Re: Random selection of 10%



fixed

Bill,

How can you determine at the beginning of the day how many you will process?

But do you not do a weight check? If a parcel is off a number of grams of the calculated weight you take that parcel out.

Or take a divider for each hour: first hour every nth parcel to check, next hour xth parcel. you can change the interval.

Now obviously we could count each Case and pull every 10th Case for audit.
But it would not take long for someone to figure this out - and if they
were so inclined - only short Cases other than the 10th in line.

Is there an algorithm/logic that we could employ to randomly pull Cases
that would equate to 10% over the course of a day but not be every 10th
Case? (My logic brain is on strike today and I can't think of a way to
design this.)
