Excerpt from Securing SAP S/4HANA.
SAP Fiori is a new user experience (UX) for SAP software and applications. It provides a set of applications that are used in regular business functions such as work approvals, financial apps, calculation apps, and various self-service apps.
The SAP user interface, or SAP GUI as we know it today, was first introduced in 1992 together with the official release of SAP R/3. SAP R/3, the client server edition, was the successor to the SAP R/2 release, the mainframe edition. Although SAP has made several attempts to modernize SAP GUI, an end user from the time it was introduced would still find their way around today. Many transactions and screens have remained the same or changed very little. Since the initial release of SAP GUI, SAP has released several alternative user interfaces such as the SAP Workplace (which was part of the mySAP.com offering), the SAP Enterprise Portal, and the NetWeaver Business Client or NWBC. None were as successful as SAP GUI except, perhaps, for the NetWeaver Business Client. The NetWeaver Business Client is, however, an extension to the SAP GUI. The conclusion of all this is that although many people complained about the old-fashioned look of SAP GUI, they kept using it and will probably continue to do so in the future.
But there is no denying the fact that the user community is changing fast. The SAP users of tomorrow are the youngsters of today, who are used to accessing data from their mobile devices. To them, SAP GUI is a relic from the dark ages. This shift is not limited to youngsters—many end users want data access from any device, from any place, at any time. SAP released SAP Fiori to respond to this demand. SAP Fiori is built using modern design principles you might expect from applications designed for smartphones and tablets. There are already more than 500 role-based Fiori applications such as for HR, Finance, and Business Intelligence. An SAP Fiori application is always limited to a specific task or activity. The design is responsive and deployable on multiple platforms.
There are three types of SAP Fiori applications: transactional apps, fact sheets, and analytical apps.
