Is the first step in the design process. Includes the problem being identified, validated, and justified. The design requirements are determined and the design brief is created.

• prototype

• Valid

• define the problem

• present solution

• construct/test prototype

The engineering design process is iterative. This allows engineers to…

• become proficient at different engineering software applications

• find the most optimal solution to a design problem

• Incorporate both math and science concepts into a design problem

Which step is typically included in a systematic design process?

• Focusing only on the aesthetic aspects of a solution.

• Choosing the first idea that comes to mind.

• Evaluating and refining possible solutions.

• Ignoring all constraints and criteria.

Step 3 in the Engineering Design Process is....
