The Engineering Design Process

The Engineering Design Process is shown above

1. Identify a Need
2. Preliminary Design
3. Conceptual Design
4. Final Design
5. Manufacture
6. Sales & Delivery

1.Identify a Need
Quality Function Deployment Develop Product Specifications
· Product Functions
· Design Requirements
· Design Criteria
2.Preliminary Design
Idea Generation/Brainstorm
Development of Concepts
Decision Analysis
Design Review

3.Conceptual Design
Dimensional Modeling (CAD/Solids)
Material Selection
Analysis/Calculations
Initial/Basic Testing
Design Review

4. Final Design
Failure Modes Effects Analysis
Manufacturing Process & Flow
Detail Drawings
Prototype Testing
Design Review

5.Manufacture
Support Product Launch
Observe Quality
· Adherence to part tolerances
· Performance of product

6.Sales & Delivery
Delivery Package Design
Solicit Customer Feedback
Continuous Improvement

Failure Modes and Effects Analysis (FMEA):
· A design tool used to:
o Critique a design
o Identify potential failures and
their effects on the product.
o Reduce the incidence of
problems
o Inexpensively implement
changes. (Pareto 80/20 rule)
· Can be used on a component or an
entire product.
· It is completed on a standard form.
