What is Ethics?
Morality encompasses the first-order beliefs and practices about
good and evil by which we guide our behaviour.
Ethics is the second-order, reflective consideration of our moral
beliefs and practices (Hinman, 2003; Baura, 2006)
Meta-ethics: What is the meaning ofgood?
Normative Ethics: It develops theories and models for how we
ought to treat each other.
Applied Ethics: It centers on the resolution of scientific ethical
problems.

What is Engineering Ethics?
Engineering ethics is the study of the moral values,issues, and decisions involved in engineering practice
(Schinzinger & Martin, 2000)
Engineering ethics as much a part of what engineers in
particularly know as factors of safety, testing procedures,or ways to design for reliability, durability, or economy
(Harris, C.E., et al, 1996,p.93).
Engineering practices revolve around 03 variables; cost,
schedule, and quality. A little compromise in one
component affect others.

Who is a Professional?Criteria to consider someone as a professional (Sociological)
-- Extensive training
-- Vital knowledge and skills
-- Control of services
-- Autonomy in the workplace-- Know the ethical regulations (Harris, C., et al., 2003, pp.2-3)
Professional responsibilities for engineers
*** Concern for public safety
*** Technical Competence
*** Timely communication of positive and negative
results to management

Self-defense (may kill
others)
Moral permissible standardsof conduct that ideally every
member of a profession wants
every other member to follow,
even if that would mean
having to do the same (Harris,

Engineering Ethics & Some EthicalTheories
Utilitarianism
Duty Ethics
Rights Ethics
Virtue EthicsA fictional Situation:
-- A company, 01 CEO, 04 VPs (Executive Committee)
-- The VP of Engineering: manages the design andtesting of new product (Mr. Hariprasad)
-- The VP of Operation: is responsible for managing the
manufacture and delivery of products
7/22/2019 Professional Ethics (Lecture-1).ppt
12/31
Continue..-- Mr. Vivek (hardware manager-cum-engineer) and Mr.
Chandran (software manager-cum-engineer) need to
report to Mr. Hariprasad
-- Mr. Vivek is responsible for designing and testing the
electronic circuits along with his engineering staff.
-- Mr. Chandran has assigned the task of designing and
testing the software along with his engineering staff.
-- Mr. Vivek gave 03 information to the CEO
i) the email announcement of transfer was falseii) the product is still not ready to transfer
iii) A product recall may occur unless adequate testing is
completed.
7/22/2019 Professional Ethics (Lecture-1).ppt
13/31
Utilitarianism The morality of an action is decided based on the
assessment of its consequences.
Jerry Bentham: maximized pleasure and minimized pain
J.S.Mill: to maximize happiness & to minimize pain.
Uti l i tar ian Decisio n:
Mr. Vivek needs to pay a huge price for telling the CEO
that Mr. Hariprasad is wrong in his announcement.
This may ruined the relationship between Mr.Vivek and
Mr.Hariprasad. It may affect the relationship between the
CEO of the company and Mr. Hariprasad.
However, suppressing the information and not telling the
CEO may cost the company to bear a huge amount of
money as a compensation fee. Further, the customer will
get affected by it.
7/22/2019 Professional Ethics (Lecture-1).ppt
14/31
Continue.. Using utilitarianism, Mr. Vivek is obliged to tell the CEO that
the product is not ready to transfer to the manufacturingdepartment.
Duty Ethics:
Immanuel Kant is propounded this theory.
On his view, an action is moral:
If it is conducted for the sake of duty
If its maxim can be willed as a universal law
If it treats human beings respectfully.
--- Kant said that we need to treat others as an end, but never
simply as a means to an end.
--- For a maxim to be considered universal, it must be
consistent, impartial, and fair
7/22/2019 Professional Ethics (Lecture-1).ppt
15/31
Continue.. Duty Ethics Decis ion:
Mr. Vivek is bound by duty to protect the quality of the
products his company produces
The maxim of producing high quality products that are not
recalled may be considered universal.
Company customers deserve to receive high quality products
as it is advertised.
--- Using duty ethics, Mr. Vivek is obliged to tell the CEO that
the product is not ready to transfer to manufacturing unit. The
consequences of this action are immaterial.
Rights Ethics:
Rights and duties are inalienably related with each other.
One can claim his/her rights only when (s)he does his/her
duties.
7/22/2019 Professional Ethics (Lecture-1).ppt
16/31
Continue.. Negative duty (Misuse of right to free speech act)
Positive duty (Right to get the basic health care)
Natural rights (The supreme reality sanctions- come to us
with our birth, e.g. ability to think, reflecting on our decisions,
etc.)
Human rights (consciously earned by performing duties)
Right Ethics Decis ion s:
Mr. Vivek has the rights to tell the CEO that Mr. Hariprasad is
wrong about the product, much as Mr. Hariprasad had the
right to announce product completion by e-mail. The concept
of product recall is immaterial to this discussion. Using rights
ethics, Mr. Vivek is obliged to tell the CEO that the product is
not ready to transfer to manufacturing unit.
7/22/2019 Professional Ethics (Lecture-1).ppt
17/31
Continue..Virtue Ethic s:
Aristotle advocates this theory.
It says morality is not related to action, but to virtue.
Virtue is a quality of soul involving both feeling and action to
seek the mean in all the things related to us.
Virtue leads to happiness.
Virtue Ethics Decisio n:
Mr. Viveks concern were about the faulty product and the
consequences after its use by public
His courage(virtue) requires to tell the CEO about Mr.
Hariprasads decision (otherwise, it will be like RAY-Yamaha)
He seeks the mean between Mr. Hariprasad underestimation
of the danger of a recall and overestimation of this danger.

