What are the key components of the architecture American Express has created?
The key components of the architecture American Express had created were the ability to provide a common language for leaders to use to collaborate and transform business by utilizing the new payment methods using mobile devices.
American Express uses the enterprise architecture as the blueprint or guideline for the organization to follow. It streamlined the processes and leveraged the IT resources to keep up with the change in new payment methods.
The textbook didn’t specifically talk about the mobile app, but I think it refers to the Amex Mobile App for the mobile payment.
