Imagine
Why do scientists follow the engineering design process?
To find solutions to problems.
What might happen after a product is tested but before it is produced in large numbers?
The product will be redesigned to make a better product
What do engineers do if a design doesn’t work well after testing?
Redesign or improve it.
The project must be completed today. Criteria or constraint.
What is the 3rd step?
Plan
What is the first step in the engineering design process?
Identify a need or problem to be solved
