How Total Effective Equipment Performance (TEEP) and CMMS Improve Maintenance Efficiency

When you look at the overall family tree of maintenance management, you have several members branching off. Assets, Inventory, Preventive Maintenance, and Work Orders. Within each of those, you'll find further breakdowns for you to consider.

You also should add one more branch to this tree: Reports. In fact, you could put this in each of your sub-categories of management. You need different reports for each area.

Today, we'll discuss one report called Total Effective Equipment Performance (TEEP). It belongs under the Assets section. It accompanies similar reports, such as overall equipment effectiveness (OEE) and overall operations effectiveness (OOE).

TEEP looks at assets in the sense of total potential availability multiplied by quality multiplied by performance. Let's break down these.

Availability – In this calculation, you need to find the percentage of time by dividing "up-time" by all available time. Which means operating a machine every day, all day, year round.

Quality – The perfection of the produced items.

Performance – The level at which the equipment operates.

Understanding TEEP: How It Measures Equipment Performance

To understand this better, let's look at the human machine. Suppose a person had the ability to work twenty-four hours a day, seven days per week, for an entire month (thirty days). The person never stops for rest, meals, or sleep breaks. Also, the individual produces top-quality products throughout the period.

In this case, you'd easily calculate 100% TEEP. Transfer that same scenario to a particular machine in your plant. Even when you do, you see that not every machine will run continuously for that long. No operation runs that way.

So, let's start with an example of a machine running for 18 hours per day without stopping. This makes the availability percentage 75%.

Delving deeper, let's say the machine operates at 80% of its potential performance.

Finally, the product perfection rate (quality) stands at 92% (quality).

Multiply .75 x .8 x .92. This equals .552 or a TEEP of 55.2%.

Let's bring in one of the other calculations from before: overall equipment effectiveness (OEE). This measurement differs slightly in that it looks at the current level of productivity. For this percentage, you obtain the availability percentage by dividing the actual operational time by the planned operational time.

Supervisors look at OEE for current production. They'll make adjustments to preventive maintenance (PM) activities based on this and other factors.

Now, bring in the other measurement: overall operations effectiveness (OOE). With this, you still multiply performance, quality, and availability. You obtain the last percentage by the same division of actual production by planned, but you take into account unscheduled time for downtime.

So, what importance does TEEP have? Actually, they can work together. Look at it this way:

TEEP = All time.

OOE = All planned and unplanned time.

OEE = Planned production time.

In this sense, TEEP may not provide a lot of relevant information for maintenance personnel. Management may use it when considering the feasibility of increased production time.

Sometimes, supervisors look at TEEP when they feel that the OEE lacks accuracy. Remember, the calculation doesn't take into account maintenance time. This means you may receive a better OEE percentage than what reality shows.

This doesn't mean you should ignore one calculation. Run the numbers or percentages but compare the differences. From these, you gain a better perspective of needed adjustments and improvements. You also make better-informed decisions about adding shifts, personnel, or operational time.

TEEP and CMMS: How They Work Together to Improve Maintenance

A computerized maintenance management system (CMMS) acts like a central command center for all things maintenance, and this has a ripple effect on TEEP. Think of it this way: TEEP is all about maximizing how much your equipment is actually producing good stuff. To do that, you need your equipment to be running (availability), running efficiently (performance), and producing quality products (quality). A CMMS helps with all of those.

For availability, a CMMS helps with organizing planning. It schedules preventive maintenance so you catch problems before they cause a breakdown. You have efficiency with standardized work orders. It even helps manage spare parts so you have what you need on hand, further minimizing downtime.

When it comes to performance, a CMMS tracks how your equipment operates, looking for clues that might indicate a performance dip. By analyzing this data, you can fine-tune maintenance and make sure everything is running at its best. And for quality, a CMMS helps you schedule calibrations and inspections to ensure your equipment stays accurate and produces top-notch products. It also helps track and analyze problems so you can find the root cause of quality issues and fix them for good.

Ultimately, a CMMS gives you the data you need to make smart decisions about maintenance. It helps you continuously improve your processes, reduce costs, and get the most out of your equipment. It's like having a dedicated coach for your equipment, always pushing it to perform at its peak and contribute to a higher TEEP score.

Maximizing Maintenance Success with TEEP and CMMS

Obviously, you improve the three factors to attain TEEP. Be aware that you need to make adjustments where you can with the correct employees.

Availability – Do you want the machine operating for more hours? That means more personnel or extra hours assigned. Performance – How can you keep the machine running to capacity? Adjustments in PMs may help. However, watch over-maintenance. That risks further issues.

Also, work with production people so they don't overuse the machine. Forcing the equipment to do more than design parameters risks further issues and more downtime.

Quality – Of course, PMs can help here, too. You also have to monitor resources. Lower-grade materials risk lower-quality products. Lower-grade materials also increase the chances the machine falters.

For example, what if you filled a Formula One race car with regular gasoline? How well will it run? What damage does the engine suffer? In this scenario, the incorrect "material" (gas) affects both performance and quality.

Discuss TEEP with your maintenance team. Share the information with both production and management personnel. Used in conjunction with other sibling measurements, you stay on top of your asset management.
