Theory of Escaping Defects
No matter how good your inspection and test procedures are, the more defects you create, the more defects escape to the customer!
Defects and Hidden Factory
Each defect costs: time, money & man power!
- Caused by manufacturing variation
- Increase cost
- Lost capacity / yield decrease as the scrap is removed

Sigma Level is a statistical unit of measure that reflects Process Capability. The Sigma scale of measure is perfectly correlated to characteristics such as defects per unit, parts per million and the probability of defect or error.
