At Rogo Industries $($RI$)$ work moves through the factory in large batches that are referred to as work orders. Inspired by the Drum Buffer Rope model discussed in The Goal, 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 scheduler says this is a pull production system. The plant manager insists it is a push system because all the work moves in large batches. Who is right, the scheduler $($pull$)$ or the manager $($push$)?$ Explain your reasoning.

The first word of your answer should be "Scheduler" or "Manager"
