A visual work instruction shows one task at one workstation as a short sequence of photos or sketches, each paired with a single action, the key point that makes it right, and the reason the key point matters. Use this template when an operator needs to do the job correctly from the page alone, without reading a procedure.

Example Example Manufacturing Co., a fictional manufacturer, assembles a sheet-metal cover onto an electrical enclosure at a bench station. All values are illustrative and come from the Example drawing, not from any standard.
| WI number / revision | WI-ASM-014 / Rev B |
|---|---|
| Task | Fit and fasten enclosure cover |
| Part / assembly | ENC-200 cover assembly, drawing rev C |
| Workstation | Bench 3 |
| Takes about | 3 minutes per unit |
| Approved by | Process engineer and quality engineer (signatures on controlled copy) |
| # | Photo shows | Action | Key point | Reason |
|---|---|---|---|---|
| 1 | Cover and gasket on fixture | Seat gasket in the cover groove | Gasket fully in groove all the way round, no twists | A twisted gasket breaks the seal |
| 2 | Cover aligned on enclosure | Place cover on enclosure | Hinge side to the left; locating pins in both holes | Pins set the hole alignment for the screws |
| 3 | Screw pattern with numbers | Run in 4 screws by hand | Start all 4 before tightening any | Prevents cross-threading and a cocked cover |
| 4 | Driver on screw 1 | Tighten in the order 1-3-2-4 | Diagonal order; driver clutches out at set torque | Even clamp load on the gasket |
| 5 | Paint mark on each screw head | Mark each tightened screw | One dot per screw after the clutch clicks | Shows at a glance that every screw was torqued |
| Field | What to enter |
|---|---|
| WI number and revision | The controlled document number and current revision letter. Match the number used in your document control list so auditors can trace it. |
| Task title | Verb + object, e.g. "Fit and fasten enclosure cover". One task per instruction; split anything longer than about a page of steps. |
| Part / drawing revision | Part number and drawing revision the steps were written against. When the drawing revs, this field tells you which WIs to review. |
| Workstation | Where the task is done. Post the instruction at that station so it is available at the point of use. |
| Safety and PPE | Hazards specific to this task and the PPE required. Use icons the site already uses; keep it to what applies here. |
| Tools and materials | Tools, fixtures, gauges and consumables with IDs. List gauge IDs that are under calibration control. |
| Photo / sketch | One image per step, showing the hands and the part from the operator’s view. Crop tightly and use an arrow or circle on the key detail. |
| Action | One action, starting with a verb. If the step needs "and", it is probably two steps. |
| Key point | What makes the step right: quality, safety or technique. Short and checkable — something a trainer can observe. |
| Reason | Why the key point matters. Operators follow key points more reliably when they know the reason. |
| Acceptance criteria | How the operator knows the result is good. Use the same limits as the drawing or control plan. |
| Revision history | Rev, date, what changed, who approved. Describe the change, not just "updated". |
An SOP describes a process at the level of who does what and when, often across several roles. A visual work instruction zooms into one task at one station and shows how to do it, step by step, with images.
No. ISO 9001 asks for documented information to the extent needed to carry out processes as planned. Visual instructions are one way to meet that; IATF 16949 is more explicit about visual standards at the workstation.
Enough to cover one task and no more. If the sheet runs past one or two pages, split it into separate tasks so each stays usable at the station.
Use whichever shows the key point most clearly. Photos are quick and realistic; sketches or CAD views work better when a photo would be cluttered or the part is hard to light.
Treat the images as part of the controlled document. Change the revision when any photo changes, record what changed, and replace the posted copy.
