TOGAF defines interoperability as "the ability to share information and services". Which category uses a common look-and-feel to interact with users?

The concept of interoperability within TOGAF emphasizes the importance of sharing information and services across different systems and platforms. When considering the specific category that employs a common look-and-feel to interact with users, presentation interoperability is the most fitting choice. This category focuses on ensuring that the user interface is consistent and user-friendly, allowing users to seamlessly engage with various applications or services without being hindered by differences in design or functionality.

Presentation interoperability serves to provide a coherent user experience, which is critical in environments where multiple systems may interact or exchange data. By ensuring that the look-and-feel is uniform, users can easily navigate through different applications without needing to familiarize themselves with varied interfaces each time a new system is accessed.

In contrast, application interoperability refers to the capability of different software applications to communicate and work together; information interoperability involves the shared understanding and sharing of data between systems; while technical interoperability relates to the underlying protocols and standards that facilitate connectivity and integration between the systems. None of these other categories specifically highlight the importance of a uniform user experience, making presentation interoperability the correct focus in this context.
