3. An operation has four work centers A, B, C, and D - with task times of 1, 2, 3, and 4 minutes respectively. Each work center initially has one worker. If a worker is added to work center D (to work on a different unit than the first worker, so that two units are completed every 4 minutes), how will this affect performance when the operation is working at maximum capacity? (Assume new units are started at the same pace as the bottleneck completes units.) (5 points) 1) Average worker capacity utilization will increase and average throughput time will decrease 2) Average worker capacity utilization will decrease and average throughput time will increase 3) Average worker capacity utilization will increase and average throughput time will remain the same 4) Average worker capacity utilization will decrease and average throughput time will decrease 5) Both average worker capacity utilization and average throughput time will stay the same
