Once a part does work, engineers consider its effectiveness, cost, reliability, and safety. Often parts are redesigned many times until they meet the requirements. This program allows engineers to create three-dimensional models of objects on the computer. The objects can be analyzed on the computer which saves time and money. Once a computer is designed and in production, computer engineers with different specialties are involved.
Production engineers supervise the manufacturing process.
For example they supervise the workers and make sure all the needed supplies are at the plant. Quality assurance engineers control the production process. They make sure that the product is made correctly. They also check finished products for flaws. Even before the product is designed, development engineers help create the new product ideas.
