Explain why enterprise architecture is important for organizations

What will be an ideal response?

The enterprise architecture (EA) is the big picture for organizations, the blueprint that describes the current environment and the target environment organizations hope to reach to achieve their missions. It also includes a roadmap for moving from the baseline to the target, to help managers make better decisions that focus on long-term benefits and not just short-term gains. The architecture is not just about hardware, software, and telecommunications assets, though that is a key component. It encompasses the people, technology, processes, and data that make up information systems, and it should be driven by business requirements and the organization's mission.
The enterprise architecture can be illustrated as layers, in which the business mission at the top drives decisions about data and applications architectures. These should then shape the ICT architecture, to include hardware, software, and communications.
