I participated in the free OpenSAP course "Build Your Own SAP Fiori App in the Cloud – 2016 Edition".
You can check some statistics from the last course Build Your Own SAP Fiori App in the Cloud – 2016 Edition
For my Design and Build Challenge I chose to use some functionality from transaction SU01 and create Fiori app from it for unlocking users and resetting passwords.
Here is my story... 
Story
My target is people working on Service desk that need to unlock and/or set new initial password for SAP users outside working hours.
Service support team can perform unlocking of SAP users directly from their smartphone without need to connect via laptops to perform task.
Persona
User Experience Journey
POV (Point of View)
Emily the Service desk specialist needs a way to quickly unlock user and set new initial password so their users can continue to work in SAP without spending too much time while waiting this task to complete.
