Engineering Ethics
Engineering is a profession of public trust. Engineers design the bridges people drive across, the buildings people live in, the aircraft people fly in, and the software that controls medical devices. When engineering fails, people die. Engineering ethics is not an abstract philosophical exercise -- it is the operational framework that prevents harm, guides difficult decisions under pressure, and defines the professional identity of the engineer. This skill covers codes of ethics, case studies of ethical failure, the duty to dissent, and the integration of ethical reasoning into the design process.

The First Canon
The National Society of Professional Engineers (NSPE) Code of Ethics begins:
"Engineers, in the fulfillment of their professional duties, shall hold paramount the safety, health, and welfare of the public."
This is Canon 1, and it overrides all other professional obligations. When safety conflicts with schedule, budget, or management direction, safety wins. This is not aspirational -- it is the defining obligation of the profession.
Codes of Ethics
NSPE Code of Ethics -- Fundamental Canons
- Hold paramount the safety, health, and welfare of the public.
- Perform services only in areas of their competence.
- Issue public statements only in an objective and truthful manner.
- Act for each employer or client as faithful agents or trustees.
- Avoid deceptive acts.
- Conduct themselves honorably, responsibly, ethically, and lawfully.
The Iron Ring (Canada)
Canadian engineers receive an iron ring upon graduation, worn on the working hand's little finger. It symbolizes the engineer's obligation to live by a high standard of professional conduct. The ring is a physical reminder -- every time you pick up a pen or a tool, you see it.
Order of the Engineer (United States)
The American equivalent of the iron ring. Engineers take an oath: "I shall not undertake... any work which I believe will be of harm to the welfare or safety of the public."
Case Study 1 -- Challenger Disaster (1986)
What happened
Space Shuttle Challenger broke apart 73 seconds after launch on January 28, 1986, killing all seven crew members. The failure was caused by O-ring seal erosion in the right solid rocket booster, exacerbated by cold launch-day temperatures (36 degrees F, well below the O-ring qualification range).
