What does model validation help identify?

Model validation is a critical process in engineering and product development that ensures the model accurately represents the reality it is intended to simulate. One of the primary purposes of model validation is to determine whether the design or product effectively meets user needs and expectations. This process typically involves comparing the outputs and predictions of the model against real-world scenarios or user feedback to confirm that the desired requirements and functionalities are achieved.

In the context of engineering practice, understanding if user needs are being met is essential because it relates directly to the purpose of the design. A model that does not align with user requirements may lead to products that are ineffective, unsatisfactory, or fail in the market. This validation process allows engineers to refine and adjust their designs based on user feedback and observed performance, ultimately enhancing the quality and success of the final product.
