What is a work order? Meaning, contents, and lifecycle

A work order is the formal instruction to do a specific job: what to make or fix, the materials and people it needs, when it’s due, and where it stands right now. It’s the unit of work a shop actually manages — the thing that moves across the whiteboard, rides the floor as a paper traveler, or (better) updates live on every phone in the bay.

What a work order contains

• An ID — WO-0341, so the job can be referenced without a paragraph
• The job — build 40 brackets; replace the bandsaw blade; repair the returned unit
• Materials — pulled from the BOM for production jobs, or listed directly for repairs
• Who and when — assignee and due date
• Status — queued, in progress, done (plus whatever stages your floor really uses)
• History — every status change, part consumed, and note, with names and timestamps

That last item is what separates a work order system from a work order form: the form records intent; the system records what actually happened.

Work order vs job ticket vs purchase order

A job ticket (or traveler) is the paper version that rides with the job — same idea, weaker memory, famous for dying behind workbenches. A purchase order points the other direction: it’s an instruction to a vendor to sell you something. A work order consumes materials; a purchase order replenishes them. In a connected system the two meet automatically — releasing a work order that’s short on plate drafts the PO for the difference.

The lifecycle

1. Created — from a quote, a schedule, or a maintenance trigger
2. Released — materials reserve against stock; shortages surface now, not mid-build
3. In progress — the floor updates status from the machine; everyone sees the same board
4. Done — consumption, time, and photos logged to history
5. Closed — the job becomes queryable evidence: what it took, how long, what it cost

Production and maintenance, one queue

Shops often run production work orders in one tool and maintenance tickets in another — which means “fix the bandsaw” and “build 40 brackets” compete for the same Tuesday without ever meeting. Small shops do better with one board for both; a repair is just a job whose product is a working machine. (Preventive schedules can generate those jobs automatically — see what is preventive maintenance.)

Paper, spreadsheet, or software?

Paper works until a traveler goes missing; a spreadsheet works until the floor stops walking to the computer. The tell for graduating is always the same: status questions get answered by shouting. When “where’s the bracket run?” requires a walk or a holler, the whiteboard has been outgrown.

The one-sentence version: a work order is a job with an ID, materials, a due date, and a memory — and the memory is the valuable part.
