Economic and compliance value of SOA Governance
Client experience highlights the need for SOA Governance:


 From day one of SOA implementation
  – To realize full savings and value that come with reuse of assets

 To meet compliance requirements
  – IBM’s SOA Governance framework provides both a process and
    the enabling tools for tracking and reporting of service usage
    and security
  – Example: Increased legal requirements in the finance industry
    and public sector mean that governance and enforcement of
    service usage is even more important today



    "SOA governance can assure a greater return on investment for SOA
    projects, especially since the impact of these projects can measured
    in a consistent way across the enterprise."

Success drivers are based on a federated
governance approach
 Key Success Drivers:
  Assess organizational readiness for federation
  – Skills, Communications, Leadership, Teaming
  Integrate federation into current SOA implementation plan
  – Understanding, Acceptance, Preparation, Commitment
                       Governance Approaches
                        Centralized – Single solution/product focused
                        Federated – Growth based on Smart SOA requirements
                        Decentralized – multiple, disparate tools (ie, spreadsheets)
