At Rogo Industries $($RI$)$ work moves through the factory in large batches that are referred to as work orders. The production scheduler at RI uses the following rules in releasing work orders to the factory floor. Every morning, she checks the number of work orders that were processed the day before at the paint cell, the factory$$s bottleneck. She then schedules that number of work orders to be started for the current day. That is$,$ if five work orders went through the paint cell on Tuesday, five work orders would be started on Wednesday. The production scheduler says this is a pull production system. The plant manager insists it is not a pull system because all the work moves in batches. Who is right? Explain your reasoning.
