Defined,SOA Governance is a management capability responsible for overall adoption of Service Oriented Architecture.This function ensures a strategy is established and executed in order to realize measurable benefit,At a high-level this capability is meant to:Manage the journey:setting a strategy,managing progress and ensuring value is realizedEvolve the enterprise capabilities to adopt,build and support an SOAMigrate the organization from being application-centric to service-centricEstablish and manage business&technology alignment,5,Copyright 2006 Accenture All Rights Reserved.,SOA Governance Capabilities,SOA Governance is a new discipline and is crucial to defining and executing an SOA Strategy.This function should contain both Business and Technology leadership to ensure alignment and value realization,SOA Strategy&Roadmap,Service Life Cycle Management,Capability Development,Journey Management&Communication,Develop SOA fit assessment against business strategy&prioritiesAlign business and technology imperativesCreate business case and ROI modelAssess and align roadmap to Corporate project portfolioDefine the organizational approach and structure to successfully adopt SOA,Define the overall service life cycle service definition through service operationsCreate service identification framework for identifying services and ensuring proper level of granularity.Manage services through each phase of the life cycleOversee change management,service dependencies and versioningAssess enabling infrastructure requirements(i.e.repository,dashboard),Manage Business stakeholder expectationsTrack Metrics and budget to measure progress and ensure value is achievedCommunicate progress and status to

support SOA,6,Copyright 2006 Accenture All Rights Reserved.,Industry Perspective on SOA Governance,“Through 2008,70 percent of IT organizations will fail to successfully select and implement an SOA strategy on the first try.These organizations must be prepared to use software services tactically while planning for strategic evolution of their architectures.”-Daryl C.Plummer-Six Missteps That Can Result in SOA Strategy Failure-Gartner,Inc.,June 2005,“SOA is an inherently distributed approach to architecture,and therefore the requirements for governance are even more critical than in more centralized environments.“-David Sprott-The SOA Governance Framework-CDBI,September 2004,“Without an effective governance approach,organizations could quickly face a rather messy and dysfunctional situation with uncontrolled,ad-hoc development of services,undermining the potential benefits of SOA.”-Marianne Hedin-The Impact of SOA on the Consulting Services Market:Some High-Level Observations-IDC,Dec 2005,SOA Governance is recognized as a vital aspect of SOA across the industry,“In 2006,lack of working governance mechanisms in midsize-to-large(greater than 50 services)post-pilot SOA projects will be the most common reason for project failure.”-Paolo Malinverno-The Strategic Impact of SOA Broadens-Gartner,Inc.,November 2005,7,Copyright 2006 Accenture All Rights Reserved.,Potential Risks with Ungoverned SOA,While there are various approaches to managing SOA adoption,there are some serious risks to consider if an active SOA governance approach is not enlisted,8,Copyright 2006 Accenture All Rights Reserved.,Contents,Defining SOA GovernanceRoadmapOrganization Roles&ApproachesService Life Cycle Management,9,Copyright 2006 Accenture All Rights Reserved.,Strategy&Roadmap,Identify Drivers(Business Value),Assess EnterpriseReadiness(Arch/Org),Define SOA Strategy&Roadmap,Identifying the business drivers and assessing the organizational readiness will help determine the appropriate strategy and ultimately the most effective roadmap,Strategy Articulates the business objectives and capability development needs for adopting SOA and the resultant value to be achieved.Roadmap Defines how the strategy should be executed over time to be successful.,10,Copyright 2006 Accenture All Rights Reserved.,High Level Approaches,Services Focus-Focused on establishing a comprehensive services foundationIterative Processes/Services Focus-Focused on automating individual processes while building a foundation of standards-based reusable servicesProcesses Focus-Focused on automating select business processes without planning for a foundation of reusable services,Considering their adoption drivers,organizations are focusing on building a services foundation or increasing their level of process automation,Degree of process automation,Scope of Services,High businessvalue,low businessvalue,100%Automated,0%Automated,Large/CrossEnterprise,Processes Focus,Services Focus,Iterative Process/Service,Semi Automated,Small/Dept,Realized BusinessValue,Medium/BU,While a Process focus may achieve benefits in the very short term,a joint services/process approach must be adopted in order to achieve long term success!,11,Copyright 2006 Accenture All Rights Reserved.,Iterative Processes/Services Focus,In this path the initial focus will be on implementing one or more core business processes with high return on investment.A simple services layer will be put in place for the needs of the business process to be modeled.Iterations will enhance both the services and processes foundation,Early focus will be on a core process.SOA is driven by one or many core business processes with high ROI(example order to cash)Simple processes may be chosen first so that underlying services layer will also remain simpleEvolution of the services layer will be“de concert”with the evolution of the processes layer.As processes become more complex,external and/or require more reliability,the service layer will likewise evolveLessons learned on each increment of the business processes and services enablement will be used to improve the next iteration,12,Copyright 2006 Accenture All Rights Reserved.,The SOA Capability Maturity Model,The maturity model can be used to benchmark an organizations SOA capability and progress towards industrialization,A roadmap will help develop the SOA capability across your organization.The maturity model can be used for planning roadmap activities.,13,Copyright 2006 Accenture All Rights
