Tracking a production schedule against shipment commitments

Track factory milestones against the date the goods must actually be ready to ship, including inspection and recovery time.

Track the supplier’s forecast to ship-ready, not just factory completion. Compare the agreed ship-ready date with the latest forecast for each remaining milestone, and check reported completions against evidence: a factory finish alone does not confirm inspection, rework, packing, document checks and carrier handover are complete.

Work backwards from the commitment

Record the agreed ship-ready date and the date goods are needed at the next handover point. Work backwards through the remaining production, inspection, correction, packing, document-check and carrier-handover steps, keeping the baseline and latest supplier forecast for each. Use the time allowed for unfinished steps; a factory completion forecast is not a ship-ready forecast.

For each remaining step, calculate its latest finish date by working back from the agreed ship-ready date and allowing time for the steps that follow. Compare the supplier’s forecast with that date: the gap is the remaining slack. A forecast that reaches the latest finish leaves no slack; one that passes it threatens the shipment commitment.

For a hypothetical order of three variants, one finished variant does not establish that the full order can ship if the other two still await a shared component. Record remaining units and the critical input by variant rather than relying on average progress.

Escalate the date that matters

At each supplier update, ask which remaining task controls the ship-ready date and request its forecast and completion evidence. Recalculate the slack against the baseline; a forecast that moves towards its latest finish is using the available margin, and one beyond that date is a threat to the commitment.

Tell the commercial or customer-facing team when the forecast threatens the commitment, before it becomes a missed promise. Set the next check around the next date-critical milestone and bring it forward if the forecast moves.

Keep the original agreed date visible for variance review. A revised date becomes an approved commitment only through the agreed change process; record whether the shipment plan or commitment needs revision through that process, including the delivery impact.

Escalation Process for Threatened Ship-Ready Dates

  1. Identify date-controlling taskReview supplier forecast; determine which milestone controls ship-ready date
  2. Request forecast and evidenceAsk supplier for updated forecast and supporting documentation (e.g. inspection report, carrier receipt)
  3. Recalculate slack against baselineCompare forecast finish date to latest allowed finish date based on agreed ship-ready date
  4. Escalate if forecast threatens commitmentNotify commercial or customer-facing team before deadline is at risk
  5. Set next review dateSchedule next check around next critical milestone; bring forward if forecast worsens
  6. Record change request if neededIf revised date is required, initiate formal contract variation via ATO-approved procurement process
