$97\%$ throughput yield is not bad, but how good is it in the grand scheme of things? Let$$s do some quality performance calculations to figure out where your organization$$s performance stands. Some of your units have more than one defect. As a result, there are $78$ defects total in one day. There are $3$ opportunities for a defect to occur in one unit, meaning the hole could be messed up$,$ the length could be wrong, and$/$or the width could be wrong. Calculate the following quality metrics below.

ROUND $5$ QUALITY PERFORMANCE

Number of defects DF $($given$)$: DF $=\_\_\_\_\_$

Number of opportunities per unit OP $($given$)$: OP $=\_\_\_\_\_$

Total output TO$4$: TO$4=\_\_\_\_\_$

Number of units with defects:

# Units with Defects$=$TO$\_4-$DAO$\_5$

# Units with Defects $=\_\_\_\_\_$

Average number of defects per unit $($uses total output rather than # units with defects$)$:
