Governance requires collaboration. In order for projects to be considered a success, governance is an absolute must - this is particularly true of SOA projects. In this article we combined a number of common mistakes and remarks from a range of IT architects to illustrate and highlight common and critical governance issues. This article presents these issues in a mock interview with a fictional IT architect. All the examples in the interview are based on real-world experiences. I work for a midsize local government. We have about 15,000 employees in 12 departments. I am the lead architect, responsible for architecture and governance. Driven by a real need for agility in our business processes, we embarked on a journey toward a service-oriented architecture about five years ago. One of the first things we did was create a company architecture (often referred to as a reference architecture) which would define the overall architecture for the next few years. The component architecture described all the different (generic) components we expected to need in the next few ...

Some government agencies have considered Service Oriented Architecture (SOA) as the most effective means to address this dire issue. Moving to SOA, however, entails substantial challenges...

Jian Jeff Zhong

In part I of the article, I have described the first four steps of an eight-step SOA development methodology with a focus on architecture, design and abstract thought process. In part II, I will continue to discuss the last four steps concentrating on Web service development, deployment, tests and management. I will then benchmark the case study against industry SOA principles, summarize lessons learned from this real world project and finally share with readers about my considerations for future SOA engagement and practices. After reading both parts, readers should have a complete understanding about SOA strategies, tactics and concrete implementations...
