Enter the number of defects found internally and the number of defects found externally into the Defect Removal Efficiency Calculator. The calculator will evaluate the Defect Removal Efficiency.
- Defect Rate Calculator
- DPMO Calculator (Defects Per Million Opportunities)
- Rejection Percentage Calculator
Defect Removal Efficiency Formula
The following two example problems outline the steps and information needed to calculate the Defect Removal Efficiency.
DRE = DI / (DI + DE) * 100
Variables:
- DRE is the Defect Removal Efficiency (%)
- DI is the number of defects found internally
- DE is the number of defects found externally
How to Calculate Defect Removal Efficiency?
The following steps outline how to calculate the Defect Removal Efficiency.
- First, determine the number of defects found internally.
- Next, determine the number of defects found externally.
- Next, gather the formula from above = DRE = DI / (DI + DE) * 100.
- Finally, calculate the Defect Removal Efficiency.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem :
Use the following variables as an example problem to test your knowledge.
number of defects found internally = 300
number of defects found externally = 80
DRE = DI / (DI + DE) * 100 = ?
