2. What is an Engineer? Engineers apply science and technology to
develop solutions to practical problems–problems
that need to be solved for the benefit of humanity.

3. ABET Definition “Engineering is the profession in which a knowledge of
the mathematical and natural sciences, gained by study,
experience, and practice, is applied with judgment to
develop ways to utilize, economically, the materials and
forces of nature for the benefit of mankind”

4. Working Definition Engineering as an activity:
An innovative and methodical application of scientific
knowledge and technology to produce a device, system
or process, which is intended to satisfy human needs.

5. Are Engineers Inventors?
Seek to develop a new idea
Do not necessarily apply scientific knowledge and follow methodical approach
Engineers:
Seek to solve a specific technical problem
Always applies scientific knowledge and follows methodical approach
Many engineers are also inventors

6. Attributes of an Engineer
Problem solving skills
Effective communication skills
Highly ethical and professional behavior
An open mind and positive attitude
Proficiency in math and science
Technical skills
Motivation to continue learning
Knowledge of business strategies and management practices
Computer literacy
Understanding of world affairs and cultures

7. Engineering Design Process
Needs
Assessment
Implementation
Iteration
Problem
Formulation
Analysis
Abstraction
And Synthesis

8. Needs Assessment Identify the objective(s)
Identify who will benefit from the solution
Begin with the end in mind: know where you are going.

9. Problem Formulation Define problem in terms of Design Goals:
Check your premises
Structure search for solution: many different solutions
Acquire necessary technical knowledge
Identify design specs
Identify resources (time, money, personnel)
Prioritize design goals

10. Abstraction and Synthesis
Develop conceptual solutions
Generate detailed alternative solutions
Be creative

11. Analysis Compare and evaluate alternative designs
Establish objective evaluation criteria
Eliminate “poor” alternatives
Select “best” design

12. Stakeholder Input Implementation Develop final solution
Obtain feedback for next-generation design
Stakeholder Input

13. Nth Generation Design
There is no such thing as a perfect solution to an engineering problem
The search for a better Nth-generation design solution to a problem may continue endlessly

14. Current Practices in Engineering Design
Life-cycle design
Design for manufacture and assembly
Design for quality
Faster design cycles
Engineering without walls
Design for export
