  5. SOA Architecture Goals • Deliver SOA systems designs that industry can use to develop/migrate to functional services that will easily integrate into the DCGS-A whole • Ensure that the SOA system designs trace to and are relevant to the DCGS-A mission requirements and priorities • Drive towards an objective DCGS-A system characterized by: • Mission agility: Rapidly react to changing mission needs by assembling the required services • Support the new TPPU process • Platform independence: update technology more easily • Modular approach: accelerates systems development and evolution 19 MAY 2006

  15. DCGS-A SOA Lessons (1) – SOA is the path, NOT the end goal • SOA as the long-term, “to-be” solution is not good enough • Often used as excuse to maintain status quo! • Rather, use SOA as the migration path to the future • Define incremental roadmap for “capability over time” • Service-enable legacy capabilities as a start • Target “low hanging fruits” • Develop stable interface specifications to mitigate risks • Regular, frequent releases of deliverables (we delivered every month) • Develop a Reference Implementation • Show value early! 19 MAY 2006

  16. DCGS-A SOA Lessons (2) – SOA Is Not Just About Technology • Don’t underestimate the organizational barriers to change • Choose a small but powerful group to build initial deliverables • Identify a wide audience to review and provide feedback • Help client understand how to utilize the SOA deliverables • Communications and outreach (socialize the deliverables) • Get senior level championship • Solve client’s immediate problems to build trust and relationship • Avoid semantic / terminology conflicts; use the client’s language • “What is the business model?” 19 MAY 2006

  17. DCGS-A SOA Lessons (3) – Put the User Back in SOA • SOA needs a user interface! • Needs to show how it results in improved user experience • Demonstrate through real-world scenarios • SOA is about enablement, not control • User-definable processes / workflows • User-specified data scope (e.g., AOI and time range) • Trace architecture decisions to user / operational priorities • Have a clear story on how the SOA approach provides value to the user 19 MAY 2006

  18. DCGS-A SOA Lessons (4) – Grounded in Reality • SOA transformation needs to be carried out under client’s existing programmatic, architectural, and technological contexts and constraints • DoD 5000 / JCIDS acquisition processes • Joint / Army Doctrine (UJTL, AUTL, …) • Industry best practices (CMM, CMMI, Six Sigma, …) • Federal and DoD policies (DoDAF, DISR, NCOW-RM, C2IEDM, …) • Architectural compliance (IEEE 1471, RUP) • Communities of Interest (COI) and cross-organizational working groups • Technology and solution mandates (DIB, …) • Clearly promulgate the information sources that supported the SOA effort 19 MAY 2006
