Final answer:
A prototype is a working model created to test and improve design decisions, commonly used in architecture and product design, prior to the final development of a new system or product.
Step-by-step explanation:
The process you are referring to is known as building a prototype. A prototype is a trial working model of a design that serves to test design decisions and identify potential problems within a new system or product before it is fully developed and brought to the market. This concept is quite common in various fields, including architecture and product design. As in your example, an architect may construct a physical model of an office building to visualize and explore the impact of the building on a city block. Similarly, companies may create rough models of their new products to demonstrate functionality and test practicality. These models are not as polished as the final products but are essential for iterative development and refinement.
