12.05.2022Crucial part of course is to identify waste. Are we mainly talking about time factor and stuff/inventory not in the right place? What are other waste? I work in IT, and always try to find best practice or procedures after testing the process over time. This concept can be applied anything which is great.

11.05.2022What about if both employees folded the entire airplane by themselves? It would eliminate the transfer time between work cells and the idling of the second cell while waiting for the part assembly. Is there only one type of paper airplane ordered and are they all in A4? Not even talking about the differences between the manufacture times between cells if few types of the planes require different more or less intricate folding patterns! The folding process also doesn't seem all that optimized but I'll let that slide as this is just a demonstration.
As far as I can see after quite a significant time of research into it, one piece flow is an exellent option for departments that manufacture a specific device or appliance but when said department is working in a niche market, manufacturing specialized unique devices in small batches there is no way that one piece flow will work. There is too much variation in the processing times of the said units depending on the size and complexity of the devices we manufacture that the production line grinds to a halt every time waiting for diferent cells to slowly dribble the units up the manufacture chain.. Yet the bosses praise the religion of the one piece flow. It sure works but also has some definite exeptions which should be brought up more instead of making it be the miracle solve-it-all that it theoretically seems to be.
I absolutely despise coming to work just to kill time for 8 hours before going back home to try again the next day. Wasted potential at it's finest.

Muchas gracias.

09.05.2022What about having those two guys build planes start to finish, no wasted motion transferring from one dept to another 🤔. Two planes built start to finish by each “dept”. Think cell mfg
Dany Mendez
09.05.2022it's an simple and amazing example to understand one piece flow!!!
Thibaut Dehay
09.05.2022Well comparaison is kind of wrong: you are only considering 1 batch of five making the two employees doing nothing for more than two minutes.
If you consider several batches, you're bottleneck will be on step 2 (2:45 minutes). So it takes you 2:45 minutes to make 5 pieces (not 4:59). Improvement is still 35%, which is great
axeu
09.05.2022Very interesting video !
But if there is only 1 batch to produce, this video is ok but in real production, when department 1 is producing batch N, department 2 is not waiting but finishing to produce batch N-1.
Then when dept 2 is finishing batch N, dept 1 is starting ton produce batch N+1.
That would be interesting to explain that for batch production : they finish 2 batches within 4min59, batch N-1 then batch N (so 29,9 sec/pcs),
then with one piece flow : they finish 1 + 5 pieces within 1min47 (so 17,8sec/pcs).
So -41% process time / pcs
Lean is the way o/

09.05.2022amazing
thanks

09.05.2022This video does not prove that the batch processing is slower (which, in fact, is faster). It only proves that badly organized process is slower and wasteful.

08.05.2022One piece😁
John Smith
08.05.2022One peeve I have with this type of example (here and other places I've seen similar ones) is that most of the improvement comes from making station 2 work at the time as station 1 as opposed to sitting around waiting. In real life, you're probably going to be continuously doing batches of 5, in which case (after the very first batch) both stations are already going to be working simultaneously. In that case, there can be benefit to one piece flow, but not necessarily… you have to take into account set up time and the like.
Erik Kaare Andersen
08.05.2022This video – and many similar – aims to illustrate the 'large' benefits of reducing batch sizes. It primarily illustrates is the effect of idling resources; resources in the batch process are idle half 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 cycle time. And then we are back to the discussion of the trade-off between transaction costs and holding costs – or efficiency versus speed
Huy Vuong
08.05.2022Stack the 5 pieces of paper and do the folds all at once with just one person. Quality may be worst. Break up into small groups of paper for improved quality, like 2 pieces
BrianP
07.05.2022Don't you have 5x the transportation with the one piece flow? How does that figure in?

07.05.2022In this example, you can eliminate the idle time of the workers entirely by letting both of them do the entire process separately from one another. Also, it looks like you could do the first three folds with the entire batch of 5 stacked on top of one another. One more thing worth considering is that you can do folds 2 and 3 simultaneously with your left and right hand. Perhaps a "press" of some sort would also help speed up the process of carving out the lines in the paper, much like Japanese printmakers do, albeit in a different way, with special wooden tools. Interesting example!

07.05.2022Would there also be an improvement if the 1st and 2nd department make 2 each at the same time(4) and the the remaining (1) by either or?

07.05.2022all of a sadden you see that you need to transport it 5 times.
