4. 4 Klaus-Dieter Platte / Platte.Consult 3G Mobile Context Sensitive Adaptability User Friendly Mobile Work Place for Seamless Enterprise Applications 21/06/2015www.consensus-online.org Problem Statement Today... mConventional (HTML-) Web Browsers are the primary means of access to applications. mApplication UI are optimized for them. mAdaptation to mobile device access costly and cumbersome. mA dissatisfying mobile UI turns people away from using applications via mobile devices. mLow number of users + costly adaptation = no business case.

5. 5 Klaus-Dieter Platte / Platte.Consult 3G Mobile Context Sensitive Adaptability User Friendly Mobile Work Place for Seamless Enterprise Applications 21/06/2015www.consensus-online.org Challenge is...... to bring (potentially) all applications to (potentially) all devices mToday exist already ~50 different mobile devices with different device capabilities – voice comes on top of that m For a single application to be displayed on 50 devices 50 sets of application UI need to be created! mSome enterprises are maintaining hundreds of applications – customer developments & customization comes on top of that m Example: For all SAP applications being able to be displayed on all devices 50.000 sets of application UIs need to be created!
