Order Lead Time Estimator
Rough calendar lead time for an order from stage durations, with fabric and trims procured in parallel.
Lead time
57days
Material critical path
30days
The formula
Lead time = max(fabric, trims) + cutting + sewing + finishing + inspection + buffer.
Worked example
Fabric in-house: 30 days, Trims in-house: 20 days, Cutting: 3 days, Sewing: 12 days, Finishing & packing: 5 days, Final inspection: 2 days, Buffer: 5 days. Result: Lead time = 57 days; Material critical path = 30 days.
Assumptions
- Fabric and trims procured in parallel; production stages sequential.
- A quick estimator, not a TNA; overlapping production needs a real plan.
