SOA and the Zachman Framework
As companies increasingly dive into the complexities of Service-Oriented Architecture (SOA), they need to consider an expanding set of criteria for what must go into the architectures they design. As IT architecture broadly speaking is still relatively immature as a practice, SOA is only now coming into its own as a discipline. Companies are looking for a model to understand the scope of their SOA initiatives so that they can build robust architectures that can withstand the ever-changing landscape of technologies, organizations, and methodologies. One increasingly popular approach for an organization to wrap their arms around the complexity that architecture represents is to use one of the most popular models for understanding Enterprise Architecture (EA) and its role in the business: The Zachman Framework, created by John A. Zachman. Zachman’s key insight was to consider the problem of EA in two dimensions. The first dimension is the various…

Grappling with SOA Change and Version Management
ZapThink frequently speaks of change, since change is the one consistent reality underlying the entire business world. Change, after all, focuses businesses on realizing the benefits of Service-Oriented Architecture (SOA), because the primary reason for embarking on a SOA project is to improve business agility while reducing IT costs in the face of today’s brittle, inflexible, and tightly coupled systems. However, let’s not let the perfume of the SOA rose intoxicate us too much, since implementing SOA itself introduces change every bit as significant as the forces of change that SOA is meant to address. SOA implementations must be built to change, or companies will never be able to realize the agility and cost savings benefits that SOA promises. In particular, a number of change and versioning issues arise when dealing with the sort of living SOA that companies so desire today. Versioning Service Contract Metadata The core…

Solving the Service Granularity Challenge
For us analysts that have been covering the markets around XML, Web Services, and Service Orientation it certainly is heartening to see that our audience of end users, vendors, and consulting firms are now asking some of the more complex and deeper questions around how to do architecture right. It seems that we’ve finally crossed the chasm and architects in particular now have a pretty good idea what SOA is and why they need it. Rather than trying to redefine what SOA is and what is means to the business, people are focusing on the more important issue of how to do SOA right. In that vein, some of our most recent conversations have centered on how to go about building the “right” Services. A key part of answering this question is making sure that we build Services at the right level of granularity. Granularity is a relative measure…

Service Orient or Be Doomed: ZapThink Analysts Announce Publication of their Latest Book!
Ever wonder why businesses are unable to keep up with today’s pace of change? Name your business goal–productivity, profitability, efficiency; today, they all depend on Information Technology (IT). IT is more important to business today than it ever was. While IT in the past has helped companies increasingly make their businesses more productive and efficient, today’s IT is simply getting in the way of change. It is increasingly becoming clear that the way that businesses utilize IT is increasingly making them less agile, less responsive to change, and less able to capitalize on new opportunities. Something has to be done to stop the problem of IT becoming the bottleneck of business. SERVICE ORIENT OR BE DOOMED! How Service Orientation will Change Your Business (Wiley, February 24, 2006;$39.95 cloth) is the first book aimed at regular businesspeople that helps business become more agile by offering technological, process, and cultural changes…
