My position on JIT exactly.
I don’t care if you take a perfectly running tool that finalized it’s run a week ago. If you reset next run, I guarantee it won’t run again. Don’t matter same press,steel,lube, settings ect. Sometimes ya get lucky. Most times ya don’t. Truly a diemakers nightmare. Couple that with the fact the big 3 refuse to allow additional price quota’s to offset tooling issues and you can understand what goes on behind the scenes.
There have been times that we’ve pondered screwing the policy by making deliberate over runs, treating the parts and providing special warehousing to cover our butts on the next shipment.
“to cover our butts on the next shipment.”
I’m sorry, but this issue just has me fired up.
Just thinking of all the times we’ve worked late hours on problem tooling just to make sure parts were available for shipment next morning. And the many times we couldn’t make them available till the last minute, whereby requiring us to airship them. (it ain’t cheap to airship) But it’s a far cry cheaper than shutting down one of their lines I’ll say !
Jeesh, what a waste in policy. Waste of man hours, downtimes, paper work ect.
I don’t remember exactly when JIT was implimented, sometime about 1991-92 I think. Prior to that warehousing was the normal practice. I think it was also about that time ISO 2000 came into being. (what a Joke) that turned out to be. But that’s another story............
