Which principle is not part of the SAP Fiori design principles?

The principle that is not part of the SAP Fiori design principles is rooted in the understanding of what Fiori aims to achieve in terms of user experience. SAP Fiori focuses on delivering a design that is simple, intuitive, and closely aligned with user roles and tasks.

The principles of simplicity, ease of use, and role-based functionality are central to Fiori. By emphasizing simplicity, Fiori aims to provide an interface that minimizes complexity and enhances clarity for the user. "Easy to use" underlines the expectation that users should be able to interact with the application without extensive training or support. Lastly, being role-based means that the applications are designed to cater to the specific needs of different users based on their roles within an organization, ensuring that relevant information and actions are prioritized.

In contrast, the notion of "functional" does not align with the core focus of Fiori principles, which prioritize user experience and interaction over mere functionality. While functionality is important, Fiori’s design ethos emphasizes creating applications that are not only functional but also meet the essential criteria of being simple, user-friendly, and role-specific. Thus, identifying "functional" as a principle highlights a misalignment with the fundamental values that guide the Fiori design framework.
