Successfully launching a defect minimization program requires a meticulous approach. First, identify the root causes of defects using robust data gathering and process mapping. This involves actively seeking potential failure areas within

Z-scores represent a crucial tool in the Lean Six Sigma methodology. They quantify how much a data point deviates from the central tendency. By adjusting raw data into standardized values, Z-scores facilitate a clearer understanding of specific data points compared to the entire dataset.
