Given the batch size and the activity times for operations A, B, C, D and E, what is the lead time it would take the batch to be completed if the outputs were passed one at a time between the activities. This is called continuous flow where you start with a batch and end with a batch, but in between the activities pass an output once it is completed to the next down stream one without waiting for the batch to be completed.
