ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 1
Chapter 1: Introduction
1.1 Background Ideas
Ethical cases can go far beyond issues of public safety. It may involve bribery, fraud,
environmental protection, fairness, honesty in research and testing and conflict of
interest.
Ethical problems will be faced by engineers throughout their professional practice.
Hence, ethical choices must be made.
Definition of ethics and engineering ethics;
Ethics = study of characteristics of morals deals with moral choices made by each person
in his or her relationship with other persons.
Engineering ethics = rules and standards of governing the conduct of engineers in their
role as professionals.
In other words, engineering ethics is a body of philosophy indicating ways that engineers
should conduct themselves in their professional capacity.
1.2 Why Study Engineering Ethics?
The work of engineers can affect the public health and safety and can influence business
practices and even politics. eg. FORD Pinto.
Fostering moral autonomy
moral autonomy = the ability to think critically (forming own opinion) and independently
about moral issues AND applying this moral thinking to situations that arise in the
professional engineering practice.
Not to train to do the right thing when ethical choices is obvious but to train how to
analyze complex problems and to learn to resolve these problems in the most ethical
manner.
1.3 Engineering is Managing the Unknown.
Lack of knowledge is not an unusual situation in engineering. Often many situations not
all information is known/available; as engineering design is about creating new devices
and products.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 2
Many questions need to be answered;
"How well does it work?"
"How will it affect people?"
"What changes will this lead to society?"
"How well does it work under all conditions that it will be exposed to?"
"Is it safe?"
"If there are some safety concerns, how bad are they?"
"What are the effects of doing nothing?"
As an engineer, you can never be absolutely certain that your design will never harm of
cause detrimental changes to society.
Test your design as thoroughly as time and resources permits.
Use creativity to attempt to foresee the possible consequences of your work.
1.4 Personal vs. Business Ethics.
Personal ethics = deals how we treat others in our day-to-day lives. Many of the
principles are applicable in business and engineering situations.
Business ethics = often involves choices on an organizational level rather than a personal
level. Involves relationships between two corporations, between corporation and the
government, or between corporations and groups of individuals. These problems very
seldom encountered in personal ethics.
In engineering ethics, we seek to go beyond the dictates of the law.
Our interest is in areas where ethical principles conflict and there is no legal guidance for
how to resolve the conflict.
1.5 Ethics Problems are Similar to Design Problems.
Ethics problems are open-ended, not as susceptible to formulaic answers.
types of problem solving techniques and the nature of the answers resembles engineering
design activity:
1. design of products, structure and processes
2. design problems is stated in terms of specifications i.e; performance, aesthetic,
costs.
Within the limits of the specifications, there are many correct solutions.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 3
In engineering design there is no unique correct answer.
Ethical problem solving shares these same attributes with engineering design.
1.6 Origins of Ethical Thought
Western ethical thought is developed through Judeo-Christian tradition thinkers from
ancient Greeks.
non-Western culture
religion
1.7 Ethics and the Law
Many laws are based on ethical principles
However, many things that are legal could be considered unethical
Example: designing a process that releases a known toxic, but unregulated, substance into
the environment is probably unethical although it is legal.
Conversely, just because something is illegal doesn't mean that it is unethical
Example: substances that were thought to be harmful, but have shown to be safe, that you
would like to incorporate into a product. If the law has not caught up with the latest
findings, it might be illegal to release these substances.

Chapter 2: Professionalism and codes of ethics
2.1 What is code of ethics
Code of ethics is the hallmark of modern professions.
But what is "profession"?
What is the difference between "job", "occupation" and "profession"?
Job/occupation = employment through which someone makes a living
"Professional athletes" depicts an athlete who is paid and distinguishes from the unpaid amateur
"Professional carpenters" indicates some degree of skill acquired through many years of
experience, with an implication that these practitioners will provide quality services.
Professional engineers?
Referring to the 1st case:
no amateur engineers who perform engineering work without being paid while they train
to become professional engineers.
Referring to the 2nd case:
If/When an engineering aide/technician has acquired even a high degree of skill, it does
not confer professional status.
Attributes of a profession:
1. Work that requires sophisticated skills, the use of judgment* and the exercise of
discretion**. The work is not routine and not capable of being mechanized.
2. Membership in the profession requires extensive formal education, not simply practical
training or apprenticeship
3. The public allows special societies or organizations that are controlled by members of the
profession to set standards for admission to the profession, to set standards of conduct for
members and to enforce these standards.
Significant public good results from the practice of the profession
* making significant (eg. involving huge sums of money) decisions based on formal training and
experience.
**confidentiality; trusting relationships and the ability to make decisions autonomously.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 5
2.2 Engineering as a Profession
Essence of engineering design is judgment: how to use the available
materials/components/devices etc, how to reach a certain specific objective.
Discretion: employers and clients intellectual property and business information
confidential.
Safety of the public that uses the products/devices he designs.
