PRODUCT DESIGN PERSPECTIVE
Sora Kimura
Human Factors & Risk
The question this perspective asks
Are permission, uncertainty, and risk clear before a person acts?
This perspective checks what the interface communicates at the moment of decision. Users should see what is known, what is uncertain, which account is affected, and whether an action can be undone.
What it checks
Plain choicesControls describe consequences, not internal jargon.
Risk before actionAccount, size, cost, and risk appear before approval.
Clear statusA proposal is never mistaken for a completed trade.
