It's the Paper, Stupid --Dickeson

The faster we turn over paper, the more profit we make. Follow that paper!

But how shall we follow the paper? Track the time it sleeps in raw inventory. Time becomes the process measurement key. The moment paper is placed in raw inventory the clock begins to tick. How long does it stay in raw inventory? (When it's snoozing in raw inventory we're not making a nickel.) We have to know the date and time each roll or package of paper was received. We need to know the date and time it left raw inventory for a job. Subtract issue time from time of receiving in inventory and you have the paper dwell-time as raw material. The greater that dwell-time, the less the profit. It's that simple.
