.. it is not poor governance that causes SOA failures but rather governance itself is a single point of failure and a pessimistic organizational structure that causes SOA to fail.
It reminded me about a presentation I attended at the LAC 2009 conference, by Frank Schalkwijk (Atos Origin), on Emerging Architectures. He argues that it's better to 'engage' our specialists than to 'govern' them. That way an architecture can 'emerge' with a lot more support in your organization. Hmmm.