No mechanization of work
AUTOCAD, MULTISIM, MATLAB etc are tools to assists in engineering work.
Society consisting of the same profession IEEE, IEM, BEM.
Differences Between Engineering and Other Profession (Physicians and Lawyers)
Engineers Physicians/Lawyers
employed by larger companies involving
many different occupations (excluding civil
engineers)
self-employed (private practice) or larger
group practices with the same profession
four years of undergraduate education training starts after undergraduate
education
do not require license to practice must have license to practice
powerful professional society
higher social stature
If engineering were practiced more like medicine:
Four years of "pre-engineering" degree in math, physics, chemistry, computer science etc.
3-4 years engineering professional program culminating in a "doctor of engineering"
degree which includes extensive study of engineering fundamentals, specialization in a
field of study and "clinical training".
Pattern of employment:
In engineering firms (similar to how civil engineers work) as consultants for
government agencies or large corporations.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 6
Fewer engineers on payroll, the corporate rather employs a few professional
engineers to supervise several less highly trained engineering technicians.
Higher earnings.
Models of Professions
2.3 Codes of ethics
Express the rights, duties and obligations of the members of the professions.
Can also be found not only in professional organizations but also in corporations and
universities.
Provides a framework for ethical judgment for a professional.
Code of ethics is not a legal document
one can’t be arrested for violating it,
one may be expelled from the professional society/organization but still may practice
engineering.
A code helps the engineer to apply moral principles to the unique situations encountered
in professional practice.
SOCIAL CONTRACT
MODEL
society grants the profession
perks such as:
high pay
high status
ability to self-regulate
in return, society gets the
services provided by the
profession
BUSINESS MODEL
furthering the economic advantages of
the members (professional organization
are labour unions for the elite)
strictly limiting the numbers of
practitioners
controlling the working conditions
artificially inflating the salaries of its
members
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 7
HOW?
1) Helps create an environment within a profession where ethical behavior is the
norm.
2) A backup for an individual who is being pressured by a supervisor to behave
unethically.
3) Indicate the profession is seriously concerned about responsible professional
conduct.

SEMESTER 1 - 2013/2014 Page 8
Chapter 3: Understanding ethical problems
Ethical theories help us to understand and solve ethical problems. Ethical theory is a
comprehensive perspective on morality that clarifies, organizes and guide moral reflection. It
also provides a framework for making moral choices and resolving moral dilemmas.
There are a large number of ethical theories. This doesn't indicate a weakness in theoretical
understanding of ethics or a fuzziness of ethical thinking. Rather, it reflects the complexity of
ethical problems and the diversity of approaches to ethical problem solving.
The Five main ethical theories are UTILITARIANISM, RIGHT ETHICS, DUTY ETHICS,
VIRTUE ETHICS and SELF-REALIZATION ETHICS.
3.1 Utilitarianism
Maximize the overall good, taking into equal account all those affected by our actions for
example building of dams which can provide drinking water, electricity, flood controls,
recreational opportunities and many more.
But benefits come at the expenses of people (and animals) living in the areas where it will be
flooded. Animals which are probably endangered species. This theory tries to balance the needs
of society with the needs of the individual, with an emphasis on the most beneficial to the most
people.
Case studies : Bhopal Disaster, WIPP New Mexico
Utilitarianism has two versions:
3.1.1 Act-utilitarianism
Individual actions should be judged based on the most good produced even if the moral
rules should be broken.
3.1.2 Rule-utilitarianism
Says that moral rules must be adhered at all times.
Was developed primarily as a way of correcting several problems with act-utilitarianism.
Example 1:
Act-utilitarianism apparently permits some actions that we know are patently immoral.
Suppose that stealing a computer form my employer, an old one scheduled for replacement
anyway, benefits me significantly and causes only miniscule harm to the employer and
others. We know that theft is unethical, and hence act-utilitarianism seems to justify
wrongdoing. Rule-utilitarianism express this moral knowledge by demonstrating the overall
goods is promoted when engineers heed the principle, Act as faithful agents or trustees of
employers.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 9
Example 2:
Suppose company morale would greatly improved if several disliked engineers are being
fired after being blamed for mistakes they did not make. Doing so is unfair, but the overall
good is promoted.
Cost benefit analysis
A tool in engineering analysis to help determined whether a project has the highest ratio
of benefits to costs. eg. Ford Pinto.
In this analysis, it is important to determine who reap the benefits and who will pay the
costs. It’s unfair for a group to reap all the benefits while another group is the ones who
have to pay the costs.
