EDD Project Development Flow Chart
• The flow chart provides an overall glimpse of the activities in EDD.
• There may be times when you will need to adjust or redefine your problem and revisit previous steps.
The 10 Mighty Questions
• Consider these questions.
• Return to these questions periodically during the course.− Provide focus− Provide direction− Provide perspective
Tools for Success
Validated, justified, well worded Problem Statement
All Current and Past Solutions
Solution #1
Pros and Cons
Solution #2
Pros and Cons
Solution # ?
Pros and Cons
Option 1 – Improve an existing solutionOption 2 – Combine one or more solutions to increase the overall success rate Option 3 – Invent a new or unique solution
NOTE: A project can be started here as long as justification for the solution’s existence can be supported. (Reverse Engineering)
Handout from Lesson 1.1
A Road Map to EDD
How well does it work? Why is it not perfect?
Justify the merit for attempting your solution and Create a prototype of your idea
Define and Create an accurate means of testing the prototype, simulation, process, mock-up or plan
Evaluate the DATA
Significant Improvement? Little or No Difference? Failure
Present your findings and make a judgment on what to do with the results

Rule of Thirds
Tool for Success
Keys to Success
• Identify a common area of interest among group members
• Act like a professional• Know your topic• Follow a project schedule• Maintain organization
– Engineering notebook, three ring binder, journal, portfolio, etc.
• Document everything

Keys to Success
Let the research drive the solution• Physical device• Process
Consider alternate solution paths•Modify an existing solution to produce better results (Innovation)•Combine design features of two or more existing solutions (Innovation)•Create a totally unique solution (Invention)

A Better Crutch
“When he brought his project in and demonstrated it to the class, he
showed that it could be easily adjusted for different body weights. It was
well conceived, durable and functioned effectively. It was just a
beautiful thing.”Greg Cisewski

A Better Way to Train for Cross Country
Skiing
Adam MartinEast High School
“The results of our new product assessment indicated that Adam’s idea was commercially feasible,”….. “we referred Adam to the Law and Entrepreneurship Clinic at the University of Wisconsin’s School of Law in Madison for that assistance. The clinic agreed to accept Adam as a client and will help him with the next steps in the commercialization process.”

The EDD Development Flow Chart
Flowchart Key:
• Perform research• Interview experts• Survey consumers• Write Specifications• Test a Concept• Create a schedule• Create sketches • Create technical
drawings• Perform a cost
estimate• Build a prototype• Test the prototype• Optimize your design• Document your work• Present your solution
Use the engineering design process to find a solution
