See where production time goes.
When a line stops, the lost time is only part of the story. Teams also need to know which equipment was involved, what caused the interruption, and what it took to get production running again.
Downtime tracking brings those details into one consistent record. This guide connects the work of capturing events, measuring losses, investigating causes, and improving the way teams prepare and respond.
What is downtime tracking? Downtime tracking is the process of recording and reviewing periods when equipment or a production line is not running, including the duration, reason, and operating context of each stop.
Tracking & Visibility
Build a clear record of every stop.
Start with a consistent picture of what happened on the line. Record the equipment, start and end times, and the reason for each interruption. Give operators a practical way to add context when the machine signal alone cannot explain a stop.
Agree on definitions before comparing lines or shifts. A shared set of reason codes helps the team distinguish a mechanical issue from a material shortage, a changeover, or a stop that still needs investigation.

Metrics & Costs
Understand which losses matter most.
A total number of downtime minutes is a starting point. To make it useful, define the reporting period, separate planned and unplanned stops, and review how those losses affect production.
Use the same definitions across reports. Looking at the duration and frequency of stops together helps you distinguish a long repair from a recurring interruption. Add cost context using the figures that apply to your own line.

Analysis & Improvement
Turn downtime records into useful changes.
Once you can see the losses, review the events behind them. Look for repeat causes, interruptions at the line constraint, short stops, and changeover patterns that deserve further investigation.
Give improvement actions an owner and a review date. Compare the same measures after a change so the team can see whether the problem occurred less often, took less time to resolve, or moved elsewhere.
When the same problem returns, use the approach covered in Root Cause Analysis for Repeat Downtime.

Operations & Prevention
Keep the next shift informed and prepared.
Make downtime information part of everyday work. Share unresolved issues at handover, coordinate maintenance windows, and make the status of required parts visible to the people planning the response.
A useful handover records what happened, what has been done, and what still needs attention. Clear responsibilities and site-approved response procedures help the next shift continue the work with the right context.

Common questions
What should a downtime record include?
A useful starting point includes the equipment or line, start and end times, duration, reason, and relevant operator notes. Keep definitions consistent across the team.
Should planned stops be tracked too?
Record planned and unplanned stops separately. Clear categories let you review scheduled maintenance and changeovers alongside unexpected interruptions without mixing their causes.
