Cycle Time Analyser โ Free Time Study Tool for Lean Manufacturing
Lean Manufacturing ยท Cycle Time Analyser
Record time study observations using the stopwatch or manual entry. Statistical analysis removes outliers, calculates mean cycle time, and applies a rating factor and allowances to derive normal time and standard time โ the foundation of capacity planning and takt time comparison.
Observed Time = Mean of readings
โ
Normal Time = OT ร (Rating รท 100)
โ
Standard Time = NT ร (1 + Allowance รท 100)
Standard time is the benchmark used in capacity planning. Compare it directly to your takt time โ if standard time > takt time, the operation is a bottleneck.
