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. Taking a look at caveman she had an idea (energy source) to take the rock (energy source) put it in her hand [process box] raise her arm ( processing energy) strike the nut (energy processed) and cracked the nut { desired output }.

Good morning class! Sorry! I am late, had some things to take care of. The next method we will look at is shotgun. Replacing all the parts in a given section of a system, this goes back to the trial and error, as well as the substation method. It can be effective in some cases, it can save some time, and it all depends on your aim. If you miss then it try, try again and it stop being cost effective. 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.

Good morning class! The next method we are going to look at is symptomatic. What are the symptom, high fever, runny nose, a cough, a trouble light is on, there is smoke, and it’s not working? What are the signs of life, the signs of energy? The bridge is out, road closed, rail road crossing, man eating lunch, children at play, Good morning class, no output? These are communications’ of a problem or trouble. If you were to see someone lying on the ground face down at 9:00 AM.

Good morning class! Just a quick review; we have looked at trial and error, observation, substitution, Signal tracing or tracking, recognizing the problem, and the ball. We have looked at how the cavemen may have done it. I have not gone over these in detail because most of you may have a general understanding of them. If asked I will go over any and all in more detail. Have you given any thought to the ball and what it represents? What about the box? It is like the ball it represents something. Think about the box, what it represents. It is more than a place to keep the ball! We have seen how troubleshooting started. Out of all we have discussed the first and most important is “recognizing the problem” it is the key to solving it. Taking notes learn all you can about the problem, and taking notes. How much of a problem is it, is it life threatening, or something that will fix itself. A bee sting can be life threatening for some but for most it will go away on its own. I believe that most everyone has used these tool at some time or other in our life.

Technology; when man started to build rather than uses what was there to be used. He had a plan; he designed building, tools and problems.  He made drawing and charts, builders notes, he used math to solve problems.  This is another problem, the drawing and charts, builder’s notes are not always available. They would be useful aid in troubleshooting.  One of the oldest and still used today and probably the first tool used is a rock. A man had a problem; he could not open a nut.  So he had a thought an idea, he pick up a rock and put the nut on another rock, and wham! Now he had two rocks a cut and bruised thumb a hammer, knife, and an ax, oh! He ate the nut. Problem solved.  If you think about this, the energy of the thought pasted trough his body, to the rock to the nut, and out of the rock. Because of the cut he found that rocks sharp edge could cut and be used to cut other things. He could use it to cut down a tree. He could make a boat, house and car, well maybe not a car. We have many hand tools in use today that are power by the energy of our thoughts.

Home work assignment: study this technology.  See how energy is used.

Till tomorrow thank you for your time and god bless.

 I hope everybody is back. So let’s get started. Signal tracing or tracking as the cave man would call it. Following the track of their pray could lead them to finding a problem, and create a problem. Let’s say he was tracking a rabbit. The rabbit runs a cross some hard ground and leaves few tracks, the cave man would have to scout around to find the trail. In doing so he may become the pray of a lion. New problem but tracking or signal tracing is a successful way to find dinner for someone or something.  “if you are going to hunt grizzly bear you had better know what one looks like.” Problem solving you need to know or recognize the problem. Just because you hear or see the grass moving does not mean there is a problem. It could just be the wind or it could be a hungry grizzle bear. There are problems that are not problems but are miss understanding of the operator, and or the troubleshooter.  Identifying and gathering as much information as possible about a problem is the first step. Interrogating getting answers to (who, what, when, where, why and how) is the most important first step in troubleshooting. The failing to do this will add time and the likelihood that the problem won’t be solved. What is the evident, when did it happen, where did it happen, why did it happen, what did happen, who did it happen to, how did in happen. Remember this (There is and will always be someone that is faster, better, and more successful then you are, but don’t let this stop you from trying and you are better than some else).  Let’s take another look at the ball. It’s an icon of an energy source. The form can be physical, electrical, nuclear, and chemical, a thought, an idea, and an emotion, anything that can drive the problem. The energy for this course is feed by a thought, an idea that come from my mind, drives my hands to type, through, the key board, to the computer, over the internet, to your computer, and received by your eyes and to your mind. Along the way many form and sources of energy are used.

Homework assignment:  think about the ball and what it represents, think of the sources of energy that are in your daily life, thank of how it is used and what form.

Till next time may god bless you. Thank you for your time.

“A Computer is only a mirror; it only reflect the intelligent operating it! “ (Roy A Durham 1980)

Good morning Class! The statement here I have used in every class I have taught.  I want you to think. The first class I taught was computer programming in basic. I could have just put the word “THINK!!” but it would not have made you think.  Back to the trial and error, one of the key instruments that are used is observation.  The cave men observed the ambush hunters like, lion, tigers, and bears oh my!  And then try to mimic what they observed. They observed how some animals’ fought off an attack, like badger throwing dirt and rocks or an ape with a stick. Parents observe a babies behavior to find that it has a dirty dipper. And in my case mimic, I have a bad gag reflex, so there is more the one mess to clean up, pun intended.   Have you thought about the ball and box? Do you have any ideas?  Another instrument used is substitution:   Auk to Aork, you do it; Trying to put a rope on a tiger. Replacing a component with another can or will not change the outcome.  Even a known good one may not change the problem, because it is not the root cause of the problem. Taking notes is an important instrument, I hope you are, it aides the next trail. So far we have look at the basics of troubleshooting, some of the components, and a wild guess as to the start of problem solving, and we put the ball in a box. Let’s take the ball out of the box and close the box.  It is not a cat however a cat does like to put a ball in a box. Or get in to the box. What do we know about a ball? It is round, it can be thrown. It won’t stay where you put it, unless you put it in a box.  Here it is an icon; it represents a source of energy. Everything needs a source of energy to exist.  Can you think of anything that exists without energy? This whole class is a source of energy. The conservation of energy theory state that matter and energy will form a ball or bubble therefore I use it to represent energy.   

Homework assignment: think about the ball and what it resents, think about energy.
Thank you for your time.Till next time god bless.
