It is important for engineering students to study engineering ethics so that they will be prepared to make (sometimes difficult) ethical decisions during their professional careers. As you read this handbook, you will note that many case studies in engineering ethics do not have a single clear-cut correct answer, but may have many correct solutions, where some solutions are better than others. Therefore, ethical problems can be similar to open-ended engineering design problems, where multiple solutions exist. The purpose of this handbook is to provide students with an introduction to engineering ethics. The goals of this handbook include 1) fostering an increased awareness of ethical behavior, 2) presenting the accepted codes of ethics for professional engineering societies, and 3) presenting engineering case studies that illustrate ethical (or unethical) decisions. It is our hope that this handbook will invigorate and supplement the discussion of ethics in our MAE courses. good
