A toothpaste factory had a problem: they sometimes shipped empty boxes, without the tube inside. This was due to the way the production line was set up, and people with experience in designing production lines will tell you how difficult it is to have everything happen with timings so precise that every single unit coming out of it is perfect 100% of the time. Small variations in the environment (which can't be controlled in a cost-effective fashion) mean you must have quality assurance checks smartly distributed across the line so that customers all the way down to the supermarket don't get mad and buy another brand instead.From my email.
Understanding how important that was, the CEO of the toothpaste factory got the top people in the company together and they decided to start a new project, in which they would hire an external engineering company to solve their empty boxes problem, as their engineering department was already too stretched to take on any extra effort.
The project followed the usual process: budget and project sponsor allocated, RFP, third-parties selected, and six months (and $8 million) later they had a fantastic solution - on time, on budget, high quality and everyone in the project had a great time. They solved the problem by using high-tech precision scales that would sound a bell and flash lights whenever a toothpaste box would weigh less than it should. The line would stop, and someone had to walk over and yank the defective box out of it, pressing another button when done to re-start the line.
A while later, the CEO decides to have a look at the ROI of the project: amazing results! No empty boxes ever shipped out of the factory after the scales were put in place. Very few customer complaints and they were gaining market share. "That's some money well spent!" - he says, before looking closely at the other statistics in the report.
It turns out the number of defects picked up by the scales was 0 after three weeks of production use. It should've been picking up at least a dozen a day, so maybe there was something wrong with the report. He filed a bug against it, and after some investigation, the engineers come back saying the report was actually correct. The scales really weren't picking up any defects, because all boxes that got to that point in the conveyor belt were good.
Puzzled, the CEO travels down to the factory, and walks up to the part of the line where the precision scales were installed. A few feet before the scale, there was a $20 desk fan, blowing the empty boxes out of the belt and into a bin.
"Oh, that," says one of the workers -"one of the guys put it there 'cause he was tired of walking over every time the bell rang."

EVEN ENGINEERS get it wrong on occasion:
NO SHIT, SHERLOCK: Payroll tax cut raises worries about Social Security’s future funding. The 'lockbox' is empty; Social Security is in hock to the tune of ... well, big bucks, it's taking in less in taxes than it pays out, the taxpaying population is decreasing relative to the number of retirees, Uncle Sam Obama just cut the tax rate (again), and everything will remain peachy wonderful?
NOT AT WAL MART: light bulb standards will phase in on Jan. 1. I was in my local Wal Mart this morning, and couldn't afford to buy all the 100-watt incandescent bulbs they had on their shelves.
"THE CASE FOR LIMITED GOVERNMENT is becoming increasingly inseparable from the case for religious liberty." Increasingly, I'm seeing the 'social justice' movement as government-powered bigotry agaist the religious and successful.
LIGHTS OUT for the AirBorne Laser (ABL):
[In] February 2010, the ABL engaged and destroyed its first test target — a solid-rocket fueled Terrier Black Brant rocket. This was followed just more than a week later by another shootdown, this time of a liquid-fueled foreign missile target.But
Despite finally shooting down its first target, ABL has cratered under the substantial funding required for its work, cost-prohibitive and improbable employment scenarios and, most recently, pressure on the Pentagon budget resulting from growing national debt.Like many military developments, the technology problems are hard but soluble; the employment problems (getting close enough to fire without being close enough to be fired upon) are harder and sometimes insoluble.
