At Auschwitz, one thing that stood out to me was the process the Nazi's had to transport and separate  Jews from their home to the concentration camp. As an Indistrial Engineering student, we talk a lot about having processes that flow from one step to the next without adding wasteful time. The tour guide mentioned that they come in on a train and then they get off and sort who should be put in the gas chamber or who is fit for work. Once they decide, those who get gassed go to the gas chamber and those who are fit for work go another direction. They continually do this process with all transports and also collect their luggage. This stood out to me and is the same sort of process Industrial Engineers use today minus the intent the Nazis had.
