Reduce the stops that repeatedly steal production time.
Downtime reduction focuses on planned and unplanned events that stop production or prevent equipment from running when needed. Effective work combines accurate event data, fault recovery, preventive maintenance, spare parts, changeover improvement, and root-cause action.
Measure the loss before choosing the improvement.
Constraints, idle time, scheduled availability, microstops, speed loss, quality loss, setup, maintenance, and recovery all affect how much useful production the system delivers.
Improve the part of the system that is actually limiting output.
Local efficiency can be misleading. The best improvement target is the recurring loss that changes total production output, lead time, quality, or reliability.
CRIT-ACapture the Event
Downtime needs a consistent start, end, duration, machine state, and reason before recurring losses can be compared reliably.
CRIT-BReduce Recovery Time
Clear alarms, diagnostics, access, spare parts, documented recovery, and trained operators can shorten the time from fault to restart.
CRIT-CEliminate Repeats
Frequent short stops may consume more production than rare large failures, so occurrence frequency matters alongside duration.
CRIT-DSeparate Planned Loss
Maintenance, cleaning, setup, and changeover should be tracked separately so improvement work targets the correct process.
Make constraints and lost time visible.
These diagrams focus on queue growth, productive time, OEE loss layers, downtime events, and recurring loss categories.
Downtime events.
A production timeline makes stop frequency and duration visible, including the short events that operators may otherwise overlook.
Loss concentration.
A simple Pareto view helps teams focus on the few recurring downtime categories consuming the largest share of lost time.
Relevant production and equipment resources.
External references are selected from the approved TempoJS manufacturing link inventory and matched directly to the efficiency topic.
Downtime reduction starts with knowing what stopped, how long it stopped, and why it repeated. Event data, diagnostics, recovery, maintenance, changeovers, spare parts, and root-cause action convert lost time back into production.
