Which user interface in SAP S/4HANA offers a role-based experience across various devices?

The user interface that offers a role-based experience across various devices in SAP S/4HANA is SAP Fiori. SAP Fiori is designed with a modern, intuitive approach that focuses on enhancing user experience by providing a consistent interface tailored to the specific needs of users based on their roles. This allows for a more efficient workflow and greater engagement as users interact with applications that are relevant to them.

SAP Fiori employs responsive design principles, ensuring that applications can be accessed seamlessly across different devices, including desktops, tablets, and smartphones. This flexibility promotes productivity and allows users to work from anywhere, fitting modern work ecosystem demands.

In contrast, other choices do not offer the same level of role-based personalization and cross-device compatibility. SAP Easy Access is more traditional and does not have the same user-friendly, responsive attributes. SAP GUI is another legacy interface primarily designed for desktop use, lacking the modern usability features of Fiori. SAP Screen Personas focuses on customizing existing SAP GUI screens, providing better usability but still relies on the underlying SAP GUI framework, meaning it lacks the broader role-based adaptation and mobile-compatibility of SAP Fiori.
