-concepting (by Demo team, tech support from R&D) 
-planning in Jira (by Demo team)
-UI design & QML (by Demo team, R&D UI design & graphics)
-implementation & optimization & integration to end device (by R&D)
-code reviews (organized by R&D, participants Demo team, QtDS team and other relevant R&D teams)

-test automation (R&D, RTA)
-releasing (by R&D)

Benefits
