While reasearching techniques related to SCM, I came across this really funny description of Physical Inventory.
So it's the end of the year and the warehouse workers and all the salaried employees are gathered together on a Saturday morning to perform the annual physical inventory. The coffee and donuts help to put color into the faces and cover up the odors enveloping those who had overindulged themselves the night before. People are wandering around not sure what they should be doing, when the boss walks in with stacks of reports, cards, and colored stickers and says "OK here's how this is going to work." By noon it's obvious that less than half the warehouse has been counted and the pizza lunch has left everyone with an enthusiasm deficit. At two o'clock, one by one, people start approaching the boss with the reasons as to why they have to leave. Suddenly the pressure increases on those remaining to get finished. Five o'clock and the last of the counters are abandoning ship, there's an enormous pile of paperwork marked "discrepancies" and several piles of product marked "unknown," "what's this?" and "needs to be identified." The boss surveys the scene and instructs the people in charge of investigating the overwhelming pile of discrepancies to "just make the adjustments, we need to get out of here."
