I'm assuming this is a rhetorical question, but I'll respond anyway. All you'd need to figure out the cost/savings would be the ultimate steady state savings in inventory costs that were derived from this policy (if any), and the number of delays that occurred as a direct result of the policy. With that, you can get a high-level estimate of the financial impact of that decision. You didn't provide enough information to run it through my abacus.Hey "Beanman", I got one to run through your abacus:
An announcement was made (at UAL) that all spare parts had to be accounted for. Henceforth any AMT caught with parts in his toolbox would be fired for stealing. So we all put all the hardware, lightbulbs, minitel headsets, 500MPH tape etc, loose into garbage bags and sent them back to stores. I wouldn't be surprized if, to this day, UAL storekeepers at ORD are still sorting through it all. Not to mention all the delays caused by having to order each and every screw, nut, bolt and lightbulbs from stores. The cost of ill-will had to be steep there. All because some beancounter needed something to do.
It's humorous all of the cute little idioms poeple use when talking to person with a financial/accounting background. I don't refer to all mechanics on this site as "grease monkeys" and I don't refer to the flight attendants as "vending machines with arms", because it's disrespectful to belittle someones career choice. It also shows complete ignorance of what someone in that field actually does.