In 1977, Mark Dowie published an article in Mother Jones magazine that divulged the
cost-benefit analysis developed by the Ford Motor Company in 1971 to decide whether to
add an $11 part per car that would greatly reduce injuries by protecting the vulnerable
fuel tank that explodes in rear-end collisions under 5 miles per hour. The $11 seems an
insignificant expense, even judging to current dollars, but in fact it would make it far
more difficult to market a car that was to be sold for no more than $2000. Moreover, the
costs of installing the part on 11 million cars and another 1.5 million light trucks added
up. The cost of not installing the part and instead paying out the costs for death and
injuries accidents was projected using a cost-benefit analysis. The analysis estimated the
worth of a human life at about $200,000, a figure borrowed form the National Highway
Traffic Safety Administration. The cost per non-death injury was $67,000. These figures
arrived at by adding together such costs as a typical worker’s future earnings, hospital
and mortuary costs and legal fees. In addition, it was estimated that about 180 burn
deaths and another 180 serious burn injuries would occur each year. Multiplying these
numbers together, the annual costs for death and injury was $49.5 million, far less than
the estimated $137 million for adding the part, let alone the lost revenue from trying to
advertise a car for uninviting figure of $2,011, or else reducing profit margins.
Ford’s cost-benefit analysis is usually understood to be utilitarian calculation. However
the calculations were seriously flawed. The death and injuries turned out to be more than
were estimated-Dowie estimated 3000 per year. Also juries awarded larger damage
verdicts once Dowie’s article appeared. The negative publicity Ford received greatly
damaged its reputation and adversely affected all of its sales for a decade.
Even if the cost-benefit analysis was accurate, it was not totally utilitarianism. It
implicitly focused on the costs and benefits to Ford Motor Company. In particular, it
omitted the bad consequences of not informing consumers of known dangers. It
calculated the costs in the short run, for each year, rather than the long run. Cost-benefit
analysis should have also taken into account additional good consequences such as
human happiness, instead of justifying the benefits in dollars.

New York: McGraw-Hill. 56;2005.)

SEMESTER 1 - 2013/2014 Page 10
3.2 Right Ethics
Is the respect towards human rights. Some of the example of human rights is privacy, not to
be injured, receiving benefits through fair and honest exchange, be informed about the risks and
safety of one's surrounding environment or products etc, liberty, livable environment, pursuit of
happiness, decent human life and many more.
There are also special moral rights, rights held by particular individuals rather than by every
human being.
For example, engineers and their employers have special moral rights that arise from their
respective roles and the contracts they make with each other. Thus, contracts and other types
of promises create special rights.
Another example is, when the public purchases products, there is an implicit
(understood/unspoken) contract that the products will be safe and useful.
Some rights are absolute, in the sense of being unlimited and having no justifiable
exceptions. For instance, if people purchase hang gliders and then injure themselves by flying
them carelessly or under bad weather conditions, their rights have not been violated—assuming
that advertisements about the joys of hang gliding did not contain misleading information.
But human rights does imply when people are injured or killed by products whose dangers
are not obvious or are deliberately hidden.
3.3 Duty Ethics
Is to respect individual's autonomy. Some of the examples of duty ethics is people deserve
respect because they are capable of recognizing and voluntarily responding to moral duty.
Autonomy = moral self-determination or self-governance, means having the capacity to
govern one’s life in accordance to moral duties.
Immorality occurs when we “merely use” others, reducing them to mere means to our ends,
treating them as mere objects to gratify our needs.
Violent acts such as murder, rape and torture are obvious ways of treating people are mere
object serving our purposes.
We also fail to respect persons if we fail to provide support when they are in desperate need
and we can help at little inconvenience to ourselves.
Of course we need to “use” others: business partners, managers and engineer, faculty and
students, to obtain personal and professional ends. Immorality involves treating persons as
mere means to our goals, rather than as autonomous agents who have their own goals.
It is a moral duty to do what is right because it is right, unconditionally and without special
incentives attached. For example, we should be honest because honesty is required by duty; it
is required by our basic duty to respect the autonomy of others, rather than to deceive and
exploit them.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 11
Golden Rule : Do unto others as you would have them do unto you; or, Do not do unto others
what you would not want them do to you.
Right and duty ethics are mirror images of each other
"You have the right to live, I have a duty not to kill you; and if I have a duty not to deceive
you, you have the right not to be deceived".
Rights Corresponding duties
Kelly has a right to life Others have a duty not to kill Kelly
Kelly has a right to free action Others have a duty not to coerce Kelly
Kelly has a right to free speech Others have a duty not to prevent Kelley
from speaking freely
Kelly has a right not to be deceived Others have a duty not to deceive Kelly
Kelly has a right not to be stolen from Others have a duty not to steal from Kelly
Kelly has a right to kept promises Others have a duty not to break their
promises to Kelly
Kelly has a right to nondiscrimination
Others have a duty not to deny Kelly
opportunities based on race, gender, creed
or sexual preferences
Kelly has a right o property
Others have a duty not to bar Kelly
opportunities for free and fair competition
for property and its use
3.4 Virtue ethics
Is about good character and always based to morality. Virtue ethics emphasizes character
more than rights and rules. Example of virtue; competence, honesty, courage fairness, loyalty,
humility. In engineering, the most comprehensive virtue is responsible professionalism. This
implies four categories of virtue:
3.4.1 Public-spirited virtues
Engineering codes of professional conduct call for beneficence, which is preventing
or removing harm to others and promoting public safety, health and welfare.
