Ethics

SPIRIT
The meaning of ETHICS
 The
discipline dealing with what is
good and bad and with moral duty
and obligation.
 A set of moral principles or values
 A theory or system of moral values
 The principles of conduct governing
an individual or group
 Moral: of or relating to principles of
right or wrong in behavior

SPIRIT
Professional Ethics
 Lessons
learned at home, in school
and churches, mosques,
synagogues, or temples may not
provide enough explicit advice about
professional situations.
 If everyone's individually-learned
lessons were sufficient, why would
we need lawyers?
 Professional ethics involves
obligations to many stakeholders.

SPIRIT
Ethics in Engineering Design
 Engineering
work affects public health
and safety.
 Engineering can effect business practices
and politics.
 Personal ethics – how we treat others day
to day
 Professional ethics – deals with problems
at an organizational level.
 Two corporations
 Corporation and government
 Corporation and groups of individuals – the public

SPIRIT
Ethics and Design
 Ethics
problems are like design
problems
Open-ended, non-formulaic
No unique, correct answer
 Both
apply a large body of
knowledge to the solution of the
problem.
 Both involve the use of analytical
skills.
 Both use heuristics for the search.

SPIRIT
Ethics in Engineering Design
 Design
is a social activity
 Design involves PEOPLE
design team members
clients
manufacturers
USERS
 Designing
means accepting
responsibility for creating a design
for PEOPLE to use.

SPIRIT
The Prime Directive
The
prime directive in
American engineering ethics
is that Engineers shall hold
paramount the safety, health
and welfare of the public in
the performance of their
professional duties.

“Code of Ethics” of the National Society for Professional Engineers.
SPIRIT
Engineering Societies
 Set
 Set
design standards
ethical standards addressing
conflicting obligations and their
resolution
 Provide mechanisms for helping
engineers investigate and evaluate
ethical behavior
 A Professional Society's Code of Ethics
addresses standards of behavior with
respect to
clients
the profession
the public
the law

SPIRIT
IEEE Code of Ethics
We, the members of the IEEE, in
recognition of the importance of our
technologies in affecting the quality
of life throughout the world, and in
accepting a personal obligation to
our profession, its members and the
communities we serve, do hereby
commit ourselves to the highest
ethical and professional conduct and
agree:
10
SPIRIT
IEEE Code of Ethics
 To
accept responsibility in making
engineering decisions consistent
with the safety, health, and welfare of
the public, and to disclose promptly
factors that might endanger the
public or the environment;
 To avoid real or perceived conflicts
of interest whenever possible, and to
disclose them to affected parties
when they do exist;
11
SPIRIT
IEEE Code of Ethics
 To
12
be honest and realistic in stating
claims or estimates based on available
data;
 To reject bribery in all its forms;
 To improve the understanding of
technology, its appropriate application,
and potential consequences;
 To maintain and improve our technical
competence and to undertake
technological tasks for others only if
qualified by training or experience, or after
full disclosure of pertinent limitations;
SPIRIT
IEEE Code of Ethics
 To
13
seek, accept, and offer honest
criticism of technical work, to
acknowledge and correct errors, and to
credit properly the contributions of
others;
 To treat fairly all persons regardless of
such factors as race, religion, gender,
disability, age, or national origin;
 To avoid injuring others, their property,
reputation, or employment by false or
malicious action;
SPIRIT
IEEE Code of Ethics
 To
assist colleagues and co-workers
in their professional development
and to support them in following this
code of ethics.

SPIRIT
Is it OK for me to be working on this project?
 Design
of a cigarette lighter
 Design of cigarette-making
machinery
 Design of large scale ovens and
their specialized buildings in
Germany in the 1930s and 1940s
 Design of nuclear weapons
 The answer: It depends.
15
 We can only hope that we are prepared by our
upbringing, our maturity, and our ability to think
and reflect about the issues.
SPIRIT
Heuristics
A
heuristic is anything that provides
a plausible aid or direction in the
solution of a problem.
 Heuristics are usually unjustified and
potentially fallible.
 Engineering design is the use of
heuristics.
 Heuristics are used to cause the best
change in a poorly understood
situation within the available
resources.

SPIRIT
Concurrent Engineering
Design
teams include others in
addition to engineers
Manufacturing experts
Marketing and sales professionals
Reliability experts
Cost accountants
Lawyers
Concern
18
with all these areas and
their impact on the design is
concurrent engineering.
SPIRIT
-ilities
 Concurrent
engineering demands
consideration of the complete life
cycle of the product, process, or
project.
 Design for:
Manufacturability
Affordability
Reliability
Sustainability
Quality
19
SPIRIT
Can this Design Be Made? (DFM)
 The
design of a product has an
ENORMOUS impact on its
manufacture.
 A basic DFM methodology
Estimate the cost for a given alternative
Reduce the costs of components
Reduce the costs of assembly
Consider the effects on other objectives
If not acceptable, revise the design
REPEAT …
20
SPIRIT
Design for Assembly (DFA)
Limit
the number of components
Using standard components
Use a base component on which
other components can be
located
Use components the facilitate
retrieval and assembly
Maximize accessibility during
manufacturing and maintenance
21
SPIRIT
Affordability
Engineering
Economics
The time value of money
Money obtained sooner is more
valuable than money obtained later.
Money spent sooner is more costly
than money spent later.
Design decisions made today will
translate into streams of “financial
events” in the future.

SPIRIT
Arthur M. Wellington’s
definition of engineering
“the art of doing that
well with one dollar
which any bungler
can do with two.”
23
SPIRIT
Reliability
 To
an engineer: the probability that
an item will perform its function
under stated conditions of use and
maintenance for a stated measure of
a variate.
 Incidental failure
 Catastrophic failure
 Maintainability
Parts easily accessed and repaired
Redundancy
24
SPIRIT
Sustainability
 One
generation’s progress can be the
next’s nightmare.
 Environmental responsibility is
incorporated directly into the ethical
obligations of engineering.
 Air and water quality
 Energy consumption
 Disposal
 Life
cycle assessment analysis
 Inventory
 Impact
 Improvement
25
SPIRIT
Design for Quality
of the –ilities are components of
the design for quality
 A quality design satisfies all
constraints
 All
Fully functional within the performance
specifications
Meets the objectives as well or better than
alternative designs
 All
the work of the design process is
directed to design for quality.
