📊 Attribute Capability Analysis
Binomial capability (yield) · Poisson capability (defect rate) · PPM and process Z
Process capability for attribute data (conforming/nonconforming, defect counts): Binomial is used for pass/fail decisions (count of nonconforming items); Poisson is used for defect counts (count of defects). Enter "defects sample-size" per subgroup; the tool automatically computes p̄ or DPU, PPM, and process Z, then compares them against the target.