Sacrificing time, talent and money to their professional societies or local
communities.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 12
3.4.2 Proficiency virtues
Mastery of one’s profession, being well-prepared
Diligence: alertness to dangers and careful attention to details
Creativity
3.4.3 Teamwork virtues
Important in enabling professionals to work successfully with other people.
Teamwork virtues include collegiality, cooperativeness, loyalty and respect for
legitimate authority.
A leadership quality is an important key role within authority-structured corporations,
such as responsible exercise of authority and ability to motivate others.
3.4.4 Self-governance virtues
Necessary in exercising moral responsibility, for example self-understanding and
good moral judgment-what Aristotle called practical wisdom.
Also commitment and on putting understanding into action for example, courage,
self-discipline, perseverance, fidelity to commitments, self-respect and integrity.
3.5 Self-realization ethics
Is about moral significance of self-fulfillment
Self identity and meaning are linked to the communities in which we participate. Self-
realization ethics points to the particular commitments that individuals make in their
work, as well as in their professional lives. It is a central theme of how personal
commitments motivate, guide and give meaning to the work of engineers and other
professionals. Personal commitments are relevant in many ways to professional life, they
create meaning; thereby they motivate professionalism throughout long careers.
Example :
During the 1950’s the miniaturization of transistors was being pursued a t a relentless
pace, but it was clear there would soon be a limit to the vast number of minute
components that could be wired together. Jack Kilby, was well aware of the problem and
sensed the need for fundamentally new approach. In July 1958, only a few weeks after
starting a new job in Texas Instruments, he discovered the solution: make all parts of the
circuit out of one material integrated on a piece of silicon, thereby removing the need to
wire together miniature components. Thus the microchip was born. The invention has had
a momentous importance in making possible the development of today’s powerful
computers. In 2000, Kilby was awarded a Nobel Prize. Was Kilby, merely seeking
money, power, fame or other rewards? As Jeffrey Zygmont (a biographer “Microhip”
pg.3) puts it “we see nothing extraordinary in Jack Kilby’s private ambition or in his aim
to find personal fulfillment through professional achievement. In that regard he was the
same as the rest of us : We all pick professions with a mind to fulfilling ourselves.”

(Martin, M.W & Schinzinge, R., Ethics in Engineering. 4th
edition.
New York: McGraw-Hill. 76;2005.)
Example :
Gene Moriarty reports that his first job after college was a large aerospace company.
“The engineers in prospective company were excited telling me about a system they were
developing. It sensed the terrain with an ingenious radar mechanism, employed an
elaborate feedback control structure, and made determinations on the basis of statistical
decision rules. The job offered fascinating prospects for sophisticated engineering
designs. But then I took a wider look at the project and realized that the system I’d be
working on was to form part of the signal processing unit of what came to be the Cruise
Missile.” Moriarty decided not to pursue the job because, while it offered a “technically
sweet project”, since childhood he had believed that “war was good for nothing,
generally speaking, except making the rich people richer.”
(Martin, M.W & Schinzinge, R., Ethics in Engineering. 4th
edition.
New York: McGraw-Hill. 78;2005.)
Another example is more dramatic, chronicled by Loren R. Graham in The Ghost
of the Executed Engineer (1993) is the courageous and creative life of Peter
Palchinsky who literally sacrificed his life for his ideals.
Personal religious beliefs (religious commitments) also have relevance to the
professional lives of many engineers.
Although the fear of punishment in the afterlife or bad karma and such, are
usually associate with religious commitments, but it also allure inspiration rooted
in religious faith. In addition, religions sometimes set a higher moral standards
than the conventional.
For example, the ethics in Christianity centers on the virtue of hope, faith and
love; Judaism emphasizes the virtue of tsedekah(righteousness); Buddhism
emphasizes compassion; Islam emphasizes ihsan(piety or the pursuit of
excellence); Navajo ethics centers on hozho(harmony, peace of mind, health,
beauty or well-being).
Mark Pesce is the principal engineer for Shive Corporation, which invented dial-
up networking. In 1994, Pesce and a colleague developed the Virtual Reality
Modelling Languange (VRML), which allowed three-dimensional models top be
placed on the World Wide Web (Reid, R.H Architects of the Web. John Wiley &
Sons.167-209:1997).Emphasizing the importance of spiritual attitude in his
work, he makes it clear that his beliefs are neither orthodox nor associated solely
with any one world religion. He characterizes his belief as “a mélange of a lot of
different religious traditions including Christian, pre-Christian, Buddhist, Taoism
ad so on,” integrated into a type of “paganism” which is a practice of harmony, a
religion of harmony with yourself and the environment.
