Six Sigma Defect Metrics
Six Sigma Defect Metrics
In this tutorial, we will learn about Six Sigma Defect metrics. Some of the defect metrics are as follows:
- Proportion Defective
- Yield
- DPU(Defects Per Unit)
- DPO(Defects Per Opportunity)
- DPMO(Defects Per Million Opportunities)
Proportion Defective (p)
Proportion Defective(p) = Number Of Defective Units / Total Number of Production Units
Yield
Yield = (Total Number of Product Units – Number Of Defective Units )/ Total Number of Production Units
or
Yield(Y) = 1 – p
Defects Per Unit( DPU)
Defects per unit(DPU)= Total Number Of Defective Units/ Total Number Of Production Units
Defects Per Opportunity(DPO)
Defects Per Opportunity(DPO) = Total Number Of Defective Units / (Total Number Of Production Units * Number Of Defect Opportunities Per Unit)
Defects Per Million Opportunities (DPMO)
Defects Per Million Opportunities(DPMO) = DPO * 1,000,000
That’s it. We have successfully learned about Six Sigma Defect metrics.
