We actually JUST made this switch in the last few weeks.
Our CEO had a really good idea, which was to count all like parts on the same day. That will be defined wildly differently for everyone, I know.
But for us, an example is rear axles. We have a few varieties, and they all look a lot alike. If we let the system do its thing, we’d count some rear axles in week 1, some in week 2, etc.
But manually, we decide to do them all on one day. Then you don’t get these bogus swings when someone counts one part as a different part number. If there is an error, it’s observable that very day that you lost 2 of these but gained 2 of those.
Some axles might even be rare enough to fall into a B or C category, and we might not rectify a mistake for months if we let the algorithms run the thing.
