Good morning class! The ball and the box troubleshooting method. We have talk about the ball, and that it represents energy. Let’s take a look at the box; it represents [a process]. What can it do? A box is a container, it can store stuff, it can be used to transport stuff, and you can put things in to a box and take them out. You can and have put the ball into the box. The box with the lid closed, you cannot see what is in the box.

We have looked at most of the troubleshooting methods.

Good morning class! Failure mode analysis, what makes it fail? In most cases the root cause of failure in most problems is energy loss, and is typically in the form of heat. Understanding how things fail is another key and important factor in troubleshooting. When the caveman cracked the nut he used to much energy, the extra energy went into the nut and the rocks causing the nut and the first rock to split, some of the energy went into the thumb. Note: the caveman was most likely a cavewoman her name was necessity.
