4.1: Enterprise

Implement the Service-Oriented Enterprise

Other Information:

Establishing the service-oriented enterprise is perhaps the most difficult aspect of SOA because it challenges many of the conventional business practices employed today. This section highlights key enterprise changes necessary to enable the benefits from SOA. Recommendations for Service Oriented Enterprise: • Treat SOA as a change initiative. It must have strong executive buy-in, adequate resources, organizational visibility and sustained support. • Create a program plan with goals and objectives, and objective performance measures for the SOA initiative. • Establish a Center of Excellence (COE) to guide and manage the SOA initiative. • Adequately fund the COE and the SOA initiative. • Develop and sustain appropriate and viable Communities of Interest (COI) to help facilitate the development and use of shared standards, platforms and semantics. • Establish formal funding mechanisms to support the creation and delivery of services, coupled with appropriate charging mechanisms that are tied to service usage. • Establish a Federated Governance structure that includes a charter defining organizational structure and relationships, scope of responsibility, rules of behavior, conflict resolution processes and the authority and structure of the COE. • Adopt a twin-track SDLC that facilitates the incremental, innovative refresh of the IT assets on an on-going basis. • Create and use a services development, test and evaluation laboratory to meet enterprise requirements. • Adopt procurement policies and processes that encourage vendor competition around service models.
