What is design validation primarily concerned with?

Design validation primarily focuses on ensuring that a product meets the needs and expectations of the end-user. This aspect is crucial because a product may technically meet specifications or comply with regulations, yet still fail to resonate with or satisfy the users it is intended for. Validation involves gathering feedback from users and stakeholders, and may include various testing methodologies to confirm that the design effectively addresses user requirements and solves the problems it is meant to address.

In this context, while checking adherence to specifications, compliance with regulations, and evaluating production efficiency are all important elements in the product development process, they do not encompass the primary intent of design validation, which is ultimately to ensure that user needs are met. This approach not only leads to successful products but also supports user satisfaction and loyalty.
