evolution-oriented and capability-focused  Risk-driven and mission assurance  Good transition for the culture and legacy program management −Good talent pool for Plan-Driven Team  Less material-oriented deliverables from early spiral(s) −Architecture baseline more a focus  Different operational philosophy and management skill set −Build-to-spec will not work −“Best value” objectives −Cost, risk and schedule as independent variables  Requires forward-looking vision and a new breed of PMs

27 6/17/2015 Implications of Standardized SoS-Level WBS  Two prevalent structures: −Product-oriented −Activity-based  Integration with process-oriented and activity-based structures −Start with one structure at the top and integrate elements of the other at lower levels  Need to provide clear and consistent definition of terms −Or potential risks of double-counting −Need for glossary and data dictionary  Possible different organizations for different purposes −Different development models  Less clear boundary for scope and division of responsibility −Are the day-to-day operational activities (and personnel) “sunk cost”? −Whose responsibility is it to establish doctrine, program office or larger enterprise?  Implications to cost estimating  Linkage to other architecture products

28 6/17/2015 Anticipated Benefits  Provides a reference model for SoS/FoS engineering and management  Defines a common set of terminology related to SoSs  Enables visibility and insights into unique issues related to SoSs  Provides a holistic view for SoS engineering and program management, particularly in terms of −Interoperability −Complexity and interdependency −Ownership and governance model −Conflict management −Decision framework  Facilitates further understanding of the −Effort and cost in acquiring and owning an SoS −Methodology that can be applied to estimate this cost  Promotes the unification of systems engineering and project management for SoS −Linkage between architecting/engineering activities to the economic effect

29 6/17/2015 Outline  Background, motivation and goals −Relevant needs and trends in SoS system engineering and management −Development objectives  Basic foundations for the SoS WBS −Product-oriented structure −Scalable Spiral Model −Three-team construct  Net centric System of Systems (SoS) Program Work Breakdown Structure (WBS)  Implications and anticipated benefits  Conclusions

30 6/17/2015 Conclusions To Date  General systems engineering principles and project management practices do apply to net centric SoS  Traditional system-oriented WBS construct is inadequate, and there are added ingredients in WBS for net centric SoS, from −Added complexity −Different scope, objectives and strategy −Different environment  Two different acquisition focuses: −System: functionality −System of systems: capability  And, therefore, two different development strategies: −System: waterfall −System of systems: scalable spiral  Not a complete WBS, but a step towards that direction  A lot to learn, and more to explore…
