On your computer, you draft a design for a valve for an improved artificial heart, running simulations of how well different materials would work. You then work with a model maker at your medical device company, who will create a prototype of your design. Meanwhile, a fellow engineer is devising a machine to test your prototype. Once the prototype has been tested, you'll meet with your boss and three other engineers—each of whom developed a different prototype valve. You'll discuss the advantages and disadvantages of each, so you can settle on one that incorporates the best features of all three.
