How to manage engineering material shortages

Start with a specific requirement

Record the job, part or material, quantity, unit, location and required date. Check the specification and approved revision before discussing substitutes. A vague request for 'more steel' is difficult to compare with stock or quote accurately.

Where several jobs need the same item, identify each requirement rather than adding incompatible units or losing the job allocation. Agree the priority of the work before committing limited stock.

Separate the types of supply

On-hand stock is the recorded physical quantity. Some of it may be reserved for another job. Available stock is the portion that can be allocated under your process. Incoming supply may cover a future need, but it is not necessarily in stores and should not be issued as if it were.

Draft requisitions and orders also need careful interpretation. A draft may be included in planning, but it is not proof that a supplier has accepted an order or promised a delivery date. Check the status and intended destination of each line.

Work through a shortage

Suppose a fictional job needs ten bearings. Stores records six on hand, but two are already reserved for a different job. Four may be free to allocate. If no suitable incoming supply covers the balance, six remain to be sourced. This is a simplified example; actual availability depends on all relevant records and allocation rules.

Confirm the stock count, reserve what is genuinely available and review the uncovered quantity. Check whether an existing order or requisition already covers the requirement before preparing another purchase. Then give purchasing the job, part, quantity, destination and date.

Prevent avoidable surprises

Review shortages when a job is created and again as dates, stock or purchasing commitments change. A late engineering change can alter the need; a partial delivery can leave an outstanding balance. Keep those changes visible to both the workshop and buyer.

Agree ownership of catalogue data and stock movements. Record receipt, issue and adjustment promptly, investigate differences through a stocktake, and avoid changing units on established part records without understanding the history.

Keep the decision human

A shortage calculation supports a decision; it does not decide which supplier or substitute is acceptable. Buyers still need to review specification, quantity, charges and delivery information, while managers apply the required approvals.

Recon's development build shows job requirements, reservations and uncovered quantities and supports a reviewed sourcing workflow. RFQ communications remain preview-only.

Prioritise and communicate the exception

Not every uncovered quantity needs the same response. A job due tomorrow may need an immediate review of alternatives, while a later requirement may allow time for several quotations. Record the required date and explain whether it is a firm customer commitment, a workshop planning date or still under discussion.

A storekeeper can confirm physical stock; engineering can check acceptable specifications; purchasing can establish availability and price. Assign an owner for the next action and tell the other teams when the situation changes. If a date is only an estimate, label it as such rather than turning it into a promise.

After a shortage is resolved, check the linked order and receipt. A supplier may deliver a different quantity or split a shipment. Reviewing the balance after each delivery prevents the team assuming that an entire requirement has arrived when only part has been booked in.

What to check before preparing a new order

Begin with the catalogue identity and unit. If the job needs a specific grade or revision, verify that the stock record and any proposed supplier item refer to that requirement. A quantity of the wrong material does not resolve the shortage, even when its description looks similar.

Check the physical location and any protected reservations. Stock in a different bin or reserved for another job may not be available to this requirement. If the count is doubtful, arrange a physical check rather than correcting the number solely to clear a warning.

Review planned supply as well. An approved order, a draft requisition and an unapproved supplier enquiry have different meanings. Check whether incoming quantities are allocated to this job and destination, whether a delivery has already been recorded, and whether a confirmed date is available. Avoid ordering a second time for a need already covered by an appropriate commitment.

Then decide the next action: reserve stock, resolve a record discrepancy, request supplier prices, or escalate a technical change. Record who owns that action and when the job needs another review. After an order or partial receipt, recalculate the position using current information rather than relying on the original estimate.
