Design Project

What will a good acrylic design project include?
I need to know what a good acrylic design project will include. Such as originality.
It should be Original as you say but also it should be:
suitable for its intended use,
easy to use
good looking
Colour is given thought re its intended location / use
robust, ie will last / is strong enough etc
It’s suitable for mass production (if that’s part of the plan)
The production cost is acceptable
It is something that will be sale able
Hope this helps.
