The engineering concept of managerial ethics is changing. Initially, the ethics policy of the engineers emphasizes the allegiance to the employer despite any legal or ethical breach. By the mid-1900's these norms were revised to include new goals. It is to protect public safety, health and happiness. Even with this new goal, there are many engineering problems, and it shows a new necessity of reevaluating engineering ethics. Before the beginning of 2000, ethics was an essential part of engineering education, with the primary purpose of protecting public safety, health and happiness.
Who is a professional engineer? Is an engineer who got an accredited school engineering degree, a professional engineer registered, licensed, acting in an ethical manner while performing the job as an engineer? Being a professional is morally responsible. What? The most basic and comprehensive professional ethics. What? Regarding risk issues in particular, we will create useful and safe technology products while respecting the autonomy of customers and the public. Moral integrity, moral integrity, is based on moral care, especially based on integrity agreement of personality.
Since the late nineteenth century, the American engineering has established a specialist organization of engineering experts and has issued technical and ethical standards. For example, the latter includes general ethics, and the engineer requires "publish public statements only in an objective and authentic manner". They include special standards, for example, the specification requires that the engineer "be a loyal representative for each employer or customer, and avoid conflicts of interest." (Engineering Technology Certification Committee, 1977, 1 page)
The due diligence criteria are applied to ethical, ethical and professional criteria of engineering practice and an experienced society of engineers is defined for each specific field. These communities are familiar with engineers prior to acquiring licenses and define a set of appropriately designed standards necessary to demonstrate the function. These include National Institute of Technology Ethics (NIEE), Institute of Electrical and Electronic Engineers (IEEE), Association of Automotive Engineers (SAE), and American Society of Mechanical Engineers (AMSE).
