This video - and many similar - aims to illustrate the 'large' benefits of reducing batch sizes. It primarily illustrates is the effect of idling resources; the process steps with the large batches are idle most of the time. In a continuous flow, the throughputs are identical and independent of the batch sizes, i.e. the productivity is identical. The benefits of reducing batch size come from the reduced WIP and/or lead time. And then we are back to the discussion of the trade-off between transaction costs and holding costs - or efficiency versus speed.
At 4:18, you didn't save 18 minutes. the process still takes the same amount of time. The only thing this effects is that from when you start the production process, you get your first item ready to ship at 3 minutes in rather than at 21 minutes in. All this is doing is shifting around how soon something is completed. It has no bearing on the time it takes to produce something.

Correct Erik
Good video. I liked the way you explained.
Thanks
Thanks a lot Ilton
Good simple explanation!
Thanks Danny
Is these product in between 1st station and 2nd station in example of one piece flow are consider as a WIP?

Peter thats good point. :)
Helpful
Thanks a lot
Thanks 😊
is two processes different at lead time for first order of 10 pieces then they equal at lead time of the next order of 10 pieces ???
please answer
In pharmaceutical industry where production batch size is depend on equipment capacity. One piece flow will not work at there.
Yes Saurabh, in some industries this might not work.
Nice
Thanks Nilesh 😎
Yhh
Thanks