Five Questions about Engineering
ethicsWhat is engineering ethics?Why should it be emphasized in engineering
education?
How should it be taught?
When should it appear in the students
education?
Teaching engineering ethics is part of teaching
engineering.
7/22/2019 Professional Ethics (Lecture-1).ppt
19/31
Why should it be emphasized inengineering education?Long list of Disasters, tragedies, scandals
Something should be done to protect all these bad things
to happen- eruption of engineering ethics
Conscience is not enough to practice engineering andtake a decision
Engineering code of ethics
Learning from some of the unfortunate mistakes
Despite a few engineers misfortune immoral decisions,national surveys usually place engineers near the top of
the list in regard to the public confidence in the ethics of
profession (The Gallup Poll Monthly, 1992, p.3).

What should be the common goals
of engineering ethicseducation?To stimulate the ethical imagination of students
To assist students to recognise ethical issues
Conflict of interest vs. conflict of commitment
conflicting roles vs. conflicting obligationsTo help students to analyze the key ethical concepts and
principles that are relevant to the particular profession
Public health & safety, usefulness, efficiency, quality, cost-risk-
benefit analysis, damaging the environment, truthfulness, etc.To help students to deal with ethical disagreement,
ambiguity, and vagueness.
To encourage students to take ethical responsibility
seriously
7/22/2019 Professional Ethics (Lecture-1).ppt
21/31
Significance of teaching engineeringethics (EE)Make the engineers understood that ethical responsibility
should be a central concern of engineering profession and
practices.
Teaching EE can increase student knowledge of relevant
standards.
Knowledge of standards includes more than just knowing
what is written in codes or handbooks.
Danger of partial knowledge on codes of ethics
Teaching EE helps students to improve their ethical
judgments
Teaching EE can accelerate the students ethical will-
power.
7/22/2019 Professional Ethics (Lecture-1).ppt
22/31
How should it be taught?
By using case studiesBy adopting different modes of ethical analysis
-- Drawing the line (Gift giving and bribery)
--Conflict of interest (obligation towards employee & public
safety and welfare)--Trade secrets and Industrial Espionage
By analyzing different concepts those found recursively in
EE.
When should it be taught?
Before earning a particular degree
Before granting license to an engineer
Etc..

The Challenger Disaster
January 27, 1986 (the day before the space shuttleexplosion)
Robert Lund: Vice-president of Engineering at Morton
Thiokol
Jerald Mason (Boss of Robert Lund)Jerald Mason communicated tospace centre
Expecting the postponementthe space centers safety
record was good
Good: needs the approval of all technical people
Lund did not agree for its launch
7/22/2019 Professional Ethics (Lecture-1).ppt
24/31
The reasons for its denialThe temperature at the launch site was freezingThe ice was forming on the boosters
The worryO-Rings sealing on the booster segments
O-rings were not perfect.
The technical explanation says, at a certain temperature,the rings could lose so much resiliency that one could fail
to seal properly. If a ring failed in flight the shuttle could
explode.
07 astronauts at stake
Lund was surprised- notice for the launch of shuttle
The committee did not say anything to Lund, and why
should they?
7/22/2019 Professional Ethics (Lecture-1).ppt
25/31
Continue..
It was understood that- president will take the credit,earned name and fame through media, good publicity, etc.
The ethical dilemma was the space center wanted to
launch the shuttle but they need engineers approval.
Joseph Kilminster (Vice-PRESIDENT) requested JeraldMason to reconsider his decision (agreed later)
Mason--- Lund to reexamine the issue. It is so because
the vice president is ready to sign besides he needs the
Lunds approval.
Think like a manager rather than an engineer
Lund changed his mind and signed the document.
In the next day the shuttle was exploded during the lift-off
time and 07 astronauts killed.
7/22/2019 Professional Ethics (Lecture-1).ppt
26/31
Moral Questions
Should Lund have reserved his decision and approvedthe launch?
Should it be rational for an engineer to think like a
manager when public is at stake?
Manager vs. EngineerM: trained to handle people
E: trained to handle things
Lund was advised to focus on people rather than things
How best to handle his boss, the space center, and hisown engineers?
He was to act much as he would have acted had he
never earned a degree in engineering.

27/31
Why do we obey theprofessional code?
Oath, Vow, Pledge, etc.
Quasi-contract (against violation, there will be legal
action)
It is an obligation for a professional to abide the codes of
professional ethics while doing the professional tasks.
Interpreting the code of ethics
Does public include the 07 astronauts?
Some case studies for you to reflect upon them.

Real World Problems
Infants Under Pressure (Sam Wilson & MedTechcompany)
Using Other Peoples Software (Jim Warren &
NewSoft company)
Not Lighting Up (Will Morgan & a state university
of USA)
Air Bags (Bob Baines & an automobile company)
Flight is also Risky (Ralph Sims & SuperComcompany)

For next class.
Can one be made rational by having just a few
information about his/her professional code of
ethics?
Can one be considered as moral being by virtueof his/her mere understanding of good and bad
actions?
