Activity does not necessarily translate into productivity in the high stakes' world of maintenance. You could be spending the whole day fixing breakdowns, yet you are not making any improvements to reliability. In 2026, it is not merely a matter of work to determine the difference between a messy plant and a lucrative business, but rather the data you decide to measure. Using gut feelings and old spread sheets is no longer a tactic; it is a cost burden. To make a penetration, you must have a compass. The guide presents the vital Key Performance Indicators (KPIs) that will make your maintenance team a cost center to a competitive advantage.
Consider your maintenance of a vehicle. Measures are the speedometer and the odometer- they inform the information about what is currently occurring (e.g. we have already finished 5 work orders today). KPIs are the GPS- they inform you whether you are moving towards your destination (e.g., are we achieving our 95% uptime target?).
Maintenance KPIs are measurable figures which reflect the effectiveness of the maintenance team in accomplishing some of the very important business goals. They play three important functions:
Generally, we group these into four primary buckets to get a holistic view of the operation:
Attempting to follow the more complex KPIs by hand through spreadsheets or whiteboard is an error. A current Computerized Maintenance Management System (CMMS) serves as the brain to your operation, and it would automate the process of data collection, data analysis, and you should be able to make decisions instead of entering data to the computer.
A CMMS removes the information silos that exist between paper logbooks, Excel sheets and mental notes. It is an effective one source of truth, where all stakeholders are seeing the same numbers simultaneously.
The accuracy of your KPIs will solely rely on the quality of data taken at the point of origin. Contemporary CMMS systems apply mobile technology and automation to ensure that the data entry process is easy for technicians, significantly enhancing the quality of the data accuracy of the data entry process (garbage in, garbage out).
Gathering statistics is one thing; insight into them is another. CMMS software is the difference between raw figures and a strategic decision by pre-built Business Intelligence (BI) capabilities.
When you attempt to trace it all, you trace none. The following high-impact indicators should be considered to promote true reliability in 2026.
This is your score on reliability. It is the average count of the duration that an asset has been running before it can run again.
MTBF = Total Uptime \ Number of Breakdowns
Why it matters: The higher the MTBF the more your preventive maintenance (PM) function. Modern systems assist in increasing this by enabling dynamic PMs which are activated by the real usage (e.g., run hours) and not by calendar dates only.
This is a measure of maintainability- how many seconds does a machine take to start again after failure?
MTTR = Total Downtime \ Number of Repairs
Why it matters: When there is high MTTR, the most common causes are usually supply chain problems (waiting parts) and training deficiencies. Application software that has root cause analysis capabilities (such as the 5 Whys) can be used to figure out the source of the delay in repair.
The gold standard of manufacturing. It is a percentage that is a combination of Availability, Performance, and Quality.
OEE = Availability* Performance x times x Quality
Target: World-class manufacturing generally aims for 85% or higher.
This compares the amount of scheduled maintenance work against reactive (emergency) work.
Target: You want this to be >80%. If it’s lower, you are in a "firefighting" mode, which is expensive and stressful.
The inverse of PMP. This tracks how much of your time is spent fixing things that just broke unexpectedly.
Goal: Keep this below 10-15%.
Are you doing what you said you would do? This measures if PMs are completed within the scheduled window (e.g., the +/- 3-day rule). Low compliance usually means you are understaffed or scheduling work during peak production times.
Work Order Completion Rate & Backlog
Total maintenance spends (parts + labor + services) divided by the number of units produced. This helps you identify "bad actor" assets that cost more to repair than to replace.
It is important to track the downtime per department or per asset. It is a key performance indicator that will inform you whether a machine is indeed being utilized fully or is lying idle and therefore you can make decisions about whether to acquire new equipment or optimize the available one.
Safety Incidents and Compliance KPIs
Don't copy paste KPIs from a textbook. Look at your business goals:
Start where you are. If your Schedule Compliance is 40%, don't set a target of 90% next month. Set it at 50%, then 60%. Review these numbers monthly with your team to create accountability.
You know what to track. Now, how do you actually do it?
Use the Business Intelligence (BI) capabilities of your management software.
The future is predictive and prescriptive.
The distinction in executing a maintenance department and assuming a reliability approach is that the former requires tracking the correct maintenance of KPIs. When your metrics are centered on measuring such factors as MTBF, OEE, and Schedule Compliance and the presence of a powerful CMMS to streamline the collection of such data, you can get the visibility you require to minimize costs and enhance uptime.
Get paralyzed data overload. Begin with 3-5 important measures, which support your business objectives, master them, and then grow.
