Introduction to Engineering Design Process

The engineering design process is a set of steps that engineers follow to come up with a solution to a particular problem. The solution to the problem involves the designing of a product that can accomplish a certain task and can qualify certain criteria. The process of designing is completely different from that of the scientific method, that you may be familiar with. If the project utilizes the observations, and the experiments then the engineering design process must be followed. The diagram shows the steps of the engineering design process, and the table below describes each step in more detail:
