Question

why is creating a prototype, or experimental model, a good idea? it takes less time than creating multiple solutions. the engineer will not need to make changes afterward. it allows the engineer to test an idea before creating the final design. it is the fun step of the process.

Explanation:

A prototype is a preliminary model. Its main purpose is to enable engineers to test concepts and functionality before investing in a final - design. It doesn't guarantee no - changes, and time - comparison to multiple solutions isn't its main advantage. While it might be fun for some, that's not the key reason for its creation.

Answer:

It allows the engineer to test an idea before creating the final design.
