How should we plan preseason blade stock when lead time and minimum order are not yet confirmed?

Build the requirement by approved part number, reconcile usable stock, and ask for an order-specific quantity and schedule proposal. Keep unconfirmed lead times and minimums marked as unknown. You can prepare a useful preseason plan without pretending that a catalogue description or last season’s delivery date is a current commitment.

Count approved parts and usable stock

List the machines expected to operate, the approved parts they need and the serviceable stock already allocated to them. Separate complete ready-to-fit sets from loose sections or incomplete kits. Review previous consumption alongside changes in routes, fleet size and operating hours. If history is weak, write down the demand assumptions and who will check them rather than hiding uncertainty inside a single order total.

Confirm order-specific lead times and minimums

Give the supplier the required arrival location and ready-for-use date, the specification revision and the proposed quantity for each line. Ask which steps remain before production can be scheduled and which event starts the quoted lead time. New tooling or approval work may change the sequence. SENTHAI’s ordering terms describe schedules being confirmed with quotations; use the current written proposal for the exact order rather than assuming a universal number of weeks.

Keep forecast demand, approved purchases and confirmed inbound stock in separate columns. If staged deliveries or supplier-held stock are proposed, clarify who owns the stock, when payment is due and what commitment the arrangement creates before relying on it. Ask whether minimums apply to each profile, grade or complete order. A mixed shipment does not, by itself, establish a shared production minimum or guaranteed availability.

Track readiness gaps and revise the plan

Use a readiness status alongside the quantity. A line can be covered by usable stock, covered by a confirmed inbound order, awaiting a specification decision or awaiting a commercial proposal. Those states carry different risks even when the spreadsheet shows the same number of pieces. Keep unapproved substitutes and parts awaiting identification outside the usable total until the relevant checks have been completed.

Build a preseason readiness list:

• Approved part number and revision, with the machines or routes it supports.
• Usable stock, reserved stock and any incomplete sets shown separately.
• Expected requirement and the operating assumptions behind it.
• Open orders, confirmed quantities and the current arrival estimate for each.
• Required ready-for-use date, allowing for the fleet’s own receiving and fitting work.
• Unresolved minimum, approval or scheduling question, with a person responsible for obtaining the answer.

Review the plan when a meaningful input changes: a route is added, a machine is reassigned, a stock count is corrected or a supplier changes a milestone. Record the reason for the revision so the next buyer can distinguish actual consumption from a planning adjustment. This also makes it easier to discuss a revised quantity with the supplier without implying that an earlier forecast was already a firm order.

Prioritise the unresolved item that could leave a machine without an approved edge. That may be a low-volume special part rather than the biggest purchase line. When a quotation changes, update the affected readiness date and escalate the gap while there is still time to consider approved alternatives. Do not count an unagreed top-up as available stock.

Keep the agreed record with the order and make it available to the people receiving and issuing the parts. When a requirement changes, update the document reference rather than relying on a verbal explanation that the next shift may not receive or be able to verify against the original requirement.
