Why is iterative testing important in product realization?

Iterative testing is vital in product realization primarily because it offers insights into user preferences. This process involves continuously testing and refining a product based on feedback from real users, enabling designers and engineers to identify what aspects of the product resonate with users and which elements may need improvement. As a result, the iterative approach leads to a more user-centered design, ensuring that the final product better meets customer needs and expectations. Engaging with users early and often throughout the development cycle helps to verify assumptions, reduces risks of product failure, and enhances overall user satisfaction.

While other factors such as reducing time to market can be influenced by the iterative process, the primary strength lies in its ability to focus on user feedback, leading to more successful product outcomes.
