There have been countless articles written upon SOA failure rates. But how do you define SOA failure? Sure, it's easy when the project is scrapped. But what about the cases in which the SOA project is completed but way overbudget? Success or failure? Most organizations simply aren't mature enough to define the success or failure of a project. Rather, they use the famous Supreme Court "I know it when I see it" measure. I recommend to our customers that quantitative metrics be used to determine success and failure. It's almost always met with resistance, but defining these success/failure metrics helps bring far-fetched expectations into realtiy and results in a better planned project.
