Final answer:
The engineering design process involves iterative phases of requirements gathering, design, build, and evaluation/risk analysis. The spiral design process allows for multiple iterations to refine the design and improve the final result.
Step-by-step explanation:
The engineering design process cycles through four phases: requirements gathering, design, build, and evaluation/risk analysis. These phases are iterative, meaning they can be repeated multiple times until the desired result is achieved. For example, during the design phase, the team may prototype, test, and refine the design multiple times based on the results of the evaluation.
Throughout the process, the design may be refined, weaknesses may be identified and addressed, and changes may be made to improve the final design. This iterative nature of the engineering design process is often referred to as the spiral design process, where each iteration builds upon the previous one to create a better end result.
The advantage of using a spiral design process is that it leads to a better final design. However, it is important to note that the spiral design process requires time and resources for each iteration, which should be carefully planned to avoid delays and budget overruns.
