1. Ethics involves examining concepts of right and wrong conduct and applying philosophical reasoning to recommend moral rules of behavior. 2. Engineering ethics guides engineers to act with social responsibility for safety and to consider how their work impacts people. 3. Codes of ethics establish standards for engineers to act honorably and prioritize public welfare over other concerns in their work.

2. Ethics, also known as moral philosophy, is a branch of
philosophy that involves systematizing, defending, and
recommending concepts of right and wrong conduct.

3.  The creative application of scientific principles
to design or develop
structures, machines, apparatus, or
manufacturing processes, or works utilizing
them singly or in combination; or to construct
or operate the same with full cognizance of
their design; or to forecast their behavior under
specific operating conditions; all as respects an
intended function, economics of operation or
safety to life and property

9.  Is it ethical to start up a weapon improvement
project to stop Germany’s rise?
 Thousands of people worked in the Manhattan
Project without knowing the real goal of the
project. Ethic?
 With spying of Mr. Fuchs time changed. Ethic?
Decisions made by engineers usually have serious
consequences to people -- often to multitudes of people.
Ethics and ethical reasoning guide decision-making.

10. Study by Swiss Federal Institute of Technology-Zurich 800 cases of structural failure, 504 killed, 592
injured, millions of dollars in damage incurred. 10

12.  Study of human morality
 Determining values in human conduct
 Deciding the “right thing to do” - based upon a
set of norms
 In Engineering:
 dealing with colleagues
 dealing with clients
 dealing with employees
 dealing with “users’
 dealing with public
12

13.  Safety
 Acceptable risk
 Compliance
 Confidentiality
 Environmental health
 Data integrity
 Conflict of interest
 Honesty/Dishonesty
 Societal impact
 Fairness
 Accounting for uncertainty, etc.

14.  Ethics is part of engineering for two main
reasons.
a) Engineers need to be socially responsible when
building products and processes for society.
b) Social responsibility requires professional
responsibility.

15. 1. Who are the “stakeholders?”
2. What are the KEY statements (clues) in the
problem?
3. What are the legal considerations?
4. What are the possible actions to be taken?
(generate options)
5. Is there a clearly “right” action to be taken?
(evaluate options)

Current Codes of Ethics
 National Society of Professional Engineers: Code of ethics for engineers.
 The Engineering Code of Ethics: Principles and canons of engineer code of ethics.
 Software Engineering Code of Ethics: A brief copy of software engineering code of
ethics.

19. The Engineering Code of Ethics has three
components:
 The Fundamental Canons: which articulate the basic
components of ethical engineering.
 The Rules of Practice: which clarify and specify in
detail the fundamental canons of ethics in
engineering.
 Professional Obligations: which elaborate the
obligations that engineers have.

professional duties shall:
Hold paramount the
safety, health, and welfare of the
public.

26.  1. Boston Molasses Disaster
The Boston Molasses Disaster, also
known as the Great Molasses
Flood and the Great Boston
Molasses Tragedy, occurred on
January 15, 1919, in the North
End neighborhood
of Boston, Massachusetts in
the United States. A large
molasses storage tank burst, and a
wave of molasses rushed through
the streets at an estimated 35 mph
(56 km/h), killing 21 and injuring
150.

28. 1. Ethical issue: Did NASA take extra risks because of
pressure to maintain Congressional funding?
2. Ethical issue: Did Thiokol take extra risks because of
fear of losing its contract with NASA?
