It’s not enough to just know your stuff. You need to make good choices to be good at your job. Everyone who has the PMP® credential agrees to follow the Project Management Institute Code of Ethics and Professional Conduct, too. The Code helps you with ethical decisions that aren’t really covered in the body of knowledge—and it’s a big part of the PMP® exam. Most of what you need to know is really straightforward, and with a little review, you’ll do well.
You’ll get some questions on the exam that give you situations that you might run into in running your projects and then ask you what to do. Usually, there’s a clear answer to these questions: it’s the one where you stick to your principles. Questions will make the decisions tougher by offering rewards for doing the wrong thing (like money for taking a project shortcut), or they will make the infraction seem really small (like photocopying a copyrighted article out of a magazine). If you stick to the principles in the PMP Code of Professional Conduct regardless of the consequences, you’ll always get the questions right.
In general, there are a few kinds of problems that the code of ethics prepares you to deal with.
Follow all laws and company policies.
Treat everybody fairly and respectfully.
Have respect for the environment and the community ...
