We know that a process is only as fast as its bottleneck. This means the speed or capacity of a bottleneck in a process really determines the overall output or capacity of the process. Charlie Cooker knows that his extruder is the bottleneck for the cookie shop, so to find the daily capacity of the shop, he simply needs to find the daily capacity of the extruder. The process is a batch process, meaning the product moves from step to step in batches, where batch size is determined by the weight of dough. Each batch must be completed by the extruder before a new batch can be started at the extruder. The time it takes for the extruder to complete one batch (total batch time) is made up of the sum of the setup time (which is non-value added because it does not do anything to transform the dough into a finished product) and the processing time. The setup time in this step is the total of the time taken to load the dough into the machine and to clean all the cutters. The processing time for a batch is the total time to extrude all the cookies in the
