What does user-centred design primarily ensure?

User-centred design fundamentally emphasizes the importance of understanding and prioritizing the primary needs of users throughout the entire design process. This approach involves deep engagement with users to gather insights about their preferences, behaviors, and challenges. By placing users at the center of the design, the resulting products are more likely to be functional, useful, and ultimately satisfying to the target audience.

This methodology contributes to creating solutions that are tailored to meet the actual demands of users rather than relying solely on assumptions about what they may want. As a result, products developed through user-centred design are typically more effective in solving the problems they aim to address, leading to greater user satisfaction and engagement.

Other options, while important in product development, focus on different aspects. Product cost-effectiveness and retail viability pertain to the economic aspects of product development, and advanced technological integration deals more with the technical sophistication of the product rather than the user's actual needs.
