iPhones have changed the whole meaning of user experience. Virtually all the new mobile phones are smart-phones. Companies are allowing BYOD (Bring Your Own Device). Emails are already an integral part of smart-phones. The next big thing is enabling Business Processes. The technology is very much there but the mind-set is still developing. With the laptop screens, the only design consideration was to put everything on the screen. The user would 'learn' to find what they needed.
But with iPhones, that is no longer the case. The form factor is small, the user attention span is in seconds. SAP functional consultants now have to add user design into their repertoire to really delivery a good solution.
I have started to design screens for SAP HR and SAP Workflow that I will post here for discussion soon.
