How to Write Work Instructions Operators Actually Follow
Seven steps to clear, visual instructions, with examples from the shop floor.
Short answer
To write effective work instructions, define the scope and audience, break the task into steps with one action each, add a visual to every step, mark safety and quality checks, test the instruction with a new operator and manage versions centrally.
The 7 steps
- 1Define scope and audience. Who performs the task and at what skill level?
- 2Observe the best performer. Record how the expert actually does the job.
- 3One action per step. Start each step with a verb and keep it short.
- 4Add a visual to every step. A photo or short clip beats a paragraph of text.
- 5Mark checks. Highlight safety warnings and quality checkpoints.
- 6Test with a new operator. If they hesitate, the step is not clear yet.
- 7Control versions. Publish centrally so everyone uses the latest version.
