Process Type Guidelines

Assembly Operations

Focus

Sequence, torque specs, orientation

Include

Part numbers, installation direction, fastener specifications

Visuals

Assembly diagrams, before/after photos, exploded views

Checks

Fit, alignment, function tests

Machining Operations

Focus

Setup, program, tooling, parameters

Include

Machine settings, feed/speed, tool specifications, fixtures

Visuals

Setup photos, tool paths, measurement points

Checks

Dimensional verification, surface finish, first-piece inspection

Quality/Inspection

Focus

What to inspect, how to measure, accept/reject criteria

Include

Gage R&R references, sampling plans, measurement methods

Visuals

Measurement locations, gage usage, defect examples

Checks

Calibration verification, data recording

Material Handling

Focus

Movement, storage, protection, traceability

Include

Handling methods, storage conditions, labeling, FIFO

Visuals

Packaging methods, storage layouts, label formats

Checks

Condition verification, count accuracy, traceability

Best Practices

Writing Style

Active voice

"Insert the bolt" not "The bolt is inserted"

Present tense

"Check the torque" not "The torque should be checked"

Imperative mood

Direct commands to operator

Concise

One action per step

Specific

Exact values, not ranges when possible Visual Elements Photos of actual parts/processes (preferred) Diagrams for complex assemblies Flowcharts for decision points Callouts for critical features Color coding for emphasis (warnings in red/yellow) Quality Integration Embed quality checks within process steps Reference control plans Link to FMEA high-priority items Include mistake-proofing (poka-yoke) features Document inspection frequency Revision Control Clear document numbering system Revision history table Change bars for modified sections Effective date tracking Training requirements for changes Common Mistakes to Avoid Assuming operator knowledge Missing safety information Vague quantities or specifications No visual aids for complex operations Incomplete tool/equipment lists Missing quality acceptance criteria No revision history Passive voice or unclear instructions Quick Reference: Document Selection Need Document Type Complexity Operator guidance Work Instruction Low-Medium Department procedure SOP Medium Process definition Business Process Medium-High Quality procedure Quality SOP Medium Inspection method Inspection WI Low-Medium Output Format When creating documents, structure output as:
