How would the PM choose the right ethical model for decision making

Hi Sergio,Aboalfazl, Kiron, and Sante,
Thanks for all your inputs I know what Ethics but the question is { What Is a "Right" Behaviour? } As we know Ethics are moral principles that guide human behaviours and are often based on society's cultural values, norms, customs, and beliefs which means that different cultures and even individuals within the same society have widely varying standards many adopt one of following postures in dealing with ambiguous situations like A.Universalist approach, B. Situational approach. C. Subjectivist approach but I wanted you to explore more on the six stages of Kohlberg which may or may not form invariant & universal sequence in individual development. Ethics became a big cultural force causing great demand for companies to use it while conducting business, Many Canadian firms instituting a code of ethics or code of conduct for their employees after so many cases of unethical and fraudulent by top management involved in for example creative accounting, insider trading securities fraud, bribery & kickbacks etc.

I earned a PH D at Cargnegie Mellon University, USA. Because of that I have to study a lot of philosophy Is not my field of expertisse but I still research about that because is closely related to systems (my PH D is on that) and physic which is my other field of research. If you want to know about ethics then you have to go to the basement. Forget about the models you are talking about, it has no sense. On the other side, there is not something like "situational" or something like that. When you read about the basement and understand it you will understand why I wrote it. But it will demand lot of time and it will not solve your situation. To solve your situation is simple: the code of ethics of your actual work place is the first to follow. If there is not a code of ethics in place then you have to follow the country laws (the organization´s code of ethics must not beak them). To assure that country laws are following you must take advice from your organization´s legal department. You must engage them into your projects. If you do not agree with than then you must leave the actual work place. If you can not do that then you have to take advice from an external lawyer just in case your perception is you can not be confident in your organization´s laws department. On the other side, is not right to say that PMI is doing a great effort. The code of ethics of the PMI is for addressing a need to make its certifications recognized by USA certifications boards. If PMI wants to make a real effort then the code of ethics must be legally actionable and each of us that earn a certification must answer each time we broken it like in other fields as medicine for example.
