SAP Fiori is SAP’s user experience approach, while SAPUI5 is a framework for building business applications. Work often combines role-based launchpad setup, app extension, OData services and accessibility.
Fiori defines the experience and design approach; UI5 is one technology used to deliver it.
A practical SAP Fiori engagement begins with an inventory of the installed product and release, affected business processes, connected systems and decision-makers. From there, the team can define scope, data and integration requirements, testing responsibilities and a realistic transition or support plan.
