1.1 ACCEPTANCE OF LOTS
• What ? screening of arriving product lots to ensure adequate quality for use
• Why? Because putting parts into production when they are out of spec. will probably result in out of spec. product. This will cost much more.
• Advantages,
- focuses quality problems on source
- reduces inspection required
- can use destructive testing
- rejection of entire lots increases supplier quality incentives
- uses known risks and probabilities
• Disadvantages,
- good/bad lots may be rejected/accepted without reason
- planning and documentation required
- only describes part of a lot
