Monthly Cv is always smoother than weekly or daily. makes sense that there is more variation in demand day to day then month to month, right? The time bucket for Cv should be the same as or smaller than your planning cycle. If your business moves slowly then quarterly or monthly might be the right period. Consumer goods on the other hand most often need daily or weekly planning. Note that you can always take daily standard deviation and mean and apply the results to weekly or monthly, but you can’t take monthly standard deviation and say anything about weekly or daily.

When calculating the CV to determine if a part is a good candidate for a pull system I have a dilema:
If I calcualte the CV using monthly demand the CV is less than 1. However, if I calculate the CV using weekly or daily demand data, the CV is tends to increase and be hihger than 1.
My question is: What level of granularity should a use to calculate the CV? Should I use monthly, weekly of daily demand data?

Thanks,
