A work instruction describes how to do one task, step by step, so anyone trained for it gets the same result. This template gives you the standard written format: document control, purpose and scope, references, responsibilities, safety, tools, numbered steps with key points and reasons, acceptance criteria, records and revision history.

Example Example Manufacturing Co., a fictional machine shop, hand-deburrs machined aluminum brackets before final inspection. All values are example values from the fictional drawing, not recommendations.
| WI number / revision | WI-FIN-009 / Rev A |
|---|---|
| Title | Hand-deburr machined bracket BRK-410 |
| Owner | Manufacturing engineering |
| Effective date | 2026-10-24 |
| Next review | 2027-10-24 |
| Approved by | Manufacturing engineer and quality engineer (signatures on controlled copy) |
| # | Step | Key point | Reason |
|---|---|---|---|
| 1 | Check the part number and revision on the traveler | Matches the drawing at the bench | Edge requirements differ by revision |
| 2 | Deburr all machined edges with the hand deburring tool | Stroke away from your body, one direction | Back-and-forth strokes roll a new burr |
| 3 | Break the edges of the two mounting holes | Light, even chamfer all the way round | A sharp hole edge cuts the assembler and marks the fastener |
| 4 | Blow off chips at the extraction hood | Inside the hood, away from people | Loose chips scratch mating faces at assembly |
| 5 | Check the edge break with the gauge on two edges per part | Within 0.2–0.5 mm | Proves the edge meets drawing note 3 |
| 6 | Place the part in the inspected tray and sign the traveler | One part at a time, no stacking | Stacked aluminum parts scratch each other |
| Field | What to enter | Example |
|---|---|---|
| WI number and revision | The number on your master document list and the current revision. An auditor should be able to trace it in one step. | Example: WI-FIN-009 Rev A |
| Title | Verb + object + part or area. One task per instruction. | Example: Hand-deburr machined bracket BRK-410 |
| Purpose | One sentence on what the task achieves and why it matters. | |
| Scope | The parts, revisions, areas and people it covers, and anything it does not cover. | |
| References | Drawings, specifications and procedures by number and revision. Reference values instead of retyping them where you can. | |
| Responsibilities | Who performs, who checks and who approves. Use roles, not names. | |
| Safety and PPE | Hazards of this task and the PPE for it. Put each safety callout on the step where the hazard occurs as well. | |
| Step | One action, starting with a verb. If it needs “and”, it is probably two steps. | |
| Key point | What makes the step right: quality, safety or technique. Make it something a trainer can observe. | |
| Reason | Why the key point matters. People follow key points more reliably when they know the consequence. | |
| Acceptance criteria | How the result is checked, with the same limits as the drawing or control plan. | |
| Revision history | Rev, date, what changed and who approved. Describe the change, not just “updated”. |

This is the text-first controlled format with purpose, scope, references and records. The visual template is a photo-led station sheet for one task. Many teams keep this as the master and post a visual version at the station.
An SOP describes a process across roles: who does what and when. A work instruction describes how one task is done, step by step.
Long enough for one task and no longer. If it runs past a couple of pages, split it into separate tasks.
Use it as a model for the level of detail. Every value in it is an example value from a fictional drawing; replace them with your own.
