Value Stream Calculator
Calculate Process Cycle Efficiency (PCE) and total lead time using value stream mapping metrics.
How to Use the Value Stream Calculator
- Enter value-add time in minutes.
- Enter wait, transport, and rework times.
- Click Calculate to see lead time and PCE.
Casos de Uso
- •Lean manufacturing improvement projects.
- •Value stream mapping workshops.
- •Identifying waste in production processes.
Fórmula
Formula: Lead Time = value-add + wait + transport + rework. PCE = value-add time / total lead time × 100%.
Preguntas Frecuentes
What is Process Cycle Efficiency?
PCE measures the ratio of value-adding time to total lead time. World-class lean operations target PCE above 25%.
What counts as value-add time?
Any activity that directly transforms the product in a way the customer is willing to pay for is value-add time.
How can I improve PCE?
Reduce wait, transport, and rework time through kaizen events, 5S, and pull systems to increase PCE.
