Which one of the following describes how to calculate DPMO?

DPMO, or Defects Per Million Opportunities, is a key metric used in quality management, particularly within Six Sigma methodologies. It quantifies the number of defects in a process by relating the number of defects to the total number of opportunities for error, scaled to a per-million basis.

The calculation involves taking the number of defects and dividing it by the total number of opportunities for those defects to occur. This ratio is then multiplied by one million to express the result per million opportunities. This standardized approach allows for a clear comparison of quality across different processes or products, regardless of the scale of production.

In this case, the correct method of calculating DPMO is to divide the number of defects by the number of opportunities, and then multiply that result by one million. This emphasizes the relationship between defects and the opportunities that exist for errors, providing a clearer picture of performance and quality within a process.