(Martin, M.W & Schinzinge, R., Ethics in Engineering. 4th

Chapter 4: Ethical problem-solving techniques
Issues involved in any ethical problems must first be determined. The issues can be split into
3 categories which is factual, conceptual and moral.
4.1 Factual issues
Involve what is actually known about a case; what are the facts. Facts are usually clear-cut,
but sometimes facts can be blurry and may be controversial.
eg.
a) abortion-at what point life starts (Roe vs. Wade)
b) global warming-what is the process and how does greenhouse gasses affect the
atmosphere
Factual issues can often be resolved through research to help establish the "true" facts, hence
clarifying the situation.
4.2 Conceptual issues
have to do with the meaning or applicability of an idea
eg. defining what constitutes a bribe as opposed to an acceptable gift.
The value of the gift is a probably a well-known fact.
BUT, conceptually is the gift meant to influence your decision or it is merely a nice gesture
between friends. Conceptual issues are resolved by agreeing on the meaning of terms and
concepts.
4.3 Moral issues
Are resolved by agreement as to which moral principles are pertinent (relevant) and how they
should be applied.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 15
Chapter 5: Risk, Safety and Accidents
No duty of the engineer is more important than her duty to protect the safety and the well-
being of the public. Where by Risk = the possibility of suffering harm or loss and Safety =
freedom from damage, injury or risk. “We engage in risky behavior when we do something that
is unsafe, and something is unsafe if it involves substantial risk". Safety and risk are essentially
subjective and depends on many factors;
1) Voluntary vs. involuntary risk -many consider something safer if they knowingly take on the
risk, but would find it unsafe if forced to do so.
2) Short-term vs. long-term consequences -fractured leg vs. spinal fracture leading to permanent
disability.
3) Expected probability -swimming at a beach with large concentration of jellyfish
(unacceptable) vs. beach with a low enough risk of shark attack (acceptable).
4) Reversible effects.
5) Threshold levels for risk -automobile accident vs. nuclear radiation.
6) Delayed vs. immediate risk -high-fat diet vs. skydiving.
The question of how safe is something depends on who is asked. Some may consider
something is safe but someone else may consider it unsafe. Ultimately, it is up to the engineer
and the company management to use their professional judgment to determine whether a project
can be safely implemented. Four criteria that must be met to ensure a safe design.
1) Comply with the applicable law - legal standards for product safety are published and easily
accessible.
2) Meet the standard of "accepted engineering practice".
3) Alternative designs are potentially safer must be explored.
4) Attempt to foresee potential misuses of the product by the consumer and must design to
avoid these problems.
Both prototypes and finished devices must be rigorously(carefully and detailed) tested. These
tests should not only determine whether the product meets the specifications, BUT also to test
the safety of the product. eg. Russian navy submarine, The Kursk. Safety in engineering design
process;
1) Define the problem -determine the needs and requirements and constraints.
2) Generate several solutions (multiple alternative design).
3) Analyze each solution to determine the pros and cons of each. Determining the
consequences of each design solution and determining whether it solves the problem.
4) Test the solutions.
5) Select the best solution.
6) Implement the chosen solution.
Many of the risks are can only be expressed as probabilities and often are no more than
educated guesses. The prudent (careful and sensible) approach to minimizing risk in a design is a
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 16
"go slow" approach. However this approach isn't always in the real world. Often it’s because of
time and money constraints.
Risk-Benefit Analysis
Similar to cost-benefit analysis. Risks and benefits are assigned to money values. However,
risks are harder to quantify and more difficult to put a price tag on. In this analysis, one must
consider who takes the risks and who reaps the benefits. It is important to be sure that those who
are taking the risks are also those who are benefiting.
Accidents
Accidents can be grouped into three types ;
1) Procedural
The result of someone making a bad choice or not following established procedures.
these problems can include failure to adequately examining drawings before signing off
on them, failure to follow design rules or failure to design according to accepted
engineering practice.
can be reduced through increased training, more supervision, new laws or regulations or
closer scrutiny(careful and thorough examination) by regulators.
2) Engineered
Caused by flaws in the design.
failures of materials used, devices that don't perform as expected or devices that perform
well under all circumstances encountered.
these problems can be understood and alleviated (reduce) as more knowledge is gained
through testing and actual experience in the field.
3) Systemic
One of the characteristics of very complex technologies and the complex organization that are
required to operate them.
eg. airline industry
At many stages in the operation of an airline, there are many chances for mistakes to
occur. Often, a single minor mistake isn't significant, a series of small errors are not
significant alone. But when these small errors come together, a major accident can be
inevitable (impossible to avoid).
this type of accident is harder to understand and harder to control thus it is difficult to
take systemic accidents into account during design.
as engineers, it is important to understand the complexity of the systems involved, and to
attempt to be creative in determining how things can be designed to avert as many
mistakes by people using the technology as possible.
as designers, engineers are responsible for being thorough and careful in generating
owner's manuals and procedures.

