An engineer has designed and built a prototype to improve the brake system of a car. What is the next step that the engineer should take in the process?

• Test the prototype.
• Make sketches of the prototype.
• Identify constraints.
• Collect and analyze the test results. 

What is the first step in the Design Process?

• Identify the Problem
• Construct a Prototype
• Develop Possible Solutions
• Optimize

A prototype is a model that

• functions like the final solution would
• is made of the same materials as the final product
• is made after the final product is made
• has to be 3D

The five steps that engineers use to design something to solve a problem, to: Ask, Imagine, Plan, Create, and Improve.
