BOM: Lead time

Item A BOM 1 week Item B
  • Total duration from process start to output item availability
  • Drives backward scheduling — when o9 must start production
  • Typically expressed in hours or days depending on the process
  • Can include queue time, setup time, and run time components
  • Longer lead times require earlier supply signals to avoid stockouts

BOM Lead Time is the total duration of a transformation process — the time from when production starts to when the output item is available for use or shipment. The planning engine uses lead time to offset supply signals backwards from a due date: if a product is needed on day 10 and takes 3 days to make, production must start on day 7. Accurate lead times are critical for generating feasible plans that don't promise what can't be delivered.