SEMESTER 1 - 2013/2014 Page 17
Chapter 6: The rights and responsibilities of engineers
The code of ethics of the professional engineering societies mainly spells out the
responsibilities of an engineer. In this chapter, responsibilities of an engineer will be discussed
further. Also, the professional rights engineers can exercise, especially when faced with issues of
conscience and conflicts with the rights of employees or clients.
6.1 Professional responsibilities
6.1.1 Confidentiality and Proprietary Information
A hallmark of the profession is discretion. It is required that the professional keep certain
information of the company/employee and clients secret or confidential. This is practiced in
patient-doctor, client-attorney relationships also company/employee-engineer relationships.
The reason:
Most information about how a business is run, its products, suppliers directly affects the
company’s ability to compete in the marketplace. Competitors may use by such information
to gain advantage and to catch up. Hence, it is in the company’s/employee’s best interest to
keep such information confidential. Otherwise, it is very difficult to compete and stay ahead
of the herd. Engineers working for a client are frequently required to sign a nondisclosure
agreement. Engineers working for the government especially in the defense industry have
even more stringent requirements about secrecy placed on them and may even require a
security clearance granted after investigation by a governmental security agency before being
able to work.
Types of confidential information:
Obvious information such as;
Test results and data, information about upcoming unreleased products, and designs or
formulas for products.
Not so obvious information such as;
Number of personnel working on a certain project, identity of suppliers, marketing strategies,
production costs and production yields.
A common problem that often arises is, how long confidentiality extends after an
engineer leaves employment with a company. When an engineer moves to another company
in the same technical area, she brings a long with her experiences and a great deal of
knowledge. She knows what works, what materials/components to use etc. Legally, this is
considered as company’s confidential information. But, it is extremely difficult for an
engineer to forget everything she has learnt. However, it is the right of an individual to seek
career advancement wherever they choose and it is also the company’s right to keep
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 18
information away from competitors. The burden of ensuring that both of these competing
interests are recognized and maintained lies with the individual engineer.
6.1.2 Conflict of Interests
A conflict of interest arises when an interest, if pursued, could keep the engineer from
fulfilling her obligations.
Three types of conflict of interests:
1) Actual conflict of interests
e.g.
A civil engineer working for a state department of highways might have a financial
interest in a company that has a bid on a construction project. If that engineer has some
responsibility for determining which company’s bid to accept, then there is a clear
conflict of interest.
Pursuing his financial interest in the company might lead him not to objectively and
faithfully discharge his professional duties to his employer, the highway department.
2) Potential conflict of interests
e.g.
an engineer befriended the supplier of her company. Although this situation doesn’t
necessarily constitute a conflict, but there is the potential that the engineer’s judgment
might become conflicted by the needs to maintain the friendship.
3) Appearance conflict of interests
e.g.
An engineer paid based on a percentage of the cost of the design. There is clearly no
incentive to cut costs in this situation and it may appear that the engineer is making the
design more expensive simply to generate a larger fee.
To avoid conflicts of interests is to follow the guidance of company policy or asking a
coworker or manager. You may also look to the statement of the professional codes of ethics,
with explicit statements that can help determine whether or not your situation is a conflict of
interest.
6.1.3 Environmental Ethics
Engineers are responsible in part for the creation of the technology that has led to damage
of the environment. Engineers are responsible to use their knowledge and skills to help
protect the environment and also find solutions to the problems caused by modern
technology. Humans are just one component of the environment and that all components
have equal rights. It is an utmost duty of everyone to do what is required to maintain healthy
biosphere for its own sake.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 19
Several approaches to resolve environmental problems:
6.1.4 Cost-oblivious approach
Cost is not taken into account in keeping the environment as clean as possible. No level
of environmental degradation is seen as acceptable. This approach is difficult to uphold
especially in a modern urbanized society. The definition “as clean as possible” is hard to
agree upon. Being oblivious to cost isn’t practical in any realistic situation, in which there are
not infinite resources to apply to a problem.
6.1.5 Cost-benefit analysis
Here the problem is analyzed in terms of the benefits derived by reducing the pollution-
improving human health, for example. Costs, is the costs required to solve the problem. The
costs and benefits are weighed to determine the optimum combination, a balance of pollution
with health or environmental considerations.
Problems arise in determining the cost of a human life, the loss of a species or a scenic
view. This approach doesn’t necessarily take into account who shoulders the costs and who
reaps the benefits.
For an engineer, the minimal requirement is that the engineer must follow the applicable
federal, state and municipal laws and regulations.
Engineers do have the right o express their opinions on environmental issues. An
engineer should not be compelled by his employer to work on a project that he finds ethically
troubling, including projects with severe environmental impacts.
