Understanding Total Effective Equipment Performance (TEEP) to Optimize Asset Performance
Share this page:
Total Effective Equipment Performance (TEEP) provides a holistic view of how well equipment performs in terms of availability, performance, and quality, enabling organizations to identify areas for improvement and maximize productivity. TEEP plays an important role in driving success in the manufacturing and production industries. By evaluating the overall equipment effectiveness, TEEP enables businesses to make informed decisions, enhance operational efficiency, and boost profitability. This article explains what TEEP is, how it relates to Overall Equipment Effectiveness (OEE), why it’s important, and best practices for implementing TEEP at manufacturing businesses.
What is Total Effective Equipment Performance (TEEP)?
Total Effective Equipment Performance (TEEP) is a metric used in manufacturing and production industries to assess the overall efficiency and effectiveness of equipment utilization. It provides insights into the performance of equipment in terms of availability, performance, and quality, allowing organizations to identify areas for improvement and optimize productivity.
TEEP takes into account the three key components:
- Availability: This measures the actual operating time of equipment compared to the planned production time. It considers both planned and unplanned downtime, including maintenance, changeovers, and other factors that may impact equipment availability.
- Performance: This component evaluates the actual production output of the equipment in relation to its maximum potential output. It takes into consideration factors such as speed, cycle time, and efficiency to determine how well the equipment performs in delivering its intended production rate.
- Quality: TEEP also considers the quality of the produced goods. It measures the ratio of good products to the total number of products produced, taking into account any defects, rework, or scrap that may occur during the production process.
Combined, these three components provide a comprehensive assessment of equipment performance, enabling organizations to understand the overall effectiveness of their equipment utilization. It helps identify areas of improvement, optimize processes, and make data-driven decisions to increase operational efficiency and lower costs. TEEP is also a valuable tool for monitoring and benchmarking equipment performance over time, enabling organizations to set performance goals, track progress, and implement continuous improvement initiatives.
By striving for higher TEEP levels, businesses can maximize production output, reduce downtime, improve product quality, and ultimately achieve operational excellence in their manufacturing and production processes.
Understanding TEEP in Relation to OEE
TEEP and OEE, (Overall Equipment Effectiveness), are two related metrics used to evaluate and measure equipment performance in manufacturing and production processes.
OEE measures the effectiveness of equipment in relation to planned production. It focuses on three key factors: availability, performance, and quality. OEE is a subset of TEEP and provides a narrower perspective on equipment performance.
Similarities between TEEP and OEE
- Focus on performance evaluation: Both TEEP and OEE are used to assess the performance of equipment in manufacturing and production processes. They provide valuable insights into how effectively equipment is being utilized and where improvements can be made.
- Calculation based on three factors: Both TEEP and OEE take into account the three key components; availability, performance, and quality. These factors provide a comprehensive understanding of equipment performance and identify areas that can be optimized.
- Utilize similar performance indicators: TEEP and OEE both utilize performance indicators to measure and quantify the various components. These indicators include metrics such as planned production time, actual operating time, production output, and product quality.
Differences between TEEP and OEE
While TEEP and OEE are similar, there are notable differences between the two metrics:
- Consideration of losses: TEEP considers all types of losses that can affect equipment performance, including availability, performance, and quality losses. It provides a more comprehensive view of equipment effectiveness by encompassing all aspects of losses.
In contrast, OEE focuses specifically on availability, performance, and quality losses. It excludes certain losses due to planned downtime, such as scheduled maintenance or changeovers, and focuses primarily on unplanned downtime as a measure of availability loss.
- Inclusion of planned downtime: TEEP includes both planned and unplanned downtime in its calculations. This means that scheduled maintenance, setup time, changeovers, and other planned events that impact equipment availability are considered in the TEEP measurement.
OEE, on the other hand, only includes unplanned downtime as a measure of availability loss. It does not factor in planned downtime, as it focuses on the equipment's ability to meet the planned production schedule.
- Scope of measurement: TEEP is a measure of overall equipment effectiveness, providing a comprehensive evaluation of equipment performance that encompasses all losses and factors affecting efficiency.
In contrast, OEE specifically measures equipment effectiveness in relation to planned production. It focuses on how well equipment performs against the planned production rate and doesn’t provide a broader assessment of overall equipment performance.
While TEEP provides a more comprehensive view, OEE offers a narrower focus on equipment effectiveness in relation to planned production schedules.
How to Calculate TEEP?
The calculation of Total Effective Equipment Performance (TEEP) involves multiplying the three components: availability, performance, and quality.
