Lead Time Calculator
Sum four nonoverlapping stages and calculate their shares and the processing-time ratio locally.
A QUICK WALKTHROUGH
How to use this tool
- Enter the values below.
- Use one time unit for all stages, each ≥ 0 and total > 0. Total = waiting + processing + moving + inspection. Each share = stage / total × 100. Value-added ratio here means processing / total × 100; classifying all processing as value-added is a user assumption, not a judgment about a real process.
- Calculate and review the result.
