# Work Instruction (作业指导书 / SOP)

On a Chinese production line the 作业指导书 (often called SOP or WI) hangs at the station and is what a new operator follows on day one. Many are copied from engineering documents: dense text, no pictures, steps that skip the critical point, and an outdated version. This skill writes one station's instruction so a new operator can do the job correctly and knows why the key points matter.

Write in Simplified Chinese unless asked otherwise. This is for a single shop-floor operation in manufacturing; for an office or business process SOP, use `sop-writer` instead. The instruction must agree with the plant's control plan, PFMEA and customer requirements, and safety content follows the plant's risk assessment (需核实); a qualified engineer approves it before release.

## Required Inputs

Ask for these if not provided, otherwise infer and label the assumption:
- **Station**: product and part number, process step, line, equipment, fixtures and tools
- **How the job is done today**: the steps in order, ideally from watching an experienced operator
- **Quality requirements**: characteristics checked here, specifications, gauges, sampling, from the control plan
- **Safety**: hazards, PPE, lockout or guards
- **Cycle time** and takt, if known
- **Plant format**: the document template and numbering rule, approval roles
- **Readers**: new operators, literacy level, whether pictures carry most of the instruction

## Output Structure

### 1. 表头
| 文件编号 | 版本 | 生效日期 | 产品/料号 | 工序 | 工位 | 标准工时 | 编制 | 审核 | 批准 |

### 2. 物料与工装
| 名称 | 规格/料号 | 数量 | 位置 |
Materials, tools, fixtures, gauges and consumables, with where they are kept at the station.

### 3. 作业步骤
| 步骤 | 作业内容 | 要点 | 要点理由 | 图示 |
- **作业内容**: one action per step, starting with a verb (取, 放, 对准, 拧紧, 目检)
- **要点**: the critical detail (torque, direction, sequence, position)
- **要点理由**: why it matters (prevents a leak, an injury, a mix-up), so operators understand rather than memorise
- **图示**: a placeholder describing the photo or diagram to take (for example 照片：正确方向，箭头朝上) and marking right and wrong

### 4. 质量检查
| 检查项目 | 标准 | 方法/量具 | 频次 | 不合格处理 |
Matching the control plan; what to do with a bad part (red bin, label, tell the team leader).

### 5. 安全注意事项
PPE, hazards at this station, what never to do (reach into a running machine), and the emergency stop location.

### 6. 异常处理
What counts as abnormal (equipment alarm, material mismatch, a defect repeats) and the response: stop, mark, call the team leader, record. A short "停, 呼, 等" rule.

### 7. 修订记录
| 版本 | 日期 | 修改内容 | 修改人 |

## Quality Checks

- [ ] Each step is one action with a verb, in operation order
- [ ] Key points have reasons
- [ ] Quality checks match the control plan, with reaction to a defect
- [ ] Safety and PPE are specific to this station
- [ ] Every step has a photo or diagram placeholder, with right and wrong shown where it helps
- [ ] Header, version and revision record are complete; approval by an engineer is noted

## Anti-Patterns

- **Dense paragraphs.** Operators read the station sheet in seconds; use short steps and pictures.
- **Key points without reasons.** People skip what they do not understand.
- **Copying the engineering spec.** Write what the hands do, in order.
- **Out-of-date versions at the station.** Version control and removing old copies are part of the job.
- **No abnormal-situation rule.** Operators improvise, and defects pass.
