And so yes, I can do this from the perspective of the technician. So, this is what they mean in the maintenance program. This is what we want to accomplish, these are the things that should be part of it. Things like what safety is applicable, where to find the...where the risk assessments were done to determine that that was an actual safety issue, what things are mitigated for the safety, techniques as far as how to take measurements on various things or tips on known challenges that I've come across with just understanding how maintenance is done on that.

And this is of course from the perspective of the technician. Now, we also have the ability to turn that from the perspective of the person who writes the maintenance program or even from the perspective of management in general. One of the things that we have like one of our instructor's, his name is Brett Smith, this is what he does. He does lots of classroom restructure and just on maintenance programs.

And so, we can shift this, of course, too to talk about it from that perspective, like how important it is to maintain an asset list, to make sure it's up to date, where draw the line, what's an asset? Are we're going to talk about a single light bulb? Or are we going to be talking about a group of light bulbs as far as our asset or if we're talking about an HVAC system, we're talking about the package unit, the condensing unit, the heating unit is that all one, or that multiple ones. And so, that's kind of how that conversation can go. And then, of course, breaking down the frequency of the maintenance.

And so, all of this is boiling down to conduct...determining what is routine and then, of course, have the idea to formulate and ward your maintenance in a manner that it allows you to detect impending problems. And the challenge with that is, is you don't want it...may have a maintenance warding on your maintenance state to be so broad that the technician doesn't know what you're doing. But at the same time, you don't want to be so narrow towards like place bolt in hole A, place bolt in hole B, that's a little bit too much. And so, the challenge in writing a maintenance program is finding that balance between the two.

And so, predictive maintenance. The idea behind predictive maintenance is it boils down to things like vibration analysis and thermography. Those are the common things that are used for predictive maintenance. How it differs from preventative maintenance is that predictive maintenance is supposed to be non-intrusive. Basically, while the system is operating, you have a way to build and measure how effectively it's working without having to shut it down.

Now, preventive...that does not mean it replaces preventative maintenance, it's just, in general, most preventative maintenance boils down to cleaning, inspecting whatever it is that you want maintenance to be done on. Predictive maintenance is what it sounds like is to see how well that machinery is working and to be able to use noninvasive techniques to build, predict or to trend out when it's going to have a malfunction of any kind.

So then these all boils down to what's called a reliability-centered maintenance, which is a combination of the preventative maintenance of your routine cleaning and inspection. And then, of course, your predictive maintenance where the...your do your vibration analysis thermography, that kind of thing, with the idea of if it ain't broke, don't fix it.

So a good reliability-centered maintenance how it differs from a scheduled routine maintenance is, is that it allows you to use the thermography vibration analysis for you to schedule maintenance when is convenient for you, because it will allow you to predict, this looks like based on a trend over a couple of months that it's going to break again here at two months.

So for like, especially from a production point of view, this is okay, this gives the managers time to, let's Schedule a shutdown so that way that is more convenient rather than wait until something breaks and then you got to shut everything down and now the technicians have to be forced to hurry through it to get it fixed as quickly as possible. And so, the idea like I said, with reliable center maintenance is to allow you to schedule when the maintenance is supposed to happen, specifically making corrective maintenance more be preventative maintenance. So that way there's flexibility with that as far as production management and process management.