For many environmental issues, engineers aren’t competent to make decision but should
seek the counsel of biologists, public health experts and physicians or anyone with the
knowledge and authority in helping to analyze and understand the possible environmental
consequences of a project.
6.1.6 Computer Ethics
Computers have become a ubiquitous tool in engineering and business. Unfortunately,
there are numerous ways computers are misused, leading to serious ethical issues. It is the
engineer’s duty as a designer, manager and user of computers, to help foster the ethical use of
computers.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 20
6.2 Computers as the Instrument of Unethical Behavior
a) Theft
Computers as a tool to assist theft. Stealing whether by way of the traditional way or
simply by sitting in front of a computer, the ethical issues and law is not altered.
b) Invasion of privacy
Privacy = basic right of an individual to control access to and use of information about
himself. Information (individuals or corporate) gained without consent is an invasion of
privacy. With computers, protecting privacy has become much more difficult. Records
have been computerized, making retrieval of files much easier, it also makes the
unauthorized retrieval of this information by others easier. Invasions of privacy can lead
to an individual being harassed or blackmailed. Harassed in the simplest form, repeated
phone calls from telemarketers who have obtained information about an individual’s
spending habits. Subtle teasing or bothering from a coworker who has gained personal
knowledge of the individual. Personal information is considered as personal property.
This same principle applies to proprietary information of a corporation.
c) Hacking
Gaining unauthorized access to a database, implanting false information in a database or
altering existing information and disseminating viruses over the internet. In most cases of
hacking, hackers simply testing and pushing their skills and knowledge limits. In extreme
cases, secret military information is illegally accessed which may jeopardize national
security. Altering information may lead to fraud. Issuance of computer viruses may lead
to deaths when hospital records or equipment are compromised, financial ruins for
individuals whose records are wiped out, or the loss of millions of dollars for
corporations, individuals, taxpayers, as completed work must be redone.
6.3 Autonomous Computers
Refers to the ability of a computer to make decisions without the intervention of
humans. These computers benefit greatly in e.g. manufacturing process that require
monitoring at frequent intervals. However, some of the negative implications of this
autonomy are chillingly spelled out in 2001: A Space Odyssey by Arthur C. Clarke
which an autonomous computer responsible for running a spaceship headed for Jupiter
begins to turn against the humans it was designed to work for. This is also depicted in
the 20th
Century Fox movie, I-Robot, where the mainframe overrides the human
programming of servant cyborgs making them turn against their owners. In a real, a less
malicious example occurred on the October 19, 1987. Computers at the time were
widely used to automate trading on the major U.S stock exchanges. These computers
were programmed to automatically sell stocks under certain conditions, among them
when prices drop sharply. When the Dow Jones Industrial Average (a widely used
market-price indicator) dropped by 508 points, a 22.6% drop in overall value of the
market. This led to the 1987 stock market crash, as these computers start selling stocks,
further depressing the prices, causing other computers to sell and so on until the major
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 21
market crash. Implications of autonomous computers are also heavily discussed with
regard to military weapons.
6.4 Computers Codes of Ethics
The codes acts as guidelines for the ethical use of computing resources but should never
be used as a substitute for sound moral reasoning and judgment.
6.5 Professional rights
The most fundamental right of an engineer is the right of professional conscience. This
also includes the right to refuse to engage in unethical behavior. In a clear case, where
engineers are asked to falsify a test result or fudge on the safety of a product.
It is less clear case for which the engineer refuses an assignment based on an ethical
principle that is not shared by everyone. For example, an engineer may refuse to work on
defense, military projects or environmental hazardous work if his conscience says such work
is immoral due to its implication on human life. Others may feel that this type of work is
ethically acceptable as the defense of our nation or other nations from aggression is a
legitimate function. Employers should be reasonably accommodating of that person’s
request.
6.6 Whistle blowing
Whistle blowing is the act by an employee of informing higher management or the public
of unethical or illegal behavior within the organization.
According to the codes of ethics, engineers have the duty to protect the health and safety
of the public, so in many cases, an engineer is compelled to blow the whistle on acts or
projects that harm these values.
Engineers have the professional right to disclose wrong-doing within their organizations
and expect to see appropriate action taken.
Two types of whistle blowing:
1) Internal whistle blowing
When an employee goes over the head of an immediate supervisor to report a problem to
a higher level of management. Or all the levels of management are bypassed, and the
employee goes directly to the president of the company or the board of directors. The
whistle blowing is kept within the company or organization.
2) External whistle blowing
When the employee goes outside the company and reports the wrongdoing to
newspapers or law-enforcement authorities.
