The Drum-Buffer-Rope concept sounds familiar, especially about communication, but I can't recall the exact details on how it connects to the Gateway workcenter.

I practiced a question similar to this, and I feel like operating at peak utilization might lead to more issues rather than solving them.

I think constraints can exist in different forms, but I'm not certain if they always have to be in a factory setting.

I remember something about buffers, but I'm not sure if they should always be after the bottleneck. That seems a bit too absolute.
