Understanding ASQ Calculations
Key Concepts
- Acceptance sampling determines lot quality based on sample inspection
- Operating Characteristic (OC) curve shows acceptance probability
- AQL defines acceptable quality level for producer's risk
- Sample size affects discrimination power of sampling plan
Quality Metrics
- Producer's Risk (α): Probability of rejecting good lots
- Consumer's Risk (β): Probability of accepting bad lots
- Average Outgoing Quality (AOQ): Expected quality after inspection
- Effectiveness Index: Overall sampling plan performance
Recommendations
Sample Size
Sample size is adequate for lot size
Acceptance Number
Acceptance criteria is appropriate
Risk Management
High producer risk - consider adjusting sampling plan
Inspection Level
Inspection level provides good coverage
