In process improvement efforts, defects per million opportunities or DPMO (or nonconformities per million opportunities (NPMO)) is a measure of process performance. It is defined as

{\displaystyle {\text{DPMO}}={\frac {1,000,000\times {\mbox{number of defects}}}{{\mbox{number of units}}\times {\mbox{number of defects opportunities per unit}}}}}
A defect can be defined as a nonconformance of a quality characteristic (e.g. strength, width, response time) to its specification. DPMO is stated in opportunities per million units for convenience: processes that are considered highly capable (e.g., processes of Six Sigma quality) are those that experience fewer than 3.4 defects per million opportunities (or services provided).
Note that DPMO differs from reporting defective parts per million (PPM) in that it comprehends the possibility that a unit under inspection may be found to have multiple defects of the same type or may have multiple types of defects. Identifying specific opportunities for defects (and therefore how to count and categorize defects) is an art, but generally organizations consider the following when defining the number of opportunities per unit:
Knowledge of the process under study
Industry standards
When studying multiple types of defects, knowledge of the relative importance of each defect type in determining customer satisfaction
The time, effort, and cost to count and categorize defects in process output

DPMO provides a quantifiable measure of the number of defects in a process per million opportunities, offering insights into the efficiency and effectiveness of the process.
Jul 28, 2024 · DPMO stands for defects per million opportunities. It's a measure of process performance used to assess the quality of a process - e.g., the quality of a service or production. The lower the value of DPMO, the better, as it is tied …
Mar 6, 2024 · Defects per million opportunities (DPMO) offers a standardized way of quantifying the presence of defects in a process. It measures how many defects could potentially happen for every million opportunities where an error or discrepancy might occur.
In process improvement efforts, defects per million opportunities or DPMO (or nonconformities per million opportunities (NPMO)) is a measure of process performance. It is defined as
Feb 5, 2025 · If your organization does not produce a large volume of output, you can also calculate defects per thousand opportunities, or defects per hundred opportunities by multiplying by the appropriate number. Your DPMO value can also be converted to a Sigma Level value.
Dec 28, 2020 · Four of the most common measurements are Defects Per Unit (DPU), Defects per Million Opportunities (DPMO), Parts per Million Defective (PPM), and the Rolled Throughput Yield (RTY). The following provides how each is used.
DPMO stands for Defects Per Million Opportunities, a key metric used in quality management and process improvement. It measures the number of defects in a process relative to the total number of opportunities for defects to occur, expressed per one million opportunities.
Defects per opportunity (DPO) is the number of defects identified in a sample divided by the total number of defect opportunities. Examples: In the previous example we identified 15 defect opportunities per unit.
Dec 30, 2024 · Defects Per Million Opportunities (DPMO) measures the number of defects in a process per one million opportunities for making an error. It’s used to evaluate process performance and identify areas requiring improvement. By analyzing DPMO, we gain insights into the efficiency level of our operations.
Converting defect rates to a per million value becomes necessary when the performance of your process approaches Six Sigma. When this happens, the number of defects shrinks to virtually nothing....in fact, if you recall from the ‘What is Six Sigma’ module, it's …
