Importance of the Six Sigma Primary Metric

Primary Metric: The Six Sigma Primary Metric is mandatory! How does one know whether a project delivers on its objectives? Every project must choose the right metrics to determine success. Primary metrics serve as the center point for the work, ensuring that the project’s direction and decisions are data-driven. This metric is what stakeholders will…

Six Sigma Metrics

Six Sigma practitioners use many Six Sigma metrics and/or measures of performance. In addition to the ones we will cover here, several others (Sigma level, Cp, Cpk, Pp, Ppk, takt time, cycle time, utilization, etc.) will be covered in other articles. The Six Sigma metrics of interest in the Define phase are: Defects per Unit…
