Reveal waiting, handling, processing, and setup losses quickly. Compare targets, output, capacity, and operator performance. Turn raw time data into smarter workflow improvement actions.
This layout stays single-column by section, while the form fields use three columns on large screens, two on medium screens, and one on mobile.
| Example Input | Sample Value | Why It Matters |
|---|---|---|
| Available Time | 480 min | Total scheduled operating minutes for one shift. |
| Break Time | 45 min | Removes non-working time from takt analysis. |
| Downtime | 20 min | Shows lost production minutes due to interruptions. |
| Setup Time | 35 min | Highlights changeover and preparation losses. |
| Processing Time | 260 min | Represents value-adding work on the product. |
| Inspection + Move + Queue + Rework | 150 min | Separates support time and delay time from core work. |
| Units Completed | 120 | Used to convert batch times into unit-based metrics. |
| Planned Output | 140 | Needed to calculate takt and achievement rate. |
| Operators | 4 | Supports labor productivity and balance review. |
| Longest Step Time | 1.90 min/unit | Used to assess bottleneck pressure and balance loss. |
Net Available Time = Available Time - Break Time - Downtime
This is the real time window available to meet demand.
Lead Time = Setup + Processing + Inspection + Move + Queue + Rework
Lead time captures the full elapsed time for the batch.
Touch Time = Processing + Inspection + Move + Rework
Cycle Time per Unit = Lead Time / Units Completed
Touch Time per Unit = Touch Time / Units Completed
Takt Time = Net Available Time / Planned Output
Throughput per Hour = Units Completed / (Lead Time / 60)
Capacity per Hour = 60 / Cycle Time per Unit
Process Cycle Efficiency = Processing Time / Lead Time × 100
Delay Ratio = Queue Time / Lead Time × 100
Setup Ratio = Setup Time / Lead Time × 100
Labor Productivity = Units Completed / Operators
Bottleneck Pressure = Longest Step Time / Takt Time × 100
Line Balance Loss = ((Operators × Longest Step) - Touch Time per Unit) / (Operators × Longest Step) × 100
Enter the scheduled minutes for the shift, day, or batch you want to evaluate.
Enter setup, processing, inspection, movement, queue, rework, break, and downtime minutes separately for better visibility.
Input actual completed units, planned output, operator count, and the longest step time per unit.
Click Analyze Process Time. The summary appears under the header and above the form.
Compare cycle time with takt time, review queue risk, and check bottleneck pressure to target improvement actions.
Use the CSV or PDF buttons after calculation to save a structured copy of your inputs and output metrics.
It shows how total elapsed time is distributed across value-adding work, setup, inspection, movement, waiting, and rework. That helps identify waste, bottlenecks, and pace gaps against demand.
Lead time covers the full elapsed time for the analyzed batch. Cycle time per unit converts that total into minutes per finished unit, making it easier to compare output pace with takt.
Takt time shows the maximum time available per unit to satisfy demand. If your cycle time is higher than takt time, the process is likely too slow for the required output rate.
A high delay ratio means too much of the total lead time is spent waiting in queues. That often signals scheduling issues, uneven workloads, batching delays, or limited capacity at a constraint step.
Use the slowest station or operation time per unit. This value helps measure bottleneck pressure and line balance loss, especially when you want to know whether one step controls the whole process pace.
Yes. Replace production units with cases, tickets, documents, or transactions. The same timing structure works for office, service, support, fulfillment, and knowledge-based processes.
Reducing waiting, transport, rework, and unnecessary inspections usually improves process cycle efficiency. Shorter setups and better flow design also increase the share of true value-adding time.
Export results when you want to compare shifts, keep audit records, review improvement projects, or share findings with managers, supervisors, and continuous improvement teams.
