A "product model" is a representation of a product that outlines its features, specifications, and functionalities. It serves as a blueprint for understanding how the product works and what it offers to consumers. This model can be physical, like a prototype, or digital, such as a 3D rendering or a software simulation. In business, product models help teams visualize and communicate ideas during the development process. They can also assist in market analysis by identifying target audiences and potential improvements. Overall, product models are essential tools for effective product design and marketing strategies.
