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

Key Principles

Priority Hierarchy (from A3CriticalThinking):

1. SAFETY FIRST     → Never compromise for cost or delivery
2. CUSTOMER VALUE   → Quality that meets/exceeds requirements
3. SHAREHOLDER VALUE → Optimize after 1 & 2 are secured

1. Safety First: Always lead with safety considerations - this is non-negotiable
2. Clarity Over Brevity: Be clear, even if it takes more words
3. Visual Communication: A picture is worth 1000 words
4. Measurable Requirements: Specific, measurable acceptance criteria
5. Traceability: Link to higher-level documents and standards
6. Living Documents: Build in revision and improvement processes
7. Problem Solving: Use A3 methodology for issues and improvements
