So far, there are precious few case studies on SOA. The SOA Consortium, which formed in February, is helping fill that gap with its SOA Industry Case Study Forum.
Soon, the consortium hopes to have a major new case study to add as the U.S. Army implements SOA.
This would be a major case study in part because of the challenges moving the Army to a loosely-coupled architecture. According to ADT Magazine, the Army runs multiple solutions on different platforms and, obviously, in various locations. The Army is determining whether SOA could offer a more cost-effective way to manage this diverse infrastructure.
The Consortium, which met recently, also announced the formation of a new strategy group designed to educate IT professionals on ways to connect various business processes, such as Business Process Management, Six Sigma, and Lean, with SOA.
The Case Study forum launched without fanfare late last month, so you may have missed it. (I did!) It's a nice resource, though, offering case studies organized by industry, as well as by whether the projects were business- or IT-lead, mega projects or proof of concept projects.
The SOA Consortium is a coalition of SOA advocates, including end users, service providers, and vendors.
