modified JIT

The American media has never understood the Toyota Production System (TPS). Like I mentioned in the last post, by using "JIT" to denote TPS, an image has been created of an ultra efficient factory with 'zero' inventory and all supplies coming in small lots. Inventory is just one of the many wastes in TPS.

One more time an American newspaper is predicting a 'modified' JIT. They had done this about 18 months back when Japan had an earthquake and Riken, Toyota's key piston rings supplier had suffered extensive damages. The article predicts / prophesies that JIT will have to be modified as a lot of suppliers may shut shop. The tone of the article seems like a little kid who has always lost and sees a faint hope of getting back one.

America's automakers have never been able to match up to the Japanese. They tried superficial implementations without much success. All this seems to have hurt their ego a bit too much. The American press has always tried to belittle the Japanese systems and has quite often come up with predictions of the end of TPS. This article is nothing but one more such attempt.

The recession is sure going to force Toyota to change some policies. A few Japanese companies may also close. But, keeping extra inventory definitely does not mean a modification in JIT. JIT is more about an approach of continuous improvement and waste eradication. If the current nature of industry demands higher inventory than keeping it certainly would not go against the tenets of JIT/ TPS.
