What order engineering means
Engineered-to-order (ETO) equipment, such as valves, pumps, skids and pressure vessels built to a customer's specification, cannot go straight from a purchase order to the shop floor. Someone has to confirm what was actually ordered, produce the order-specific drawings and datasheets, get them approved, and release a bill of materials. That work is order engineering. Some companies call it contract engineering, project engineering or application engineering after award.
The main tasks, in order
- Review the PO against the quotation, clarifications and deviation list. See how to check a purchase order against your quotation.
- Hold or join the kickoff meeting: confirm scope, documents, inspection and the schedule.
- Set up the vendor document register from the customer's vendor data requirements list (VDRL).
- Produce order-specific datasheets, general arrangement drawings and calculations, and submit them for approval.
- Prepare or adapt the inspection and test plan (ITP) and test procedures.
- Release the bill of materials and purchase specifications, so buyers order the right materials and certificate types.
- Manage technical queries and change requests from the customer, with cost and schedule impact.
- Hand a clean, approved package to production, and track documents to the final record book.
Who does it
At larger makers there is an order engineering or project engineering team, separate from the proposal team. At smaller makers the project manager often does it, sometimes the same person who wrote the offer. Either way, the handover from sales matters: the person doing order engineering needs the offer, the deviation list and every clarification, not just the PO.
Document approval is the schedule risk
Many orders cannot start manufacture until key documents are approved. Each review cycle adds weeks: you submit, the customer returns a code, you revise and resubmit. Track every document, revision and review code in one register, such as the free vendor document register template, and chase returns that hold up production.
Carrying the bid into the order
Every deviation and clarification agreed in the tender has to show up again: in the datasheets, the drawings, the purchase specifications for materials and the ITP. If the technical deviation list said 3.1 certificates and the customer accepted that, the material purchase order and the record book index should say 3.1 too. If it was not accepted, buyers must order 3.2.
Handling change requests
Customers change specifications after award. Log each change with the clause, the revision, and its cost and schedule impact before you agree to it. Ask for a formal change order for anything that changes price or delivery. Keep the log with the order file: it is your record if delivery slips.
Where OdysseyGPT helps
The Quotation-to-PO Review (beta) compares your quotation, clarifications and deviation register with the PO and its attachments, and cites new obligations, rejected deviations and scope changes. The VDRL/MDR Tracker (beta) turns the customer's document list into a register with due dates, revisions and status, and flags overdue and missing documents. Engineers make every decision. For valve makers, see valve manufacturers.
These tools are in beta
The Quotation-to-PO Review and VDRL/MDR Tracker are in beta. You can request access, and we onboard each team ourselves. Every finding cites the page, sheet or cell it came from, and your engineers decide what to do with it.
