Define the problem

Decide on the best solution

Have a test pilot attempt to fly it from one location to another.

See if the car can hover one meter above the ground for 20 minutes.

Drive in the car at highway speeds on an interstate roadway at nighttime.

Build a prototype of the new drill

Improve the design of the system

Evaluate the results of the system

Build a prototype of the system

to test the product and make sure that it is the best solution to the problem

to make sure that the product is in compliance with government regulations

to determine the design constraints for the product

analyzing the problems that people have using standard keyboards

asking people their opinions of how they like standard keyboards

comparing the speeds at which people type on each style of keyboard

Place it in someone’s home, and see if it can vacuum the carpets on its own.

They should go ahead and build a prototype of this design.

Place it in a grassy field, and observe to see if it can vacuum up dirt and sand.

After the model is built

after the model is tested

 Before the model is built

The proper cost analysis was not performed.

The designers did not test other types of machines.

They did not rigorously test and modify the prototype
