Gifts, meals, services, and entertainment Treatment of confidential or proprietary information Consideration of the employer's assets Outside employment/activities (Moonlighting) Some engineering societies are addressing environmental protection as a stand-alone question of ethics. The field of business ethics often overlaps and informs ethical decision making for engineers. Case studies and key individuals Petroski notes that most engineering failures are much more involved than simple technical mis-calculations and involve the failure of the design process or management culture. However, not all engineering failures involve ethical issues. The infamous collapse of the first Tacoma Narrows Bridge, and the losses of the Mars Polar Lander and Mars Climate Orbiter were technical and design process failures. Nor are all engineering ethics issues necessary engineering failures per se - Northwestern University instructor Sheldon Epstein cited The Holocaust as an example of a breach in engineering ethics despite (and because of) the engineers' creations being successful at carrying out the Nazis' mission of genocide. These episodes of engineering failure include ethical as well as technical issues.
