Be REALLY Happy with Your SOA Efforts Thanks to These Resources


More than three-quarters of businesses that have implemented or are working on service-oriented architecture said they are happy with the results in a recent Forrester Research survey. However, only 31 percent of the same group said they had realized all the benefits they expected from SOA.


Apparently some folks are easy to please.


Or, as our Loraine Lawson notes in her great ongoing coverage of SOA and integration issues, it may well be that shops have simply lost sight of the strategic virtues of SOA across the enterprise and now look at it more as a single-use project that they can be "happy" with, at least on a tactical level.


Of course, that's not what SOA is supposed to be about. It's an architecture that promises re-use of services across virtually any business process, either inside or outside your enterprise.


Here in the IT Downloads library, we have numerous resources to help you evaluate the SOA fit for your organization and to guide you in both the tactical and strategic implementation of SOA in your shop. All of these resources are available for free download to IT Business Edge members.


'SOA Governance' Excerpt: This 30-page book excerpt from our partners at InformIT focuses on the often-overlooked differences between governance, methodology and management, with little pearls of wisdom such as:


  • Governance does not dictate when or how to make a decision. It determines who should make the decision and establishes limits for that person or group.
  • Management makes decisions according to governance rules.
  • Neither management nor methodology can replace governance, nor compensate for poor governance.


These issues are fundamental to SOA reaching its full potential, since as an architecture it spans development teams and business units. It has to be based on a strong culture of governance, or it will fragment and become nothing more than a methodology.


The book chapter also includes numerous chart and diagrams, like this scale chart that rates the Autonomy and Control of various governance cultures.
