Yes, it does work well. Like any other technique it has to be used
with intelligence. You can't use a hammer to saw a board. LOL
If you check it is basically a technique called SIS (short interval
scheduling). It was developed after the 2nd world war by Alexander Proudfoot
in Chicago. His consulting house is still there and so far as I know they
still use the technique. In the late 70s I worked for a Proudfoot spinoff.
We used the SIS technique and it worked well excepting the resistance we got
from the superintendent and foreman level. The problem as they see it is
that they have to actually get out and supervise. In addition it makes what
is going on in the shop relatively transparent to top management.
On the other hand, I first learned the technique in 1951 when my
German foreman ran his shop that way. I have no idea where, when or by whom
the technique was invented. I suspect it goes back into the mists of
antiquity.
I also noticed that Ford Motor Company used a system very like SIS on
their production lines with great results.
