Mary Kate is an intern with a minor league baseball team. She says, I report to two managers: the director of marketing and the director of community relations. From time to time, the director of marketing will ask me to do something, and the director of community relations will ask me to do something, both at the same time. I am not always sure which request I should prioritize. I just want to do a good job for everyone. Considering this scenario, what organizational principle is of concern in this situation?
