Product models are representations of a product that help businesses understand its features, benefits, and market potential. They can take various forms, such as physical prototypes, digital simulations, or conceptual frameworks. These models assist in visualizing how a product will function and appeal to customers, guiding development and marketing strategies. In addition to aiding design, product models are essential for testing and validation. They allow companies to gather feedback from potential users and make necessary adjustments before launching the final version. This process can save time and resources, ensuring that the product meets customer needs and expectations effectively.
