Game Dev Tycoon Design and Technology?

Hello! I was just wondering which stuff is Design and which is Technology?

Engine=?
Gameplay=?
Story/Quests=?
Dialogues=?
Level Design=?
AI=?
World Design=?
Graphics=?
Sound=?

Have a look at the first table in this link as they are all kind of both http://gamedevtycoon.wikia.com/wiki/Game_Development#Development_phase

the predominant types for each are as follows

Engine=Tech
Gameplay=Design
Story/Quests=Design
Dialogues=Design
Level Design=Tech (Design also, but mostly Tech)
AI=Tech
World Design=Design (Also Tech but more Design involved)
Graphics=Both
Sound=Both (slightly more Design however)

Okay. Thank you very much!
