Service-Oriented Architecture Governance for the Services Driven Enterprise

by Eric A. Marks

Overview

If you are leading the charge to adopt service-oriented architecture (SOA) within your enterprise, you know that successful implementation of SOA is challenging to the point that many organizations just avoid confronting the SOA governance issue altogether. Capturing a wealth of practical experience and lessons learned in what has become the hottest topic in business, Service-Oriented Architecture Governance for the Services Driven Enterprise insightfully presents a proven model of Enterprise SOA Governance, augmented by a governance modeling design framework and a body of governance modeling tools and techniques to meet all of your enterprise SOA governance requirements.

Whether you are a technical or business executive, this how-to manual presents the breadth, richness, and scope of its concepts in the context of your entire enterprise and straightforwardly explores the complexities and nuances of IT and SOA governance, clearly presenting:

• Some of the common mistakesa??and their solutionsa??that organizations make as they focus their efforts on governance

• An SOA governance reference model to help break down the concept of governance into bite-sized chunks

• The Four-Tiered Model of Enterprise Governance to isolate your governance challenges, gaps, and requirements

• An inventory of major enterprise governance processes to help you understand and plan your SOA governance requirements

• The SOA governance modeling tools and an assessment framework

• How you can design and implement your own enterprise SOA governance model and policies

• How to establish an enterprise SOA governance framework within the context of corporate governance, IT governance, and enterprise architecture governance

• Various governance organizational design patterns that will enable your governance model to adapt and evolve in concert with your relative SOA maturity

Presenting a governance model assessment and design framework based on years of accumulated experience from the trenches of enterprise SOA governance, Service-Oriented Architecture Governance for the Services Driven Enterprise uniquely distills the complex dynamics of SOA and governance to equip you in implementing SOA governance that reflects your organization's strategic and business focus.
