Answer:
c-chart
Explanation:
A c-chart is a statistical process chart that is used to control the number of defects per unit of output. The attributes of the output units are collected in subgroups (of the same size). The c-charts show the number of defects (or nonconformities) per subgroup, and how their number changes over time.
In this case the nonconformities or defects would be the late deliveries.
