Visual work instructions that operators actually use
Work instructions get used when they are visual and short: one step per page or screen, an image taken from the CAD model or a photo of the real station, the parts and tools for that step, key values such as torque or orientation, and the check the operator must do before moving on. They live at the station and are updated with every engineering change.

Key takeaways
- One step per page: image, parts, tools, key value, check.
- CAD exploded views show what photos cannot.
- Write verbs and numbers, not paragraphs.
- Put instructions at the station, not in an office folder.
- Link each instruction to the drawing revision it reflects.
A 40-page assembly manual in a drawer does not help the operator who needs to know which way the seal goes. Visual work instructions put the answer at the station, one step at a time.
Anatomy of a good step
| Element | Example |
|---|---|
| Image | Exploded view of the cover and four screws |
| Parts | 1× cover 20145, 4× M6×16 ISO 4762 |
| Tools | Torque wrench 5–25 N·m, 5 mm hex bit |
| Key value | Tighten crosswise to 10 N·m |
| Check | Gap even all around; no seal visible |
Writing rules
- Start each line with a verb: place, insert, tighten, check.
- Use numbers instead of adjectives: “10 N·m”, not “tight”.
- Highlight the one thing that most often goes wrong at that step.
- Keep one step per page or screen; split long steps.
Use the CAD you already have
Exploded views, section views and highlighted parts from the 3D model show orientation and hidden features better than photos. Photos of the real station show tools and fixtures. Combine both.
Keep them alive
Every engineering change should update the affected instructions. Put the product revision on every page so the supervisor can see at a glance whether the station is current.
We create visual work instructions from your CAD models and drawings as part of our manufacturing documentation service.
When to outsource this
- New operators take weeks to assemble a product correctly
- Assembly errors repeat on the same steps
When not to
- Very low-volume custom work where every unit is different
FAQ
Paper or tablet?
Both work. Tablets make updates and videos easy; laminated sheets work where screens are impractical. What matters is that the station has the current version.
Should I use photos or CAD images?
Use CAD exploded views for sequence and hidden features, and photos of the real station for orientation and tools.
Who should write them?
Engineering and an experienced operator together. Test the draft with a new operator and fix every place they hesitate.
How do I keep them current?
Tie each instruction to the product revision and update it as part of every engineering change order.
