只有20%的SOA项目是成功的

根据一份调查（http://www.infoq.com/news/2008/07/Only1），在20个SOA项目中，有50%是完全失败，30%不死不活，也就是说只有20%的项目算是成功的。
认为造成失败的因素有：

• Lack of defined service models
• Infrastructure focus
• Governance only of SOAP-based systems, if that
• Failure of developers to leverage the runtime governance in place
• Initiatives led by and solely involving the app dev group
• Roadmaps lacking specificity
• Inability to measure ROI
• Project-centric culture
• An "I'm special" attitude

看来不止在国内SOA被认为忽悠（ http://www.iteye.com/topic/186309 )，在国外也开始有SOA who you的说法了。
