What do ethics most closely relate to?

Read the following passage and answer the next 3 question (Q21-Q23) According to Wallace, "A credo generally describes the highest values to which the company aspires to operate. It contains the `thou shalts.' A code of ethics specifies the ethical rules of operation. It's the `thou shalt nots." In the latter 1980s, The Conference Board, a leading business membership organization, found that 76% of corporations surveyed had codes of ethics. Some business ethicists disagree that codes have any value. Usually they explain that too much focus is put on the codes themselves, and that codes themselves are not influential in managing ethics in the workplace. Many ethicists note that it's the developing and continuing dialogue around the code's values that is most important. If an organization is quite large, e.g., includes several large programs or departments, it may want to develop an overall corporate code of ethics and then a separate code to guide each of its programs or departments. Codes should not be developed out of the Human Resource or Legal departments alone, as is too often done. Codes are insufficient if intended only to ensure that policies are legal. All staff must see the ethics program being driven by top management.
