Two fundamental types of Six Sigma metrics include defects per unit (DPU) and process capability. Defects per unit (DPU) quantifies the average number of defects in a product or process, providing insights into quality levels. Process capability measures the ability of a process to consistently produce output within specified limits, indicating the process’s effectiveness and potential for improvement.
Defects Per Million Opportunities (DPMO)
Calculate the Defects Per Million Opportunities (DPMO) by dividing the total number of defects by the total number of opportunities and multiplying the result by one million. When assessing DPMO, it’s crucial to understand its significance in measuring process performance.
Here are some key points to grasp the concept effectively:
- Definition: DPMO quantifies the number of defects per one million opportunities in a process.
- Primary Metrics: DPMO is one of the primary metrics used in Six Sigma methodology to evaluate process quality.
- Calculation: DPMO = (Total Defects / Total Opportunities) * 1,000,000.
- Benchmarking: Lower DPMO values indicate better process performance, with Six Sigma aiming for 3.4 defects per million opportunities.
Process Capability Index (Cp & Cpk)
Analyzing process capability through the calculation of Cp and Cpk values provides insights into the performance and potential of a system.
The process capability index, Cp, measures how well the process variation fits within the specified limits, indicating the potential for defects. A Cp value greater than 1 signifies that the process spread is smaller than the tolerance range.
Cpk considers both the process centering and spread, providing a more comprehensive view of process performance. A Cpk value greater than 1 indicates that the process mean is well-centered within the tolerance limits.
Understanding Cp and Cpk values helps organizations assess and improve their processes to meet customer requirements effectively.
First Time Yield (FTY) and Rolled Throughput Yield (RTY)
Achieve a clear understanding of First Time Yield (FTY) and Rolled Throughput Yield (RTY) by evaluating their impact on process efficiency and overall quality.
FTY measures the percentage of units that pass through a process step without any rework or defects. It helps identify areas for improvement within a single process step.
RTY calculates the overall probability of producing a defect-free unit through multiple process steps.
By analyzing standard deviation and using control charts, you can monitor the variation in FTY and RTY over time.
Improving FTY at each step enhances the overall throughput yield, ensuring higher quality outputs and increased efficiency in your processes.
Sigma Level
To determine the Sigma Level of a process, you need to assess the capability of meeting customer specifications while considering variations in quality. Sigma Level in Six Sigma metrics refers to the standard deviation of a process, indicating how well it performs within customer requirements.
The Sigma Level is calculated using formulas that consider defects per million opportunities (DPMO) or the process capability index (Cp). A higher Sigma Level signifies better process performance and fewer defects, aligning with the Six Sigma methodology’s pursuit of near-perfect quality.
Understanding Sigma Level through proper metrics and formulas allows organizations to quantify their process quality, identify areas for improvement, and strive for continuous enhancement in meeting customer expectations.

The formula for DPMO involves multiplying the number of defects by one million and then dividing by the total number of opportunities for defects. This formula is represented as DPMO = (Number of Defects / Total Opportunities) * 1,000,000.
Formula for Cp & Cpk
To calculate Cp & Cpk in Lean Six Sigma, you assess process capability using specific formulas.
Cp measures the process capability for a stable process with a normal distribution, comparing the spread of the process to the specification limits. The formula for Cp is (USL – LSL) / (6 * standard deviation). A Cp value greater than 1 indicates that the process spread is less than the specification limits, showing a capable process.
Cpk considers how well the processing center aligns with the specification limits. The formula for Cpk is the minimum of (USL – μ) / (3 * standard deviation) or (μ – LSL) / (3 * standard deviation), where μ is the process mean. A Cpk value greater than 1 signifies a capable process with the center aligned within the specification limits.
Formula for FTY & RTY
Calculate FTY and RTY metrics to evaluate process performance in Lean Six Sigma.
FTY, or First Time Yield, measures the percentage of processes that produce a good unit without any defects. The formula for FTY is the number of good units produced divided by the total number of units started in a process.
RTY, or Rolled Throughput Yield, evaluates the overall quality control of a process by considering the cumulative effect of multiple processes producing defective units. The RTY formula is calculated by multiplying the FTY of each individual process together.
These metrics are crucial in understanding the efficiency and effectiveness of processes within your Lean Six Sigma initiatives.
Formula for Sigma Level
The Sigma Level formula quantifies the capability of a process to perform within specified limits, building upon the foundational metrics of FTY and RTY in Lean Six Sigma.
To calculate the Sigma Level of the process output, you need to first determine the number of defects per million opportunities (DPMO). This involves counting the defects in a sample and extrapolating to a million units.
