Open Group releases SOA adoption and governance standards


By David Worthington
August 24, 2009 — 
The Open Group has introduced a vendor-neutral maturity model for service-oriented architecture, as well as a framework to help organizations understand and deploy SOA governance.

The Open Group is an industry consortium dedicated to the free flow of information across systems. It founded its SOA working group in 2005, and the working group's steering committee has four members, two of which work for IBM.

The Open Group Service Integration Maturity Model (OSIMM), released today, provides an extensible method to measure service adoption and integration and to create road maps for incremental transformation to SOA to meet business objectives, according to The Open Group.

OSIMM has seven levels of SOA majority, ranging from "not service-based" to SOA with dynamic service composition, explained Chris Harding, forum director for SOA and semantic interoperability at The Open Group. He works full time for the Open Group, and was previously an independent consultant. An enterprise can develop its own maturity indicators, such as what kind of documents, methods, services and tools must be employed, he added.

"[OSIMM] is a way of assessing where you are, where you want to go, how you are going to get there, and how long it will take," Harding said. It is similar to models that software consultants use to establish what a client needs and what they can deliver to fulfill that need, he said.

However, OSIMM allows enterprises to make that assessment without becoming tied to a vendor solution, Harding said. It can also help developers that have been experimenting with SOA justify a greater use of SOA. "There are weighted indicators, assessment questions, and practices and experience behind it," he said.

Jason Bloomberg, managing partner at analysis firm ZapThink, added, "The Open Group Service Integration Maturity Model was in large part contributed by IBM and includes some IBM-centric content, but The Open Group has done a good job evolving it to be a useful, vendor-neutral tool for helping organizations measure their architectural maturity."

Many SOA maturity models come from software vendors and are little more than software sales tools, said Bloomberg. "ZapThink has found the ones from consulting organizations to be better aligned with enterprise needs."

SOA governance is another "wooly subject" for enterprises, Harding said. "There is not a lot of consensus about what it means, and there is a fuzzy line between governance and management."

The Open Group believes that SOA governance is about how an organization's processes work, and that the value of governance is that it helps an organization build the right services and solutions to enable service reuse, he explained. It also helps organizations deploy and manage services effectively, and to "maintain alignment with business needs," Harding said.

The Open Group SOA Governance Framework defines a set of processes for developing, deploying and operating services. The framework also identifies SOA-specific processes, and it describes how they fit into governance as a whole, he said.

It offers a reference model with starting points, checkpoints and procedures to "make sure things are done right," Harding explained. He said that organizations could take some procedures out as they gain experience.

The Open Group's work is not limited to SOA adoption and governance. It is producing guides for using SOA, legacy evolution to SOA, and SOA security, Harding said.
