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 2005SOAGovernanceisrecognizedasavitalaspectofSOAacrosstheindustry“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.” -

Special attention will be put on planning and assessing of the organization to prepare for an SOA transformation and foundation enablement.This phase, which can be iterative, will see the emergence of the first projects based on SOA principles.Start to make applications available as Web Services.Services start to be composed together to complete a task or create business processes.Emphasis on strategic and business services.Focus on the consolidation of the process and services architecture in creating an enterprise services bus.Design and development are services oriented and process oriented leveraging a set of SOA tools.Services are part of the fabric of business operations.Cross enterprise processes.Federation.Virtual enterprise becomes a reality.Utility and services
