To best for a trained psychologist to understand the difference, which is incredibly huge, he should compare how a Project Manager works based on the American Project Manager Institute in opposite to the German Sigma system.
The German is a CEO and the American an Assistant.
"I don't know. I ask and call you back", "Ok.Thanks for telling me. Call the Responsible Mr Jon and talk to him. Let me know if you two can stick to the timeline or if I have to delay the other teams" is as much daily work for an American PM as something a German Manager won't say.
