Which layer in the Architecture Canvas is responsible for user interfaces and processes?

The End-User Layer is responsible for user interfaces and processes because it directly interacts with the end users of the application. This layer is focused on the presentation of data, ensuring that all user-facing elements are effectively designed to facilitate user interaction. It includes components such as web pages, mobile applications, and other interfaces that users engage with to perform tasks, access functionalities, and navigate through the application.

By encapsulating all the user-facing elements, the End-User Layer emphasizes usability and user experience, making it a critical part of the architecture when considering how end users will interact with the application. It operates at the surface level of the application architecture, where user interaction begins, providing a seamless experience and ensuring that the intended functionality is delivered effectively to the user.

The other layers, while crucial for different aspects of the application’s architecture, do not specifically focus on user interaction or user interface design. Instead, they support the End-User Layer in other capacities, but this layer is where the actual interface and processes that the end user experiences are designed and executed.
