What is the primary function of testing during design development?

The primary function of testing during design development is to verify product specifications and user needs. This process ensures that the product meets the designated requirements and functions as intended. By testing, designers can assess how well the product aligns with the expectations and needs of its users, gathering critical feedback that informs further design iterations.

This validation process often involves evaluating usability, functionality, safety, and overall performance, which helps identify any issues early in the development cycle. Addressing these concerns before mass production not only enhances the product's quality but also increases the likelihood of user satisfaction upon release.

While enhancing aesthetic appeal, reducing production costs, and conducting market research are important considerations in the overall design and business process, they are secondary to the primary goal of ensuring that the product effectively meets user needs and specifications through rigorous testing.
