Good vs. Bad Design
Good Design Bad Design
Meets all technical
requirements
Meets only some technical
requirements
working after a short time
Meets all cost re uirements Costs more than it should
Requires little or nomaintenance
Requires frequentmaintenance
Is safe Poses a hazard to users
Creates no ethical dilemma Raises ethical questions
