Equipment Servicing and Maintenance: 7 Crucial Metrics to Check

When it comes to equipment maintenance, operations and service managers have their tasks cut out. 

Keeping your equipment running smoothly is critical to ensure optimal performance while sustaining maximum uptime. 

Even a minor equipment failure can lead to significant operational disruption, leading to missed deliverables, frustrated clients, loss of work hours, huge maintenance costs, and the loss of future business. 

Let’s look at some statistics underlining the importance of regular machine maintenance to ensure a prolonged asset lifecycle. 

  • 53% of companies spend up to 30 hours weekly on equipment maintenance programs (Source: Plant Engineering ).
  • 88% of companies implement Preventive Maintenance (Source: Plant Engineering ). 

Without a doubt, equipment maintenance holds the key to optimal resource utilization, but it goes beyond merely scheduling regular equipment servicing and maintenance. 

You must analyze Maintenance Metrics and key performance indicators (KPIs) to understand your equipment performance and make informed business decisions. 

So, what are some key maintenance metrics, and how to monitor them? 

Read on to know more about it. 


Stat Fact: A report from Technavio predicts the digital transformation in the oil and gas industry to reach $68.64 billion in 2028, witnessing a CAGR of 16.73% between 2023 and 2028.

What are Equipment Maintenance Metrics? 

Equipment maintenance metrics are various standards of measurement that are used to mark the progress/decline in the operational performance of your field service equipment, tools, and assets. 

While some metrics provide more qualitative and quantitative insights into equipment performance and maintenance programs, they all combine to enable field service or asset-centric businesses to make informed decisions for overall growth and profitability. 

For example, a preventive equipment service program can give you vital information on the current performance, whether it is above or below expected performance, and the degree of deviation.

7 Key Field Service Equipment Maintenance Metrics 

A comprehensive equipment maintenance strategy can help your business sustain equipment uptime and boost overall operational efficiency while implementing machine and tool maintenance strategies for long-term growth. 

Let’s take a look at some key maintenance metrics that you need to focus on to drive optimal equipment maintenance, performance, and sustainability.

  • Mean Time Between Failures (MTBF)

Mean time between failures is defined as the average time between equipment failures. It is a performance metric that displays the duration when equipment functions without any snags or disruption. 

Higher MTBF indicates the longer operational cycle of your equipment while lower MTBF indicates a shorter functional cycle. 

MTBF Calculation= total operational time/ total number of breakdowns.

Significance: MTBF helps companies analyze the reliability of an asset and control unplanned downtime. 

  • Overall Equipment Effectiveness (OEE) 

Overall equipment effectiveness is an equipment management and maintenance metric that gauges the productivity or output of a particular piece of equipment. 

The metric considers the availability, performance, and quality of equipment to present a data-driven picture of how effective your maintenance operations are. 

OEE Calculation= availability x performance x quality 

Significance: OEE helps companies get clear insights on performance hurdles and how to avoid them. 

  • Mean Time To Repair (MTTR)

Mean time to repair is a performance metric that measures and indicates the average duration of repairs after the equipment has broken down. 

It is like a stopwatch that starts ticking as soon as repair work starts and stops when the repairs are completed and the machine is restored to its working condition.  

Low MTTR indicates the ability of a maintenance team to repair and restore the equipment in time but high MTTR indicates that maintenance processes need to reduce downtime and prevent productivity loss. 

 MTTR Calculation= total repair time/total number of repairs 

Significance: MTTR helps companies identify the root cause of equipment failure and improve the efficiency of maintenance and servicing operations.

  • Planned Maintenance Percentage (PMP)

Planned maintenance percentage is the equipment metric that represents the average time spent on the number of planned maintenance activities as compared to unplanned maintenance activities. 

PMP Calculation= planned maintenance hours/total maintenance hours x 100

Significance: Helps businesses optimize equipment maintenance processes further. 

  • Equipment Downtime

Equipment downtime performance metric is defined as the total number of times a specific piece of equipment remains dysfunctional due to maintenance or breakdowns. Downtime can lead to low productivity and increased costs which are red flags for any asset-centric business. 

Equipment Downtime Calculation= total downtime/ total production time x 100

Significance: ED helps maintenance teams identify the root cause of frequent downtime and take necessary steps to increase uptime and productivity. 

  • Emergency Work Orders (EWOs)

Emergency work orders are classified as “urgent” maintenance tasks that call for an immediate response of repairs & servicing teams to prevent further equipment damage or workplace safety hazards. 

Maintenance teams have to perform equipment repairs quickly and get it running as soon as possible. Higher EWOs indicate poor equipment performance or lack of preventive maintenance while lower EWO represents an efficient machine performance. 

EWO Calculation= total emergency work orders/total work orders 

Significance: EWOs can help identify repetitive equipment performance issues and implement effective maintenance operations.  

  • Preventive Maintenance Compliance (PMC)

Preventive maintenance compliance is a performance metric that calculates the total percentage of preventive maintenance tasks completed on time, as per the defined schedule. 

PMC maintenance metric on the higher side indicates an effective implementation of PM programs by maintenance teams. Low PMC indicates the need for improvement in following and maintaining PM compliance. 

PMC Calculation = number of PM tasks completed on schedule/ total PM tasks X 100

Significance: PMC helps companies analyze the PM programs’ consistency. 

Equipment Maintenance Metrics: Benefits to Businesses

Let’s understand how machine maintenance metrics benefit businesses in the field service or any other industry where equipment and assets have a major role to play in daily operations.  

1. Informed Decision Making

Real-time access to equipment and machine maintenance data enables field service companies to make well-informed decisions about equipment replacement, resource allocation, and machine maintenance strategy. 

For example, if the maintenance cost for a particular machine is increasing over time, the business should identify the root cause and decide whether the asset needs to be repaired or replaced. 

 2. Minimize Maintenance Costs

According to an Add Energy 2022 report, 37.2% of maintenance managers cite budget restraints as a potential challenge over the last 5 years. This statistic shows how keeping a check on field service assets’ maintenance costs is important for businesses today. 

Equipment service and maintenance metrics help companies cut down on unnecessary maintenance costs as they can analyze how to optimize their maintenance operations, resource allocation, and inventory management. 

For example, companies can avoid unnecessary maintenance costs on assets not being deployed in the field by preventing overstocking and understocking of inventory

3. Improve Equipment Longevity

Premature equipment replacements and frequent breakdowns result in the loss of productivity and higher maintenance costs. Timely maintenance of all field assets optimizes their performance and improves their shelf life. 

Equipment longevity due to proper maintenance and servicing programs helps companies save money on frequent inventory stocking while getting the most out of their equipment. 

For example, well-maintained field service machinery can easily stay operational for many years and deliver optimal performance, which reduces the need for premature replacement and higher maintenance costs. 

4. Enhance Safety and Compliance

Proper field service equipment maintenance is crucial to ensure employees’ safety at the workplace and help companies stay compliant with the latest workplace safety standards. 

Citing service and maintenance metrics allows companies to identify potential safety hazards and take corrective steps in time to avoid the occurrence of future accidents. Compliance with regulatory requirements enhances workplace safety and mitigates liability risks. 

For example, tracking metrics like PMP and PMC can help asset-centric companies clear audits and prevent accidents.  

5. Encourages Smooth Communication Across Departments

Seamless, timely communication across various departments is another significant benefit of maintenance metrics. Data sharing across different teams keeps everyone updated on equipment servicing schedules, potential risks, and areas that need improvement. 

Easy access to vital information prevents communication loopholes and misunderstandings among team members and keeps everyone on the same page.
