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 Many are copied from engineering documents: dense text, no pictures, steps that skip the critical point, and an outdated version.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
