Sharing the next few months of component demand can help buyers and suppliers discuss supply plans earlier. However, a spreadsheet containing quantities and dates needs a clear status: is it a forecast, a stocking request or a purchase order?
State the purpose of the document
Identify whether the file supports planning, quotation, delivery discussions or formal ordering. Whether it creates a purchasing commitment or calls for supplier stocking depends on the applicable agreement and explicit confirmation, not simply the filename.
If you are asking for an assessment, specify the response needed, such as quantities that can be evaluated, lead-time ranges and unresolved conditions.
Use complete part numbers and time periods
Each line should identify the manufacturer, full ordering code, quantity, relevant month or week, destination and meaning of the requested date. Mark an undecided suffix as pending engineering confirmation rather than asking a supplier to select a similar device independently.
For example, a plan for 1,000 pieces in each of three months is a phased requirement. Explain whether it represents total consumption or net purchasing demand after deducting usable stock and existing orders. The example does not represent actual inventory or a supply commitment.
Explain assumptions and uncertainty
Identify whether demand comes from confirmed production, a pilot build or a project still awaiting approval. Include confidence and expected decision dates where useful, without describing an estimate as a confirmed order.
If project demand could change substantially, provide a baseline and possible adjustment range with the conditions behind it. Supplier feedback should likewise distinguish confirmed items from those under evaluation or currently unconfirmed.
Describe revisions explicitly
Date and number every revision, highlighting changes in quantities and timing. Retain the previous version so the supplier can identify increases, reductions and postponements. Agree on update frequency and contacts, while communicating major changes before the next routine update when needed.
If the supplier has already acted under an agreed arrangement, check that agreement and the current progress before changing requirements. A revised forecast does not automatically amend an accepted order.
Reconfirm details when placing an order
Before formal purchasing, confirm the exact code, actual quantity, quotation validity, packaging, delivery milestones and other order conditions. Give the order its own reference and connect it to the relevant forecast revision to avoid double counting.
The demand record should show what is still planned, what has been ordered, what has arrived and been released for use, and what remains unresolved. A forecast helps planning; deliveries still require specific confirmation.
When sharing a forecast with WOMAiELEC, provide phased quantities, target dates, complete part numbers and the purpose of the document. These details support a purchasing discussion; pricing, quantities and delivery arrangements remain subject to confirmation for each item.
