What is the Engineering Design Process?
The engineering design process is a series of steps that engineers follow to come up with a solution to a problem. Many times the solution involves designing a product (like a machine or computer code) that meets certain criteria and/or accomplishes a certain task.

1 - Identify the Problem
A bridge needs to be built in 5 days with 25 straws and 2 tubes of hot glue that will span 10ā and be a minimum of 2ā wide. It needs to hold a minimum of 5 lbs and we are working in teams of three.

2 - Identifying Criteria
Identify Criteria and Constraints
What exactly should the device do?
What should it not do?

3- Brainstorm Alternative Ideas
All ideas are ok
This begins the creative part
Any format is ok. (words, sketches)

I wonder what qualities make up a person who is good at brainstorming...
4- Generate Ideas
Narrow down the possibilities
Decide on 2-3 alternatives
Predict the outcome of each alternative

5 - Explore Possibilities
Use a KWL chart
What information must we locate?
Perform the research

6 - Decide on the Final Designļæ½Select Your Approach
Narrow down the possibilities
Decide on the best idea
Justify the idea
Create sketches & formal documents.
Test ideas and materials

Assume you had to design a car that flew, draw out your sketch.
7 - Build the Prototype ļæ½Test & Create the Project
Follow your plans & drawings
Revise if necessary during prototyping
Does it work as anticipated?
Does it meet all criteria and constraints?

8 - Redesign or Refine
If it works, improve it.
If it doesnāt work, redesign it.
What went wrong? How can we fix the problem?
