  • Medical systems
  • Transportation systems:
    • Cars
    • Aircraft
    • Trains
  • Communications systems
  • Consumer products
ethical areas
Ethical Areas
  • Personal behavior:
    • Acting unethically on technical information
  • Professional behavior:
    • Acting unethically in developing artifacts
personal behavior
Personal Behavior
  • Using software defects to:
    • Break into computer systems
    • Steal funds or other assets
    • Effect denial of service
  • Intentionally installing defects:
    • That facilitate unethical acts, e.g. trapdoors
    • That act if prescribed circumstances arise, e.g., if your name is not in the payroll file
  • Clearly all illegal
professional behavior
Professional Behavior
  • What are your responsibilities as a professional?
  • Two areas:
    • Personal acts
    • Advising others
  • Your acts are reflected in the artifacts that you create
  • Your advice is followed by others
  • Unethical behavior in these areas is not illegal
consequences of failure
Consequences of Failure
  • Injury or loss of life
  • Environmental damage
  • Damage to or loss of equipment
  • Financial loss:
    • Theft
    • Useless or defective mass-produced equipment
    • Loss of production capacity or service
    • Loss of business reputation, customer base
consequences of failure15
Consequences of Failure
  • Direct—device fails and causes injury
  • Indirect—defective support tool leads to device that fails
  • Combinations of losses:
    • Immediate damage to equipment
    • Subsequent loss of service
    • Subsequent loss of business reputation
    • Subsequent law suits
what do we know
What Do We Know?
  • We know a lot but not everything
  • More importantly:

You don’t know everything

  • Nobody does
  • You must learn what you are capable of doing and what you are not capable of doing
  • It is OK to say “I am not qualified to do that”
examples of things you probably don t know
Examples of Things You Probably Don’t Know
  • Distributed transaction data processing
  • Dependable storage (polyphase commit protocols)
  • Testing specialized systems
  • Concurrent systems programming
  • Secure systems development
  • Hard real-time system design
  • Achieving ultra dependability
  • Software safety
advice
Advice
  • Agreeing to:
    • Infeasible schedules
    • Unrealistic requirements
    • Unattainable dependability requirements
  • Using inappropriate technology:
    • Process
    • Tools
    • Assessment
using inappropriate technology
Using Inappropriate Technology
  • Process:
    • Failing to consider and to mitigate development risk
    • Depending on the Waterfall process
    • Failing to use proper configuration management
    • Failing to employ proven techniques such as inspections
  • Tools:
    • Failing to use formal languages where appropriate
    • Failing to use languages with strong type checking
  • Assessment
    • Relying on testing
    • Relying on software reliability models

Software Engineering Code Of Ethics

http://computer.org/certification/ethics.htm

should software engineers be licensed
Write a two-page, single spaced paper, include at least 10 refs

Issues to consider:

What are the rules now for software engineers in the U.S?

What are the rules in other countries?

How are software professional standards monitored & enforced in U.S?

What are the professional consequences of the incidents we looked at?

How does that compare with other engineering disciplines like Mechanical Engineering?

Should things be changed for software engineering? If so:

What approach might be developed for software?

What might a licensing system look like?

How would the licensing system be enforced?

Should Software Engineers Be Licensed?
