Organizational Ethics

I need an explanation for this Management question to help me study.

1. What do you think about the notion presented by Terris that Lockheed’s ethics program does little to prevent ethical breaches at the highest level of the organization?
2. Are the efforts put forth—such as making sure higher level executives participate in training—enough to help executives navigate what Terris calls the ‘ethical minefield’ faced by leadership in such an organization?
3. What are some things that could be done to address the issue related to ethics at higher executive levels of the organization?
4. Terris points out that the company’s program is overly focused on individuals and that it doesn’t really address group dynamics that can impact ethical situations. For instance, there can be a tendency for groups to ‘go with the flow’ of the group decision making process and overlook ethical issues in the process. What would you recommend that Lockheed Martin do to address this situation?
