After his last great post about the difference between CI and Build Automation tools, Roy Osherove posted the next part about this.  Now he gives us 18 questions to ask when choosing CI and Automated Build tools.  It's a nice list of questions, so read this article http://weblogs.asp.net/rosherove/archive/2010/01/21/18-questions-to-ask-yourself-when-choosing-continuous-integration-and-build-automation-tools.aspx and the next time consider using this list when you have to make a choice.