The formula for TEEP is as follows:
= Availability × Performance × Quality
Each component represents a specific aspect of equipment performance, and when combined, they provide a comprehensive measure of TEEP.
Steps to Calculate TEEP
To calculate TEEP, follow these steps:
1. Calculate Availability
Availability is the ratio of the actual operating time of the equipment to the planned production time. It takes into account both planned and unplanned downtime. To calculate availability, use the following formula:
= (Actual Operating Time / Planned Production Time) × 100
2. Calculate Performance
Performance measures the actual production output of the equipment compared to its maximum potential output. It considers factors such as speed, cycle time, and efficiency. To calculate performance, use the following formula:
= (Actual Production Output / Maximum Potential Output) × 100
3. Calculate Quality
Quality evaluates the ratio of good products produced by the equipment to the total number of products produced. It takes into account any defects, rework, or scrap that may occur during the production process. To calculate quality, use the following formula:
= (Number of Good Products / Total Number of Products) × 100
4. Multiply the three components to get the TEEP percentage
Once you have calculated the availability, performance, and quality percentages, multiply them together to obtain the TEEP percentage. Use the following formula:
= Availability × Performance × Quality
Let's consider a manufacturing company in the automotive industry that produces car components.
The company operates 24 hours a day, 7 days a week.
The planned production time for a week is 168 hours.
The maximum potential output of the equipment is 1,000 components per hour.
Over the course of a week, the company produces a total of 150,000 components.
Out of these, 145,000 are good components, and the remaining 5,000 components are defective or require rework.
1. Calculate Availability
In this scenario, the equipment experienced 10 hours of planned downtime for maintenance purposes during the week.
Therefore, the actual operating time is 168 hours - 10 hours = 158 hours.
= (158 hours / 168 hours) × 100 = 94.05%
2. Calculate Performance
The actual production output of the equipment for the week is 150,000 components.
The maximum potential output per hour is 1,000 components, so the expected production output for the week would be 1,000 components / hour × 168 hours
= 168,000 components.
Performance = (150,000 components / 168,000 components) × 100 = 89.29%
3. Calculate Quality
Out of the 150,000 components produced, 145,000 are good components.
= (145,000 good components / 150,000 total components) × 100
4. Multiply the three components to determine the TEEP percentage
= Availability × Performance × Quality
= (94.05% × 89.29% × 96.67%)
Benefits of Calculating TEEP

Improving TEEP through Loss Identification and Mitigation
In manufacturing processes, losses refer to any events that result in reduced productivity, efficiency, or quality of output. These losses can hinder equipment performance and impact overall production effectiveness. It is essential to identify and minimize losses to optimize Total Effective Equipment Performance (TEEP).
Types of Losses to Consider in TEEP Calculations
To accurately calculate TEEP, it’s important to consider the various types of losses that can occur in manufacturing processes:
- Planned downtime losses: Planned downtime includes scheduled maintenance, equipment setup, changeovers, and other planned events that require equipment to be offline temporarily. Although these events are necessary, they still result in reduced availability and affect TEEP.
- Unplanned downtime losses: Unplanned downtime refers to unexpected events such as equipment breakdowns, power outages, or material shortages. These incidents lead to idle time and can significantly impact availability and TEEP.
- Performance losses: Performance losses occur when equipment operates below its maximum potential, leading to reduced productivity. Factors contributing to performance losses include sub-optimal speed, inefficient equipment setup, minor stoppages, or slowdowns in the production process.
- Quality losses: Quality losses involve producing defective or non-compliant products that do not meet the required standards. These losses include rework, scrap, rejects, or any additional work required to bring products up to the desired quality level.
Importance of Identifying and Addressing Losses to Improve TEEP
Identifying and addressing losses is important for improving TEEP and equipment performance. Here's why it's important:
- Optimizing equipment availability: By identifying and reducing planned and unplanned downtime losses, organizations can increase equipment availability. This means more operating time, fewer interruptions, and improved TEEP.
- Minimizing performance losses: Addressing performance losses helps optimize equipment performance. By identifying and resolving issues such as inefficient setup, minor stoppages, or slowdowns, organizations can increase the equipment's productivity and improve TEEP.
- Improving product quality: Quality losses negatively impact TEEP by decreasing the ratio of good products to the total produced. By focusing on reducing defects, rework, scrap, and rejects, organizations can improve product quality, increase customer satisfaction, and positively influence TEEP.
- Continuous improvement and efficiency gains: By regularly monitoring and addressing losses, organizations can implement targeted improvements. By leveraging data and insights, they can identify recurring issues, develop preventive measures, and drive continuous improvement efforts. This leads to long-term efficiency gains and improved TEEP.
