From a Day to an Hour
At my last job, a truck suspension shop, we did inventory every December and it was someone’s job to count all the washers and screws of every size.
It was my first inventory and I casually mentioned that they should just weigh 10 screws or washers, then weigh them all and divide the weight to get the count. Everyone looked at me like I had given them the key to the universe.
Counting washers and screws went from a day or two, to just an hour. Credit: Reddit/codymreese
