Find a joke about car and computer engineers.

A computer software engineer, a hardware engineer and a department manager went to Switzerland to attend a meeting. Just as they were about to cross a mountain and drive down a steep mountain road, the brakes suddenly failed, the car lost control and rushed out of the guardrail on the side of the road. Incredibly, the car miraculously stopped on the hillside and the passengers on it were safe and sound. But the problem is that they are trapped halfway up the mountain, and the brakes of this car are broken, and the weather is getting worse.

"I know what to do," said the hardware engineer. "I brought a Swiss army knife. I can take the brake system of this car apart, find out the fault, and then fix it, and we can go on the road. "

"No," said the manager, "let's arrange a meeting, first make a suggestion, then make a plan, and then determine the achievable goals. After a series of improvements, we can finally find a solution, and then we can continue our way. "

"Wait a minute," said the software engineer. "Before taking any measures, why don't we push the car back to the top of the mountain and see if the fault happens again?"
