MTTR (Mean Time to Repair) | Indicator You Should Know

October 2, 2023

Maintenance indicators play a crucial role in facility management, providing valuable insights into the performance of equipment and the overall efficiency of operations. One of the key maintenance indicators that are widely used in facility management is MTTR (Mean Time To Repair). In this article, we will explore the significance of this indicator, understand how it is calculated, and discuss the relationship between other indicators.

Understanding Maintenance Indicators in Facility Management

Facility managers rely on maintenance indicators to monitor and analyze the performance of equipment and identify areas for improvement. These indicators provide valuable data that can help optimize maintenance processes, reduce downtime, and enhance overall productivity.

The Role of Maintenance Indicators

Maintenance indicators serve as a benchmark to measure the efficiency of maintenance activities within a facility. They provide insights into the reliability and availability of equipment, helping facility managers make informed decisions regarding resource allocation and maintenance planning. By tracking maintenance indicators, facility managers can identify bottlenecks, implement preventive measures, and optimize maintenance schedules to ensure uninterrupted operations.

For example, let's consider a manufacturing facility that relies heavily on machinery for production. By monitoring maintenance indicators such as MTBF (Mean Time Between Failures) and MTTR (Mean Time To Repair), facility managers can gain a better understanding of the equipment's reliability and the average time it takes to repair any failures. This information can help them identify critical equipment that frequently breaks down and allocate resources to address the issue promptly.

Types of Maintenance Indicators

There are various types of maintenance indicators that facility managers use to assess the performance of equipment. Common indicators include:

  • MTBF (Mean Time Between Failures), 
  • MTTR (Mean Time To Repair), 
  • OEE (Overall Equipment Effectiveness), 
  • PM (Preventive Maintenance) compliance. 

What Does MTTR (Mean Time To Repair) Mean

MTTR is a critical maintenance indicator that measures the average time it takes to repair a piece of equipment or restore it to full functionality after a breakdown. This indicator is crucial for facility managers as it helps them understand how quickly they can get the equipment back up and running. By reducing MTTR, facility managers can minimize downtime and ensure that the production process remains uninterrupted.

Calculating MTTR

To calculate MTTR, divide the total unplanned maintenance time spent on an asset (in hours) by the number of repairs performed during a specific period. For example, if a facility experiences a total downtime of 100 hours due to equipment failures and performs 20 repairs during that time, the MTTR would be 5 hours (100 hours / 20 repairs).

It is important to note that MTTR should be calculated using consistent and accurate data. Software for asset management and facility management can be helpful in this case. Facility managers should ensure that all equipment failures and repairs are properly recorded to obtain reliable MTTR measurements. By maintaining a comprehensive maintenance log, they can track the progress of MTTR over time and make informed decisions to improve maintenance processes.

Importance of MTTR in Facility Management

A low MTTR indicates that equipment failures are resolved quickly, minimizing downtime and reducing the impact on operations. By tracking MTTR, facility managers can identify trends, analyze the effectiveness of repair strategies, and take proactive measures to improve maintenance efficiency.

Facility managers can use the MTTR metric to set performance goals for the maintenance team. By establishing a target MTTR, they can motivate the team to work towards reducing repair times and increasing equipment uptime.

Furthermore, a low MTTR can have a positive impact on customer satisfaction. When equipment failures are addressed swiftly, it ensures that products or services are delivered on time, meeting customer expectations and maintaining a good reputation for the facility.

Final Thoughts

In conclusion, maintenance indicators are invaluable tools in facility management, providing insights into equipment performance and efficiency. By understanding how these indicators are calculated, facility managers can focus on reducing MTTR to optimize maintenance processes, minimize downtime, and enhance overall operational efficiency.
