## DPMO Formula

The following equation is used to calculate the defects per million opportunities of a manufactured good.

DPMO = 1000000 x D / (U x O)

- Where DPMO is the defects per million opportunities
- D is the number of defects
- U is the number of units
- O is the number of opportunities per unit.

In the case of the equation above equation, this is considering that there may be more than 1 opportunity for defect per manufactured good.

## DPMO Definition

DPMO stands for defects per million opportunities. In manufacturing, it’s a measure of how many defects would occur in a lot of goods with 1 million opportunities. It’s important to understand that it’s 1 million opportunities and not 1 million units, although they could be equal. This is because units often have more than one point of failure or opportunity for failure.

## DPMO Example

How to calculate DPMO?

**First, determine the total number of defects.**Measure the total number of defects in a sample of product.

**Next, determine the total number of units.**Measure the total number of units in the sample.

**Next, determine the total number of opportunities.**Determine the total number of opportunities for defects per unit.

**Finally, calculate the DPMO.**Using the formula, calculate the total defects per million opportunities.

## FAQ