ENGINEERING ETHICS (BENU 4853)
SEMESTER 1 - 2013/2014 Page 22
Either type of whistle blowing is perceived as disloyalty. However, keeping it within the
company is often seen as less serious than going outside of the company. Whistle blowing should
only be attempted if the following four conditions are met:
1) Need
There is no need to whistle blow on every unethical behavior. The employee must have a
sense of proportion. For example; if an accident occurs resulting in a small quantity of
toxic compound and clean up was immediate, there is obviously no need to notify higher
management or outside authorities. But if this type of incident happens repeatedly and no
action is taken to rectify the problem despite repeated attempts by employee to get the
problem fixed, then perhaps this situation is serious enough to warrant the extreme
measures of whistle blowing.
2) Proximity
The employee must have a firsthand knowledge of the unethical act. Hearsay is not
adequate. This also implies that the employee must have enough expertise to assess the
situation.
3) Capability
The employee must have a reasonable chance of success in stopping the harmful activity.
You are not obligated to risk your career and the financial security of your family if you
can’t see the case through completion and you don’t have the access to the proper
channels to ensure that the situation I resolved.
4) Last resort
Should only be attempted only if the there is no one else more capable or more proximate
to blow the whistle and if you feel that all the other lines of action within the context of
the organization have been explored and shut off.
You are obligated to blow the whistle when there is great imminent danger of harm to
someone if the activity continues and the four conditions are met. It is acceptable to blow
the whistle to protect the public interest, but not to exact revenge upon fellow employees,
supervisors, or your company.
There are four ways to prevent whistle blowing:
i. Strong corporate ethics culture (including ethics training for all levels of employees).
ii. Clear lines of communication within the corporation (openness of communication).
iii. All employees must have meaningful access to high-level managers in order to bring
their concerns forward (guarantee that there will be no retaliation).
iv. Willingness on the part of management to admit mistakes.

Chapter 7: Ethics in research and experimentation
Many engineers will become involved in research and experimentation in the course of their
academic and professional careers. Even engineers who are not employed in research
laboratories or academic settings can be involved in research and development of the unique
ethical issues that are encountered in research. This chapter will examine some of the unique
ethical issues that are encountered in research.
7.1 Ethics and research
Two major ethical issues related to research:
1) honesty in approaching the research problem
Avoiding preconceived notions about what the results will be, being open to changing the
hypothesis when such actions is warranted by the evidence, generally maintaining an
objective frame of minds.
2) honesty in reporting the results
Results must not be overstated, an accurate assessment and interpretation of the data must be
reported, avoiding the temptation to “massage” the data to gain rewards, tenure, fame, or the
desire to be the first with new results/products.
Important note :
There is a distinction between intentional deception and results of interpretations that are
simply incorrect.
Sometimes, results are published that, upon further research turn out to be incorrect.
This is not an ethical issue unless clarification of the results is never presented. Rather,
this issues indicates that great care must be taken before results are initially reported.
Ensure that proper credit is given to everyone who participated in the research project.
Fraud and deception in research are not only perpetrated by lower level scientist, there are
many examples of well-known and even Nobel-prize winning scientist who have lapses of
ethical judgment with respect to their research e.g. Robert Milikan, Nobel Prize winner in
physics. Analyzing ethical problems in research is similar to analyzing ethical problems that we
have mentioned in the previous chapters.
a) To determine the best ethical course in performing research and experiment is to consult
the codes of ethics of the professional societies.
b) Ethical theories can also be used in analyzing issues involving research.
ENGINEERING ETHICS (BENU 4853)

7.2 Pathological science
Self-deception in research is a frequent occurrence in many areas of science. It doesn’t imply
any intentional dishonesty, but only that the researcher comes to false conclusion based on lack
of understanding about how easy it is to trick yourself through wishful thinking and subjectivity.
This shows that a great deal of objectivity and care is required in the pursuit of research and
testing. Ultimately, the goal of research is not publicity and fame but rather the discovery of new
knowledge.
The following are the six characteristics of pathological science outlined by Irving Langmuir,
a well-known physicist at General Electric’s Research Laboratories:
1) The maximum effect that is observed is produced by a causative agent of barely
detectable intensity, and the magnitude of the effect is substantially independent of the
intensity of the cause.
This characteristic implies that it doesn’t matter how close the causative agent is or how
intense it is; the effect is the same. This practice goes against all known forces and
effects.
2) The effect is of a magnitude that remains close to the limit of detestability; or, many
measurements are necessary because of the low statistical significance of the results.
The problem here is that when things are at the edge of statistical significance or of
detestability, the tendency is to discard values that don’t “seem” right. To measure
anything at the edge of detestability requires a lot of data. With a lot of data to work
with, the measurements can be massaged to fit the conclusion that is being sought. In
fact, what often happens is that data are rejected on the basis of their incompatibility with
the preconceived theory, rather then on their true significance.
3) Claims of great accuracy.
4) Fantastic theories contrary to experience.
5) Criticisms are met by ad hoc excuses thought up on the spur of the moment.
6) Ratio of supporters to critics rises up somewhere to near 50% and then falls gradually to
oblivion.
