Use Poisson Capability Analysis to determine whether the rate of defects per unit (DPU) meets customer requirements. Use this analysis when you count the defects on each item, and each item can have more than one defect. Using this analysis, you can do the following:
For example, a textile manufacturer wants to analyze whether the defect rate for a fabric meets specifications. The manufacturer uses Poisson capability analysis to determine the number of defects per 100 yards of fabric and to assess whether the defect rate is stable.
To perform Poisson capability analysis, choose .
