In product design, what term refers to the essential requirements a product must satisfy in relation to the user?

• A. Design brief
• B. User need
• C. Market requirement
• D. Product specification

Answer: (B)

Focusing on what users require from a product is the central idea. User needs capture the essential requirements from the user’s perspective—the problems to solve, goals to achieve, and the experiences the product should enable. They guide decisions so every feature and decision helps the user complete tasks or gain value. This makes user needs the best fit for describing what the product must satisfy for the user.

The design brief is a project plan that outlines what to deliver and the constraints of the design process. The market requirement describes expectations from the wider market or stakeholders, not just the individual user. The product specification turns those needs into concrete, measurable targets the product must meet, but it’s built from understanding the user needs first.
