Which of the following is a purpose of modeling in design?

Modeling in design serves several crucial purposes, and one of the primary reasons is to carry out evaluations and implement changes. By creating models, designers can simulate how a product or system will function in real life, allowing them to observe strengths and weaknesses. This evaluative process is essential for refining designs, improving usability, and ensuring that the final product meets the intended requirements.

Evaluating through models helps identify potential issues early in the design process, which can lead to more effective and informed modifications. These changes can significantly enhance the overall quality and performance of the final design, making this purpose of modeling integral to successful design practice.

While reducing material costs, generating marketing strategies, and developing packaging designs may be associated with various aspects of product development and design, they are not the primary focus of modeling itself. Modeling primarily serves as a tool for evaluation and iteration, which is essential in the design process.
