Calculate DPMO





Formula

The formula to calculate the Defects Per Million Opportunities (DPMO) is:

\[ DPMO = 1000000 \times \frac{D}{U \times O} \]

Where:

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.

Example Calculation

Let's assume the following values:

Using the formula to calculate the DPMO:

\[ DPMO = 1000000 \times \frac{50}{1000 \times 10} = 5000 \]

The DPMO is 5000.
