Which statement is true regarding the functionality of the SAP Fiori launchpad?

The functionality of the SAP Fiori launchpad is designed to enhance user experience by providing a customizable interface. Users can indeed personalize their launchpad layouts according to their individual preferences, which includes rearranging tiles, adding or removing applications, or modifying what is displayed to better fit their needs. This flexibility helps to improve efficiency and user satisfaction, making it easier for users to access the applications and information they require.

The other options do not align with the key capabilities of the SAP Fiori launchpad. The prohibition of user modifications, limited access to system administrators, and independence from user roles do not reflect the core functionalities and principles of user-driven customization that the launchpad embodies. It directly supports user choice and personalization, which is a significant aspect of its design.
