What is the main goal of user testing in product realization?

The primary focus of user testing in product realization is to gather feedback on usability and performance to improve product design. This process involves engaging real users to interact with a prototype or the final product, allowing designers and engineers to observe how effectively the product meets users' needs and expectations.

User testing provides valuable insights into user experiences, highlighting areas of strength and opportunities for improvement. This feedback loop is crucial for iterating and refining the product, ensuring it is user-friendly, functional, and meets market demands. The goal is to align the product with user requirements and preferences, ultimately enhancing customer satisfaction and increasing the chances of market success.

The other options relate to different aspects of product development but do not capture the primary aim of user testing. Regulatory standards focus on compliance, comparing costs looks at competitive advantage, and finalizing marketing strategies pertains to promotion rather than design refinement. Thus, the essence of user testing lies in its role in shaping the product through direct consumer interaction and feedback.
