The difference being that apart from the first and last positions on the line (respectively, gathering and throwing water), the tasks are undifferentiated nor is it production, unless of a service.

Yet its goals are the same: to break down a task to it's smallest parts (most happen to be the same in this case) and align the materials and labor so as to minimize waste and maximize speed.

Maybe we need forty bucket brigades and bigger buckets to put out the fire faster, but I'm not convinced task differentiation is intrinsic except where the delivery of service is being performed and it needs to be worded differently to make room for history to "write in" more innovations.
