I have a doubt on Professional responsibility.

I know that if someone is doing anything unethical, we should report to the appropriate body. But what if someone informs me that he is thinking of doing something wrong, what should I do first ?

a) Should I report to PMI

b) Should I report to his/her manager

c) Should I report to my manager

d) Should I first tell him that he/she should not breach the PMI code of conduct.

I believe it should be D. Please correct me if I am wrong.

Note - This is not from any source. But similar to a question from PM Fastrack where I got confused. Unfortunately I did not have any option to see the correct answer.

One more doubt I have is on the cultural difference.

If One person who is from other country doesn't follow a required project process. For example as per his/her country law, he/she cannot come to office during for 10 days when you have urgent requirement.  My primary concern is

should we mould our project laws according to one country's law ?

Should we insist to follow the project rules?

My personal view - We should have taken care of these things during planning and acquiringproject team. And should be clear on ground rules. And everyone should then follow the project rules. am I correct ?

Thanks,

Ashwin
