Engineering Ethics

  • Engineering is a profession
  • Similar to law

• Similar to medicine, dentistry and pharmacy

• Hire by clients (and employers)

Interaction Rules

• Engineers rarely work as alone or individuals
• Generally work in teams
• Impact society as a whole(labor, products)
• Therefore, we need a set of interaction rules
• Etiquette( 'vqnJ,ntJ1'n)
• Law(fl1J1tJ)

• Morals (in)

• Ethics (1tlA)

• Etiquette: J1501V1
