Back

The Engineering Design Process is used to develop solutions to problems through a series of steps.

Front

What does the 'Plan' step in the Engineering Design Process involve?

Back

The 'Plan' step involves evaluating brainstormed ideas and ruling out those that don't meet criteria and constraints.
