More and more, large global enterprises are going for global modes of operation, including global IT and, in particular, globally used applications. Enterprise architecture (EA) is one of the crucial tools organizations should use to establish global IT successfully. Forrester interviewed architects working in global enterprise architecture initiatives to learn about the experiences of EA groups working to support their organization's move toward global IT. These case studies offer actionable advice for EA organizations undergoing the global shift; for example, a short time to delivery is more important for the success of global EA than perfectly tuned global EA governance processes.
