Optimizing the Enterprise for SOA: From Project Management to Program Management to the "Network Organization" by William Perlowitz To achieve the benefits of SOA, enterprises must realize that traditional approaches to IT project management (where a project is considered in isolation, requirements are defined, and budgets are allocated) can no longer work. This article explores why the shift to treating IT as a continually evolving asset must occur. We describe why a radical change from traditional IT project management to program management and organization must be made and we conclude by introducing the concept of the "Network Organization"...

Ten Strategies for Overcoming the Technological Impact of SOA Governance
by Robert Schneider As many enterprises currently carrying service-oriented initiatives have learned the hard way, SOA governance isn't a “nice-to-have” option. Instead, it's vital to the long-term health and effectiveness of the undertaking. What makes governance particularly challenging is the sheer number of interacting software assets found in a typical service-oriented architecture. Forward-thinking organizations have turned to SOA governance automation to help manage this daunting task. This article offers a series of simple tips and tactics to bolster the likelihood of being successful when selecting and implementing SOA governance technology. It also points out the interplay between governance solutions and the major phases of a service-oriented initiative... [view] |

Defining Business Services in the Telecommunications Industry
by Stuart Kerrigan and Richard van Schelven For many companies in the telecommunications sector, SOA adoption is essential to their growth and survival. This article explores the integration of concepts associated with SOA and service-orientation into a typical telecom enterprise by explaining how key SOA characteristics and principles tie into the typical telecom organizational structure, leading to an opportunity to define business services and establish a Service Solution Set Inventory (SSSI) as the foundation from which services can be repeatedly composed into aggregate applications. Along the way, we will explain some basic terminology related to distinguishing core from context processes and differentiating between the various types of clients and consumers that acquire service-oriented systems...

Business Process Analysis with SOA: A Case Study by Wajid Khattak The success of any IT initiative could be measured in terms of the actual business goals that it fulfills. However, when it comes to SOA based projects, it becomes imperative that such an initiative bears close correspondence with the business requirements as SOA is usually an enterprise-wide activity. In order to achieve this required alignment, it stands necessary that before starting off with the service-oriented analysis phase, a high level view of required SOA needs to be in place that ensures that the subsequent analysis phase concentrates on business processes. Business process analysis offers matrices that help in drawing a correspondence between business goals and high level services... [view] |

Web Service Contract Versioning Fundamentals Part I: Versioning and Compatibility
by Thomas Erl, David Orchard and James Pasley Web services have made it possible to build services with fully decoupled contracts that leverage industry standards to establish a vendor-neutral communications framework. Though powerful and flexible, this framework brings with it an on-going responsibility to effectively manage those service contracts as the services continue to evolve over time. One of the most critical aspects of service governance is contract versioning. This first of two articles comprised of excerpts from the recently released "Web Service Contract Design & Versioning for SOA" book explores fundamental service contract versioning issues, including compatible and incompatible versioning requirements...
