Click on the icons on the arrows to see assumptions and injections
C: Keep efficiencies up
D': Not cut batch sizes on non-bottlenecks
In order to Increase sales I must Decrease time to process a batch and to get orders to customers faster and in order to Decrease time to process a batch and to get orders to customers faster I must Cut batch sizes in half on non-bottlenecks. But, in order to Increase sales I must also Keep efficiencies up and in order to Keep efficiencies up I must Not cut batch sizes on non-bottlenecks.
