The authors discuss that process managers have to manage both the short-term and the long-term. One long-term strategy they suggest is reducing setup cost (time). They suggest that this can improve synchronization by: Group of answer choices reducing cycle inventory and flow time Increase the optimal batch size by reducing he costs to hold inventory Decrease the abnormal variability by increasing the normal variability in the system Eliminate buffers in the system, to identify the variances due to random customer demands and charge appropriately for these services
