Where high-volume value streams exist with irregular or indeterminate arrival
or demand patterns (such as health care laboratories often see), the answer is to
look for ways to reduce the batch size to the optimal point so that work can flow
whenever possible. When flow ceases, the work can be managed and controlled
in smaller batches. Smaller batches mean faster turnaround times, which in turn
relates to faster throughput and higher levels of productivity for the organization.
