Which type of prototype is focused on exploring customer-facing views?

The correct choice focuses on horizontal prototypes, which are primarily aimed at showcasing the user interface and customer-facing components of a system. These prototypes provide a broad view of how different screens and functionalities interact without diving deep into the underlying details of the system's architecture or workflows.

Horizontal prototypes are particularly useful in the early stages of development as they allow stakeholders to visualize the overall user experience, explore different design options, and gather feedback on the layout and usability of the user interface. This type of prototype helps in understanding what the end-user will see and how they will interact with the system, making it invaluable for ensuring that the project aligns with customer expectations.

In contrast, other types of prototypes may focus on different aspects. For example, vertical prototypes delve into specific features or functions, showcasing in-depth implementation of particular areas but not necessarily the customer-facing views as a whole. Static prototypes convey fixed designs without interactivity, which can limit feedback on user experience. Dynamic prototypes, while they can simulate user interactions, may not specifically emphasize the customer-facing views as effectively as a horizontal prototype.
