- Define the Problem. The engineering design process starts when you ask the following questions about problems that you observe: What is the problem or need?
- Do Background Research. Learn from the experiences of others — this can help you find out about existing solutions to similar problems, and avoid mistakes that were made in the past.
- Specify Requirements. Design requirements state the important characteristics that your solution must meet to succeed. One of the best ways to identify the design requirements for your solution is to analyze the concrete example of a similar, existing product, noting each of its key features.
- Brainstorm Solutions. There are always many good possibilities for solving design problems. If you focus on just one before looking at the alternatives, it is almost certain that you are overlooking a better solution.

What is the problem that needs to be solved? Who is the design product for, and why is it important to find a solution? What are the limitations and requirements? Engineers need to ask these types of critical questions regardless of what is being created.
Good designers brainstorm possible solutions before opting to start a design, building a list of as many solutions as possible. It is best to avoid judging the designs and instead just let the ideas flow.
Use the experience of others to explore possibilities. By researching past projects you can avoid the problems faced by others. You should speak to people from various backgrounds, including users or customers. You may find some solutions that you had not considered.
Having listed potential solutions and determined the needs of the project alongside your research, the next step is to establish any factors that may constrain your work. This can be done by revisiting the requirements and bringing together your findings and ideas from previous steps.
You may wish to consider further solutions to compare the potential outcomes and find the best approach. This will involve repeating some of the earlier steps for each viable idea.
Once you have assessed your various options you can determine which approach best meets your requirements. Reject those that don’t meet your requirements.
Having chosen your approach, the next step is to refine and improve the solution to create a design proposal. This stage can be ongoing through the length of your project and even after a product has been delivered to customers.
Use your design proposal to make a prototype that will allow you to test how the final product will perform. Prototypes are often made from different materials than the final version and are generally finished to a lesser standard.
Each prototype will need testing, re-evaluation and improvement. Testing and evaluation allows you to see where any improvements are needed.
Once testing has been completed, the design can be revised and improved. This step can be repeated several times as more prototypes are created and evaluated.
One example framing of the engineering design process delineates the following stages: research, conceptualization, feasibility assessment, establishing design requirements, preliminary design, detailed design, production planning and tool design, and production. [2]

The engineering design process is a series of steps that guides engineering teams as we solve problems. The design process is iterative, meaning that we repeat the steps as many times as needed, making improvements along the way as we learn from failure and uncover new design possibilities to arrive at great solutions.
The engineering design process is a series of steps that engineers use to create solutions to problems. It is a structured approach to problem-solving that involves identifying a problem, defining the problem, generating potential solutions, evaluating those solutions, selecting the best solution, and implementing and testing that solution.
What Is the Engineering Design Process? Learn what it takes to get from concept to prototype.
Engineering is the creative process of turning abstract ideas into physical representations (products or systems). What distinguishes engineers from painters, poets, or sculptors is that engineers apply their creative energies to producing products or systems that meet human needs. This creative act is called design.
