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
