A software engineer, a hardware engineer and a departmental manager were on their way to a meeting. They were driving down a steep mountain road when suddenly the brakes on their car failed. The car careered almost out of control down the road, bouncing off the crash barriers, until it miraculously grounded to a halt scraping along the mountainside. The car's occupants, shaken but unhurt, now had a problem; they were stuck halfway down the mountain in a car with no brakes. What were they to do?

"I know," said the departmental manager, "Let's have a meeting to propose a vision, formulate a mission statement, define some goals by the process of continuous improvement to find a solution to the critical problems, and be on our way."

"No, no," said the hardware engineer, "That'll take far too long, and besides, that method has never worked before. I've got my army knife with me, and in no time at all I can strip down the car's braking system, isolate the fault, fix it and we can be on our way."

"Well," said the software engineer, "Before we do anything, I think we should push the car back up the road and see if it happens again."
