It is a rare case when only a single design is thought of and used in the creation of a product. Engineers will generally create anywhere from a few, to many different designs so that they can have multiple choices. Certain priorities can be set and then compared to the alternate designs in order to narrow down the list to a couple of designs that seem most appropriate, and most viable to move forward with. Without this process, there would be too much time and resource waste that would leave the project high and dry. There's also the chance that the end result may end poorly because it doesn't fit the requirements that were specified by the customer. Engineers must take the time to think through their solutions and make sure they are the best at what they are going to solve.
