I want to understand if the coefficient of variation ($c_v$) is the right calculation to use for measuring how far off I am when shipping goods to customers. The date I want to ship to customers is the
target date and the date I do ship to customers is the
For my orders, if I took $c_v$ of
target date - ship date, would that be a normalized way to measure how far off I am to my target ship dates? Some additional details:
- Some goods take longer than others to produce and get ready to ship
- I want to penalize myself both for shipping early and late. Late is obviously bad. Early is bad too, as I am probably late on something else.
This results in negative numbers in the aggregation (i.e., if I generally ship late), which Wikipedia says was not good for coefficient of variation.
