[AT] JIT vs old tractors and long range economics

I have a couple of comments about JIT (Just-in-time delivery of parts and
supplies), both theory and practice. First, JIT while an excellent theory
for maximizing profits has many drawbacks even when implemented as designed.
The most commonly thought of is lack of tolerance for supply interruptions
from ANY unforeseen factor. A more basic flaw is the lack of ability to
build a stockpile for anticipated interruptions such as a maintenance
shutdown at a supplier.
Second, JIT means that there are no stocks of product built for
unexpected spikes in demand. I had firsthand experience with this on the
manufacturing side and was able to quantify the lost sales the company I
worked for experienced as a result. The losses were significant for several
reasons. First, in a competitive marketplace we typically lost those
immediate sales (and spikes in demand sales do not require the usual
discounts to make the deal, hence many times the profit on those sales).
Second, because we did not make those sales, then the accounts who bought
our competition's product were now locked into the competition for at least
part of their future purchases. Think about this as being similar to which
brand of tractor you collect - most people choose based on what they can get
when they are ready and have some cash rather than waiting interninably for
that particular model they MUST collect.
Third, and most obviously tied to antique tractors is that when there is
JIT, then there are no stocks of extra parts left for the repair and
restoration of the product in service beyond the few that were planned for.
This is analogous to the situation where Spencer could not get parts for his
Isuzu even though it was only a few years old....
Fourth, JIT minimizes the income from parts sales for a business.I won't
go into all of the reasons but suffice it to say that again I speak from
personal experience. The interesting part about this is that in any
repairable product business, parts and service typically accounts for
somewhere between a third and two-thirds of the profit stream experienced
over the life of the product! This affects Antique tractors and new farm
machinery significantly. Why new equipment? Because if the parts stocks are
insufficient (usually the case today), then the cost of moving those parts
from place to place rises, the time needed increases unless all is moved by
Next Day Air equivalents, and the amount of time a product can be kept in
service decreases making hte parts business less profitable and reducing
brand loyalty.
Fifth, JIT encourages large companies as suppliers and knocks out small
businesses because of both logistics issues and the inherent bias toward big
that results. This bias is a natural consequence because to survive in a JIT
world, you need to have enough customers and volume to make your product
efficiently where a batch could be done previously and used until nearly
gone, now this is not feasible. This is a gross oversimplification, but
addresses the basic issue of the biases. There are many other aspects of
this bias too, but they all result in the same result and penalize even the
most efficient small business to the benefit of the big ones even though
small businesses make up most of our economy.
Last of the issues I can think of right at this moment is that the
ability of restorers and hobbyists to restore and maintain most old cars,
trucks, tractors etc. is tied to the extra parts left at the end of
manufacture of the products we collect to generate the beginning of the
afterlife (after the end of manufacturing) of those products. This is part
of the reason that restoration of todays cars and tractors will be nearly
impossible in the future.
In short, there is more to JIT than meets the eye as far as its effects
on the economy and us. Now don't get me wrong, I am not saying JIT is
automatically evil, but its negative effects are major and have brought down
many a business. Besides which even in my vegetable farming, JIT only works
as far as there is a stockpile of supplies for when there is that inevitable
weather or labor or equipment emergency..... These are some things to think
about. As a side note about trains, JIT does value speed of delivery over
cost because consistency is the key, but any intelligent variation on JIT
would use a reliable rail system where it could.....
