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

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

Page 15
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

Page 16
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
UNCLASSIFIED
Page 17
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
