When manufacturers make products, people always look to see how the device could be improved, even if the product released is very successful. One method of improving a device is called reverse engineering. In this process, a designer breaks down a product to see which parts of it could be improved in any way. New parts may be introduced for a better performance, or a part or two may be removed. It is always important to look to see how you can improve a product because as time passes, consumers want different and better things. By obeying the needs of its buyers, a company keeps bringing in money, which allows them to keep improving themselves as a business.
