Question #N1287
The process of creating a new product involves a series of steps, each of which is critical to the success of the final product. The first step is to identify a need in the market, that is, to determine what consumers want or need. Once a need is identified, the next step is to come up with a solution that meets that need. After a solution is developed, it must be tested to ensure that it works as intended. Finally, the product must be manufactured and marketed.
