Which statement is a guiding principle of user-centered design?

• A. The user is consulted only at the final stage.
• B. Users are not involved in development.
• C. The design takes full account of users, their activities and use of the product.
• D. The design is guided primarily by automated heuristics instead of user input.

Answer: (C)

The guiding principle is designing around the people who will use the product—their tasks, contexts, and needs—throughout the whole process. This approach means you continuously learn about users, test ideas with them, and refine the design based on how they actually work with the product in real settings. That is why the statement about taking full account of users, their activities and how they will use the product is the best fit. It captures the essence of user-centered design: decisions are driven by a clear understanding of who the users are, what they need to do, and where or how they’ll interact with the product. It implies involving users, evaluating prototypes with them, and iterating to improve usability and satisfaction. In contrast, consulting users only at the final stage misses early discovery and iterative feedback; excluding users from development contradicts the approach; and relying mainly on automated heuristics focuses on generic rules rather than actual user needs. Heuristics can aid evaluation, but they don’t replace designing around real users.
