Fiori Elements can save development time and provide a consistent user experience across SAP Fiori apps, if you know a bit about what's under the hood.
The approach has advantages and restrictions compared to developing completely custom front-end applications that developers and managers should be aware of. Its main advantages are that it reduces the cost and time required for application development and maintenance, and helps provide a consistent and robust user experience to business users.
Smart controls cover a variety of use cases, including forms, charts, and tables (see the figure below for an example), while Fiori Elements are available that provide reports with lists and filters, object pages for detailed information about a specific object, and overview pages for dashboard-style information about a particular subject.
To provide the advantage of mostly ready-made applications, Fiori Elements and smart controls limit the amount of customization that can be easily achieved.
