DPO and DPMO

DPO

DPO is defects per opportunity for the pinned snapshot.

highlighted = computed this step

Defects per Opportunity

DPO divides defects by total opportunities.

DPO=defectstotal opportunities\text{DPO}=\frac{\text{defects}}{\text{total opportunities}}

Compute DPO

The exact DPO is 1/50.

8400=1/50\frac{8}{400}=1/50
