Joe McKendrick writes that SOA governance must improve in ZDNet. Interestingly, McKendrick states that some do not like the word governance itself.  But SOA really does need governance, especially when it comes to versioning, SLA, etc.  Without governance, your SOA can quickly become an unnavigable mess.   KPI has experience with a number of SOA governance tools, including AmberPoint, WSRR, Actional, and Systinet.   None complete the total solution, but AmberPoint seems to be the most dedicated to governance.
